The softest men's underwear is usually made from modal, fine cotton or a silky stretch blend, paired with flat seams, a tag-free label and a waistband that does not dig in. Fabric matters, but so do the details you feel against your skin all day. Here is how the main soft options compare and how to choose between them.
What "soft" really depends on
Softness is not just the fibre. Four things decide how a pair feels after hours of wear, and it helps to check all of them before you buy:
- The fabric: modal and silk-like knits feel smooth, cotton feels familiar and matte.
- The seams: flat stitching sits against the skin instead of ridging.
- The label: a printed or tag-free label removes a common annoyance.
- The waistband: elastic that stays put without pinching.
A pair that gets all four right feels like nothing at all, which is exactly the goal of everyday underwear.
Cotton: the familiar choice
Cotton is the fabric most men grew up wearing. It has a dry, natural hand-feel and is easy to wash. Our Cotton Underwear Moisture Wicking Briefs use 95% cotton and 5% spandex, so they stay close to the body without losing the natural feel. They are tagless and come in eight colours.
The Cotton Tag-Free Briefs add a 3D pouch and an elastic waistband that keeps its shape through a long day. Our cotton collection has more cuts to compare, and you can see how cotton stacks up against other knits in our mesh vs cotton vs modal comparison.
Modal and ice silk: the smooth option
Modal is a soft, drapey fibre that feels cooler and smoother than most cotton. Silk-like blends, often sold as "ice silk", take that further with a slick surface that slides easily under clothes.
The Ice Silk Trunks are made from soft modal that dries fast and keeps its shape, with flat seams, a low-rise cut and mesh panels for airflow. The Silk Breathable Boxer Briefs use a dual-colour silky fabric with a stretchy waistband and a contour pouch. Both run small, so size up. For more detail, read our ice silk underwear guide.
Quick comparison
| Fabric | Feel | Best for |
|---|---|---|
| Cotton | Natural, matte, familiar | Everyday wear, easy care |
| Modal | Smooth, cool, lightweight | Warm days, long wear |
| Silk-like blends | Slick, silky, light | Under fitted trousers, a sleek feel |
| Mesh | Open, airy | Heat, workouts, styling |
How to choose your pair
- Start with the seams and label. If something bothers you, look for flat seams and a tag-free design first.
- Match fabric to the day. Cotton for relaxed days, modal or silk-like for heat or tight clothes.
- Check the size chart. A band that is too tight feels rough in any fabric. Several of our styles run small, so size up.
- Rotate pairs. A mix of cotton and modal covers most situations.
Keeping soft fabrics soft
Wash on a gentle cycle at a low temperature, skip fabric softener and air dry when you can. Washing inside out and keeping pairs away from rough items such as zips and towels also helps the surface stay smooth. Our guide on how to wash men's underwear covers the full routine.

Frequently asked questions
What is the softest fabric for men's underwear?
Modal and silk-like blends feel the smoothest to most people, while good cotton feels softer after a few washes. It comes down to preference.
Is cotton or modal better for everyday wear?
Both work. Cotton is natural and easy to care for, modal is lighter and smoother. Many men keep both in rotation.
Do tag-free labels matter?
Many men find a tag-free design more comfortable because there is nothing at the back of the waistband to notice.
Should I size up in silky underwear?
Our silky boxer briefs and ice silk trunks run small, so sizing up is recommended. Check the size chart on each product page.
