I found these to be quite comfortable, breathable, and cool compared to other underwear. I purchased two pair as a trial, and ended up getting two more from a different vendor.

I've noticed one thing since my initial review. The waistband from one vendor has drastically less stretch than a pair from another, which makes them less comfortable.

After a little research I've found, that the products that are shown where the blank space in between the logos on the waistband is centered in front(as with this vendor), these are the ones that have very little stretch in the waist band.

I've purchased this product from another vendor, where the logo is centered in front. These are the ones to look for if you want to take the time.
