I'm impressed with the quality and durability, but they are warm.

I'm lovin' 'em. I have already used merino boxer briefs and loved them, so I was happy to see these on SAC for warmer weather when I didn't want so much coverage. Great next-to-skin comfort with all the benefits of merino underwear and cooler because of the cut. They run true to size.

Looks like these are being phased out? I hope not. Terrific product and I hope Backcountry.com will continue to carry, Smartwool will continue to manufacture, etc.

Out of all the brands and types of brief underwear, these are the best I have tried. They are light, comfortable, and dry the fastest of any I have. If they weren't so expensive, I would buy more. Thats the only reason for four stars.
