Bamboo Cool Men's Long Boxer Briefs Review: Are They Really More Breathable?

Cotton underwear riding up mid-workout is one of my biggest pet peeves, so I gave Bamboo Cool's Long Underwear Men's Sports Underwear 3 Pack a real test run.

The Fabric Difference

These are made from 92% viscose derived from bamboo and 8% spandex, and the brand claims it is up to 4.5x more breathable than cotton. After a few wears, I noticed less sweating through the day, and the fabric genuinely feels softer against skin than a typical cotton blend.

Fit and Comfort

The extra-long 7.9 inch to 9.8 inch inseam (depending on size) actually stays put on the thigh instead of riding up, and the open-fly, seamless back design means no annoying tags or bunching. The elastic waistband is snug without digging in.

Pros: Breathable bamboo fabric, no-ride-up design, tagless comfort.
Cons: Runs true to size, so check the size chart if you're between sizes.

Current Deal

They're currently on sale at $39.99, down from $42.99. Grab the 3-pack here while the deal lasts.
