If you have spent any time researching merino wool for travel, two brands come up constantly: Unbound Merino and Woolly Clothing Co. Both have built loyal followings among travelers who want odor-resistant, packable basics that can handle days of wear between washes. Both sell direct-to-consumer. And both promise to simplify your travel wardrobe.
But they are not the same product at the same price point, and choosing between them is not as simple as picking whichever shows up first in a search result. Unbound positions itself as a premium merino brand with meticulous fabric sourcing. Woolly targets travelers who want genuine merino performance without the sticker shock.
We have worn both extensively — across long-haul flights, humid Southeast Asian cities, European walking days, and plenty of hotel-sink hand-washing sessions. Here is how they actually compare when the packing cubes are zipped and the itinerary gets real.

The Brands at a Glance
Unbound Merino
Founded in 2016 after a successful Kickstarter campaign, Unbound Merino has become one of the most recognized names in travel merino. Their pitch is straightforward: pack less, travel more. The brand sources high-quality merino from Australia and New Zealand and focuses on a curated lineup of travel essentials rather than trying to build a full fashion label. Everything in their catalog is designed around the idea that you should be able to wear it for days without washing.
Woolly Clothing Co.
Woolly has been around since 2014, making them one of the earlier direct-to-consumer merino brands aimed at everyday and travel use. They offer a wider range of styles and weights at noticeably lower prices than most premium merino competitors. Their approach is less about minimalist branding and more about making merino wool accessible to people who want the performance benefits but cannot justify spending $80 or more on a single t-shirt.
Fabric Weight and Construction
This is where the first meaningful differences appear.
Unbound Merino uses a 195 GSM (grams per square meter) fabric for their core crew neck tee. It is a midweight merino that strikes a balance between durability and breathability. The fabric has a smooth, almost silky hand feel that does not read as “athletic wear.” It looks and drapes like a quality conventional t-shirt, which matters if you are wearing it to dinner, not just on a hiking trail.
Woolly offers multiple weight options, which is actually one of their advantages. Their Ultralight line comes in around 150 GSM, their standard tees land near 170-180 GSM, and they have heavier options as well. The lighter weight makes Woolly tees slightly more breathable in hot climates but also slightly less substantial in feel. You can feel the difference when you hold both shirts — the Unbound tee has more heft and a denser knit.
Neither brand publishes exact micron counts prominently, but both use fine merino in the 17.5 to 19.5 micron range. At these fiber diameters, neither shirt should feel itchy against bare skin, even for people who find coarser wool uncomfortable. If you are new to merino and worried about scratchiness, both brands have largely solved that problem.
Pro Tip: If you run hot or travel primarily in tropical climates, Woolly’s lighter-weight options give you a genuine advantage. If you want one shirt that works from air-conditioned offices to cool evening walks, Unbound’s midweight fabric is more versatile across temperature ranges.

Odor Resistance
This is the headline feature for any merino travel shirt, and both brands deliver on the promise — but not identically.
Unbound Merino consistently performs at the top of the merino category for odor resistance. Their 195 GSM fabric, combined with what appears to be a tighter knit structure, handles multi-day wear remarkably well. Three days of moderate activity in temperate weather without any noticeable odor is realistic, and some travelers report stretching to four or five days in cooler conditions. The shirt does not develop that stale, lived-in smell that synthetic fabrics pick up within hours.
Woolly performs well on odor resistance — better than any synthetic and on par with most merino competitors — but the lighter-weight options do not quite match Unbound’s staying power. The thinner fabric seems to reach its limit a bit sooner, particularly in hot, humid conditions. Two to three days of moderate wear is a reliable expectation. Their heavier-weight options close the gap considerably.
The difference is subtle enough that most travelers would be satisfied with either brand. But if you are specifically buying merino to maximize days between washes on a long trip, Unbound has a slight edge here.

Durability and Pilling
Merino wool has a reputation for being delicate, and it is a fair concern. Both brands use fine-micron fibers that are inherently more prone to pilling than coarser wool or synthetic fabrics. But they handle this challenge differently.
Unbound Merino’s denser, heavier fabric resists pilling better over time. After months of regular wear and washing, you will see some pilling — that is unavoidable with any merino at this fiber diameter — but it remains minimal and manageable with an occasional pass of a fabric shaver. The fabric also holds its shape well, resisting the stretched-out neckline problem that plagues cheaper knits.
Woolly’s lighter-weight tees are slightly more prone to pilling, especially in high-friction areas like under backpack straps or where a seatbelt crosses your chest. The trade-off for a thinner, more breathable fabric is that it shows wear a bit sooner. That said, Woolly’s construction quality is solid for the price point, and their shirts hold up to regular hand-washing without falling apart.
Both brands recommend cold washing and air drying, which significantly extends the life of any merino garment. If you follow the care instructions, either shirt should last through years of travel. Throw them in a hot dryer regularly, and neither brand can save you.
Pro Tip: A small fabric shaver (they weigh almost nothing) is worth tossing in your toiletry bag if you travel with merino. Five minutes of de-pilling every few weeks keeps either brand looking fresh. For complete care instructions, check our guide on merino wool care guide.
Fit and Sizing
Fit is subjective and body-dependent, but there are consistent patterns worth noting.
Unbound Merino Fit
Unbound cuts their shirts in what they call a “modern” fit — not slim, not boxy. It sits closer to the body than a traditional t-shirt but is not skin-tight. The sleeve length hits at a flattering mid-bicep point, and the body length is designed to stay tucked or look clean untucked. The neckline is well-reinforced and does not stretch out after repeated wear.
Sizing runs true for most body types, though broader-shouldered individuals sometimes size up. Their size chart is accurate and worth consulting before ordering.
Woolly Fit
Woolly’s fit varies somewhat across their product lines, which is worth noting if you order multiple styles. Their standard crew neck runs slightly more relaxed than Unbound — closer to a traditional American t-shirt fit. Some travelers prefer this, especially in warm climates where a bit more airflow is welcome. Others find it slightly less polished for situations where you want to look put-together.
Woolly offers a wider size range overall, which is an advantage if you fall outside the medium-to-large sweet spot that most travel clothing brands optimize for.
The Verdict on Fit
If you prefer a slightly more tailored, modern silhouette, Unbound is the better bet. If you like a relaxed, easy-wearing fit or need extended sizing, Woolly accommodates more body types and preferences.
Price and Value
Here is where the conversation gets practical.
Unbound Merino’s core crew neck tee typically retails around $85-$90 USD. They offer bundle pricing (three-packs, five-packs) that brings the per-shirt cost down, and they run occasional sales. But there is no getting around it — these are expensive t-shirts by any standard.
Woolly’s comparable merino tees typically retail in the $55-$65 range, with sales and bundles available as well. That is a meaningful $25-$30 difference per shirt, which adds up quickly if you are building a capsule wardrobe of three or four tees.
Is the Extra $25-$30 Worth It?
This depends entirely on how you travel and what you prioritize.
Unbound is worth the premium if:
- You take extended trips and want maximum days between washes
- You prefer a more refined fit and fabric hand feel
- You want slightly better long-term durability and pilling resistance
- You are building a small, high-quality capsule wardrobe and each piece needs to be exceptional
Woolly is the smarter buy if:
- You want genuine merino performance at a more accessible price
- You are building your first merino travel wardrobe and want to try multiple pieces without a massive upfront investment
- You travel primarily in hot climates where lighter-weight fabric is preferable
- You tend to be hard on clothes and would rather replace a $60 shirt than nurse a $90 one
Neither choice is wrong. Both give you the core merino benefits — odor resistance, temperature regulation, quick drying, packability — that make wool so compelling for travel. The question is whether the incremental improvements in Unbound’s fabric justify a 40-50% price premium for your specific use case.

Beyond T-Shirts: Comparing the Full Product Lines
Both brands have expanded well beyond basic tees, and the comparison extends across their lineups.
Long-Sleeve Shirts
Both offer merino long-sleeve options. Unbound’s long-sleeve crew uses the same 195 GSM fabric as their tee and works exceptionally well as a layering piece or standalone shirt in cooler weather. Woolly’s long-sleeve options are lighter and slightly more affordable, following the same pattern as their tees.
Underwear
This is a category where merino really shines for travelers, and both brands offer boxer briefs. Unbound’s merino underwear uses a slightly different fabric blend and has a loyal following among long-term travelers who swear by multi-day merino underwear performance. Woolly’s merino underwear is priced lower and performs well, though the lighter fabric does not quite match the odor resistance of heavier-weight options.
Hoodies and Outerwear
Unbound’s merino hoodie is one of their standout products — a midweight zip-up that works as a travel layer, casual jacket, or airplane comfort piece. It is expensive but genuinely versatile. Woolly offers hoodies and pullovers at lower price points with good performance, though the fabrics tend to feel thinner.
Socks and Accessories
Woolly has a broader accessory range, including beanies, buffs, and various sock weights. Unbound’s accessory lineup is more curated but well-executed.
Pro Tip: If you are building a complete merino travel wardrobe, mixing brands is a perfectly valid strategy. Unbound tees for daily wear where odor resistance matters most, Woolly underwear and socks where the price difference adds up and the performance gap is smaller.

FAQ
Is Unbound Merino really worth the higher price?
For travelers who prioritize maximum odor resistance and a refined fit, yes — the fabric quality justifies the premium. But Woolly delivers roughly 80-85% of the performance at 60-70% of the cost, which is a compelling value proposition for many travelers. The answer depends on your budget and how much you value those incremental improvements.
Do both brands use 100% merino wool?
Both brands use 100% merino wool in their core t-shirt offerings. Some items in their extended product lines (underwear, certain blends) may incorporate small percentages of nylon or elastane for stretch and durability, which is standard practice and generally improves garment longevity without sacrificing the key merino benefits.
How do Unbound Merino and Woolly compare on shrinkage?
Both brands pre-treat their fabrics to minimize shrinkage, but merino wool can still shrink if machine-washed in hot water or tumble-dried on high heat. Following the care instructions — cold wash, air dry — prevents this with both brands. If you do accidentally shrink a shirt, Unbound’s denser fabric seems to tolerate the abuse slightly better, though neither brand is immune.
Can I wear either brand’s tee for business casual settings?
Unbound’s crew neck has a cleaner drape and a fabric quality that reads more “nice t-shirt” than “athletic base layer,” making it slightly better suited for smart-casual settings. Woolly’s relaxed fit reads more casual. That said, neither brand’s crew neck tee is truly business casual on its own — pair either with a blazer or sport coat and you are fine.
Which brand is better for hot and humid climates?
Woolly’s lighter-weight options (150 GSM range) have an edge in extreme heat and humidity. The thinner fabric allows more airflow and dries faster after sweating. Unbound’s midweight fabric is still excellent in warm conditions — merino regulates temperature well regardless — but the lighter Woolly tees feel noticeably more breathable when the mercury climbs past 30 degrees Celsius.
How long do these shirts realistically last with regular travel use?
With proper care (cold wash, air dry, occasional de-pilling), expect 2-3 years of regular travel use from either brand. Unbound’s heavier fabric tends to show wear slightly more slowly, but the difference is measured in months, not years. Both brands will outlast cheap synthetic travel shirts that pill and stink within a season.
The Bottom Line
Unbound Merino and Woolly Clothing Co. are both legitimate options for travelers building a merino wardrobe. Unbound earns its premium pricing with superior fabric weight, slightly better odor resistance, and a more refined fit. Woolly counters with genuine merino performance at a significantly lower price point and more variety in weights and styles.
The best choice is the one that matches your travel style, budget, and priorities. And honestly, you will not be disappointed with either — both are miles ahead of the cotton and polyester alternatives sitting in most travelers’ drawers right now.
