FAQs

Can I try the Boxer Brief risk-free?
+

Yes. Our First Pair Guarantee covers one pair of each unique style and size in your order, so you can try it on and return it risk-free if it's not right. Just keep any duplicate pairs unopened and unworn in case you need to swap. Found your fit? Men's Underwear is 3 pairs for $80, so it's an easy way to stock up.

What is the Men's Boxer Brief made of?
+

The body is 95% certified organic cotton and 5% elastane for stretch. The waistband elastic is 70% recycled polyester and 30% spandex, and the label is 100% polyester satin jacquard. It's all GOTS-certified, so it's grown and processed without pesticides or PFAS.

What makes the Boxer Brief comfortable for all-day wear?
+

A functional front fly and an ergonomic pouch give it shape and room where you need it. Flatlock seaming means no rough seam lines or chafing under clothes, and the waistband is soft enough that it won't dig in, even after a full day.

What size Men's Boxer Brief should I order?
+

Our Men's Underwear runs S to 2XL. S fits a 30-31" waist and 36-37" hip, M fits a 32-33" waist and 38-39" hip, L fits a 34-35" waist and 40-41" hip, XL fits a 36-37.5" waist and 42-44.5" hip, and 2XL fits a 38-40" waist and 45-47.5" hip.

What's the rise and inseam on the Men's Boxer Brief?
+

The Boxer Brief sits at a mid rise, right at the middle of your waist, with a medium 4" inseam and a classic slim fit through the leg. It's designed to be a reliable first layer –not too long and not too short.

    Perfect for me

    Excellent fit and comfort. I vary between a 32-34 inch waist and have probably larger than average thighs. Assuming these have reasonable durability, I'll definitely be buying these again.

    Soft and Confortable

    I didn't expect this product to be so soft and comfortable. Good stretch and nice leg width, the cotton is very comfortable and feels fresh throughout the day.

    The whole package!

    That may or may not be a pun. Anyway, I’d been searching for the right balance between sustainability, comfort, and durability for years, but the search stopped with Subset! And they also introduced me to the trashie bag, so when the garments do eventually wear out, I can send them back with the comforting thought that they’ll be put back into the recycle stream instead of a landfill. My only critique is that they don’t offer more clothing options!

    Great product

    Birthdays organic cotton boxer brace for my husband, I have been slowly replacing his toxic boxers with non-toxic ones. He likes them they are very comfortable. We'll probably get more for him in the future.
