Cotton has been the default fabric for men's underwear for generations. TENCEL™ Lyocell is newer, less familiar, and often dismissed as a premium marketing term. This guide breaks down both fabrics honestly so you can decide what's actually right for you.
What Is TENCEL™ Lyocell?
TENCEL™ is a branded fibre made by Lenzing AG from wood pulp. The wood comes from certified or controlled sources, and the closed loop process recovers more than 99.8% of its solvent. The result is a semi-synthetic fibre with a genuinely distinct feel and performance profile.
It's the primary fabric in both the Roam Boxer Brief and Boxer Brief I. Read more about Nether's TENCEL™ Lyocell underwear.
Side-by-Side Comparison
| Property | Cotton | TENCEL™ Lyocell |
|---|---|---|
| Softness | Familiar, medium | Exceptionally smooth; silky hand feel |
| Moisture absorption | High — holds moisture | High — but releases it faster |
| Breathability | Good | Excellent |
| Drying speed | Slow | Faster than cotton |
| Sustainability | Conventional cotton is water-intensive | Closed-loop production; certified or controlled wood sources |
| Durability (wash) | Good | Equal or better when washed correctly |
| Pilling | Can pill with abrasion | Low pilling tendency |
| Skin sensitivity | Neutral | Naturally smoother; fewer irritation points |
When Cotton Has the Edge
Cotton is widely available, inexpensive, and deeply familiar. If you run cold, prefer heavier-weight fabrics, or simply find cotton comfortable, there's no reason to switch for the sake of switching.
When TENCEL™ Is Worth It
TENCEL™ outperforms cotton in most active or extended-wear scenarios:
- Hot weather or warm offices — Lyocell and Modal fibers support a natural dry feeling through moisture control
- Long travel days — faster moisture release means less clamminess over hours
- Sensitive skin — the smoother fibre surface reduces friction and irritation
- Sustainability-conscious buyers — the production process is meaningfully cleaner than conventional cotton
The Verdict
For everyday underwear, TENCEL™ Lyocell is a genuine upgrade over standard cotton — not a marginal one. The fabric feels noticeably better, performs better in heat and movement, and holds up through repeated washing.
