These were a life saver! I was able to hand wash and let dry over night. Kept everything cool, dry and comfortable while my riding partner that used synthetics didn't have the same experience.

I love the fit and the comfortability of this underwear. I really like the lined waistband. I would like to see a thermal version with 100% merino .

hey tend to bunch up on the thigh, and the fabric feels loose even though the waistband is tight enough.

Love the material and waistband but the fit feels very baggy for active style undies probably will try a size smaller but I'm worried the waist would be small.

Paid a lot for three boxers I bought three in December 2024. Of the three, part of a rotation of 14 boxers, all three did not survive. -1x broken elastic -2x stitching that deteriorated These were the last boxers I bought, and my previous ones from a different material and brand lasted longer... Not worth the price paid.

I used these briefs whilst hiking two long Caminos. They held up very well, even through a number of washes. So I bought some more for my regular hikes at home.

Good as per my expectation. I was looking for something to keep things thigh while riding long days on the saddle. They seem to loosen up after 4-5 hours and does not offer the support I was looking for those long distance travelled. overall great boxer, maybe not for cycling.
