The fabric decides how underwear feels after eight hours, not just in the first minute. Mesh, cotton and modal (often sold as "ice silk") are the three most common choices for men's underwear, and each one suits a different day. Here's how they compare.
Quick comparison
| Fabric | Best for | Breathability | Dries fast | Feel |
|---|---|---|---|---|
| Mesh | Gym, hot weather, going out | Highest | Yes | Light, airy |
| Cotton | Everyday, sleeping | Good | No | Soft, familiar |
| Modal / ice silk | All-day wear, work, travel | Very good | Yes | Smooth, cool, silky |
Mesh underwear
Mesh is knitted with tiny open holes, so air moves straight through. That makes it the coolest option on a hot day or during a workout. Modern mesh is soft and stretchy rather than scratchy, and the see-through look is part of the appeal for many men.
- Pros: maximum airflow, dries quickly, light as nothing.
- Cons: less coverage, and less warm in winter.
Try: Mesh Boxer Briefs, available in 12 colours.
Cotton underwear
Cotton is the classic. It's soft, gentle on skin and easy to care for. The downside is that cotton absorbs sweat and holds on to it, so it can feel damp during exercise or on a hot day.
- Pros: soft, durable, comfortable for everyday and for sleeping.
- Cons: slow to dry, can lose shape over time without a bit of elastane.
Modal and "ice silk" underwear
Modal is a soft fibre made from beech wood pulp. Blended with elastane, it becomes what many brands call ice silk: smooth, cool to the touch, stretchy and quick-drying. It keeps its shape well and feels almost weightless, which is why it's popular for long days at work or travelling.
- Pros: silky feel, wicks moisture, holds its shape, no ride-up.
- Cons: needs a gentle wash to stay soft.
Try: Ice Silk Trunks, with a 3D contour pouch.
Which fabric should you choose?
- You train a lot or run hot: mesh.
- You want all-day comfort at work: modal / ice silk.
- You want something simple for home and sleep: cotton.
Most men end up with a mix: a few mesh pairs for the gym, modal for workdays and cotton for weekends.
Frequently asked questions
Is mesh underwear good for the gym?
Yes. Mesh is the most breathable fabric, so it keeps you cooler and drier during exercise than cotton.
What is ice silk underwear made of?
Usually a blend of modal (or nylon) with elastane. The name describes the cool, smooth feel rather than real silk.
Which underwear fabric is best for sweating?
Mesh and modal both move moisture away from the skin and dry quickly. Cotton absorbs sweat and stays damp longer.
How should I wash mesh and modal underwear?
Wash at 30°C with similar colours, avoid fabric softener and bleach, and air-dry. Heat from a dryer wears out elastic faster.
