Our men's trunk underwear style is low rise and ultra comfortable. The pouch is engineered with elastic edging to cup and support closely to the body. The long leg has a soft bind to avoid riding up during the day and fits wide thighs without digging in.

Created with soft sustainable fabric Tencel ® and in-house developed recycled elastic, logo printed with Oeko-Tex certified silicon. Sizing info

TENCEL™ is an eco-friendly fiber made from responsibly sourced wood pulp. The wood pulp is dissolved in a closed-loop process with a non-toxic organic solvent, then the solution is forced through tiny holes in order to create an absorbent biodegradable fiber that feels softer and lighter than cotton.

A good everyday trunk

Ordered the boyf a pair when I was ordering my own third etc pair. The sizing was true to the chart - he's usually a 38 and the XL were comfy. Fabric is soft and breathable. The legs weren't as long on this 6'1 person as on the model, but were long enough for a bigger thigh. He ranks them as a nice midway point between Step Ones and Target basics for hold. A good everyday trunk.

Great for preventing chafe

I got these to wear under dresses like bike shorts to prevent chub rub, and I'd say they are definitely great at preventing chafe. They are super comfy and stretchy, and I haven't had them ride or roll up. They don't dig into your legs at all, and I wore them under thin polyester work pants that normally chafe me and you could barely see them.
The only negative I can see is they aren't 100% solidly opaque, which only barely matters if you get your skirt blown up in the wind. You definitely wouldn't be flashing anyone though.
My thighs say thank you!

Comfy trunks

Super soft to touch, stretchy, and smart looking men's trunks. That they are sustainably made is the cherry on top of a great product.
