Which Material Is Best for Men’s Underwear?
The Verdict: The "best" material depends on your activity. Cotton is decent for casual wear but handles sweat poorly. Polyester is durable but is essentially plastic that traps odors. Micro Modal Air is widely considered the best overall fabric for daily wear because it offers the softness of silk with superior breathability and moisture-wicking properties.
Comfort starts with fabric. At SilkCut, we believe that if you are uncomfortable, nothing else matters. But with so many options on the shelf—Bamboo, Spandex, Cotton, Modal—how do you choose? We broke down the pros and cons of each.
The Fabric Showdown: Pros & Cons
1. Cotton (The Old Standard)
What is it? A natural fiber grown from cotton plants. It’s the most common and affordable option.
- Pros: Affordable, widely available, decent breathability.
- Cons: Absorbs and holds sweat (leading to "swamp crotch"), loses shape quickly, gets rough after washing.
2. Polyester (The Synthetic Trap)
What is it? A synthetic, plastic-based fiber derived from petroleum.
- Pros: Cheap and durable.
- Cons: It is essentially plastic. It traps heat and bacteria, leading to persistent odors ("permastink") that are hard to wash out. It also lacks the natural softness of botanical fibers.
3. Micro Modal Air® (The Premium Choice)
What is it? A semi-synthetic fiber made from the pulp of sustainable beechwood trees.
- Pros: 3x softer than cotton, 50% more absorbent (keeps you dry), naturally breathable, resists shrinking.
- Cons: Costs more to produce than cotton.

Quick Guide: Which Fabric is Best for You?
If you are looking for a specific benefit, here is how the materials rank:
🏆 Best for Daily Comfort
Micro Modal Air. Its "second-skin" feel and temperature regulation make it unbeatable for 12+ hours of wear.
🏃 Best for High-Sweat Workouts
Ventilated Micro Modal (Mesh). Avoid polyester, which traps sweat. Instead, use High Performance Mesh to get airflow without the plastic feel.
🛡️ Best for Sensitive Skin
Micro Modal Air. Unlike cotton (which gets rough) or wool (which itches), Modal's smooth surface prevents dermatitis.
What About Silk?
Some men prefer the idea of luxury materials like silk. While silk is excellent for thermal regulation, it is fragile and difficult to wash. That is why we upgraded to Modal—it offers the feeling of silk without the high-maintenance care. (Read our full comparison: Silk vs. Modern Fabrics).
