A natural, fresh, and seriously comfortable alternative
Tencel trunks have that little something extra. The moment you put them on, you feel an incredible lightness on the skin—a fresh, almost silky touch that easily outperforms cotton. Not rough, not sticky, not stifling. Just right. And behind that comfort? A technical and eco-friendly fabric: TENCEL™, also known as lyocell.
Made from wood pulp, Tencel is breathable, antibacterial, wrinkle-resistant, and incredibly soft. Paired with recycled ECONYL® polyamide and a touch of elastane, it creates a trunk that ticks every box for the perfect underwear:
- Remarkably lightweight, offering an unmatched second-skin feel
- Quick-drying, even after a workout or a scorching day
- Odor-resistant—let’s be honest, that’s no small detail
- Keeps its shape, without stretching out or creasing
- Breathable—for both you and your skin
A fabric made to move (and sweat in comfort)
Active? Sweaty? Good news—Tencel loves that. Thanks to its fiber structure, it absorbs moisture and wicks it away quickly, while preventing odor-causing bacteria from settling in. No lingering dampness. No discomfort. No discomfort at all, in fact.
Whether you’re going for a run, working all day in jeans, or lounging in shorts at 35°C, our Tencel trunks stay fresh and dry—no need for a wash between every wear.
Bluebuck Tencel trunks: our transparent composition
We’re not here to sell you dreams in bulk—here’s exactly what’s in our trunks:
- 55% TENCEL™ (lyocell): for freshness, softness, and breathability
- 40% recycled ECONYL® polyamide: for durability and lightness
- 5% elastane: for stretch, so they move with you
No surprises, no mystery fibers, no compromises. Each fabric serves a specific purpose. We chose them as much for their performance as for their minimal impact on the planet.
Eco-responsible down to the last stitch
Buying Tencel trunks is good. Choosing them from us is even better. At Bluebuck, we follow a simple policy:
- Ecological, organic, or recycled fabrics, carefully selected
- 100% European production, mainly in Portugal but also in Austria
- Factories powered by green electricity
- No sales, no seasonal collections—our designs are made to last
And on top of that, we donate 1% of our annual turnover to environmental organizations, like WWF. Yes, even on underwear. Especially on underwear.
Tencel trunks: perfect for hot days (and long nights)
Tencel isn’t just a “breathable” fabric—it’s a daily ally:
- Won’t itch, even after 12 hours sitting down
- Won’t cling, even at 30°C in the shade
- Won’t trap moisture, even during workouts
- Keeps its fit, wash after wash (and we know some of you put it to the test)
In short, a true comfort champion that stays in place and lets you move however and whenever you want.
Organic cotton is great—we use plenty of it at Bluebuck. But Tencel is a different experience. To put it simply:
- Cotton absorbs moisture, but takes longer to dry
- Tencel absorbs and dries quickly—no damp feeling
- Cotton can hold onto odors if you sweat a lot
- Tencel is naturally antibacterial—odors stay (almost) out
- Cotton wrinkles—Tencel always looks neat
Tencel trunks are perfect for anyone looking for a technical, breathable fabric that keeps up with your pace without missing a beat.
Yes, absolutely. Tencel trunks are built to move. Thanks to their ultra-lightweight, stretchy composition, they don’t pinch or chafe. And with their moisture management abilities, they prevent that “sauna” effect as soon as you start moving.
For sports, we recommend them for:
- Their breathable fabric that wicks away sweat
- Their comfortable support without stiffness
- Their durability, even after repeated washes and countless workouts
And on top of that, they dry quickly—you can rinse them in the evening and find them dry the next day. Perfect if you’re travelling light or if your locker space is a bit too cramped.
