    I miss the old version

    • Familiarity: I've used it once or twice and have initial impressions
    • Fit: Runs small
    • Height: 6'3"
    • Weight: 205lbs

    I had 8 pairs of the old version and LOVED them. Soft but supportive, not too tight, not too loose. The new version has an extra thick waistband that is way tighter than the last version. I tried sizing up but it was still uncomfortable. Disappointed.

    Overall comfy

    • Familiarity: I've used it once or twice and have initial impressions
    • Fit: True to size
    • Size Bought: Medium
    • Height: 5'11"
    • Weight: 145lbs

    Overall comfy, perfect fly, not too much pressure around the legs, it's actually kinda of loose, which I find to be perfect.

    Why change a good thing?

      The old version of these were great. Wore them pretty much exclusively for years and only recently did two pairs rip. Bought 4 pairs of the new one expecting the same thing. New waistband is much higher and about double the thickness (and way too tight) and the general fit is much tighter. The inseam also feels shorter. Will be returning.

      Just okay

      • Familiarity: I've used it several times
      • Fit: True to size
      • Size Bought: Large
      • Height: 5'10"
      • Weight: 175lbs

      I purchased these to test out as another option over the ExOfficio Give-N-Go boxer that I use heavily. The smartwool seems to be of good construction, but the sizing was a little off for me. The waist didn't have too much stretch, so I had to up-size to a large over my normal mediums. The large fits my waist, but the leg openings stretched out after the first day. They seem to tighten up with washing, but I prefer a brand that keeps it's shape over a longer duration. They work as a one day wear, but not as good as a several day item.

      Great outdoor baselayer

      • Familiarity: I've put it through the wringer
      • Fit: True to size

      I have worn these on everything from long freezing alpine climbing routes to short hard sport climbing routes in the summer, and I love them so much I even do my trail running with them now. Great adaptability to multiple weather conditions, good moisture control, good durability, great fit, and great comfort make these my favorite baselayer for just about every activity (and I use the long version for ice climbing and skiing in the coldest conditions). I think the sizing is listed fairly accurately but if anything these tend to be slightly smaller than the size (i.e., I have a bit thicker thighs than the skinny runner type legs and I wear 32 pants and the medium size fits great, barely snug but in a comfortable way, as underwear should).
