Great fit, bad quality

  • Familiarity: I've used it several times
  • Fit: True to size
  • Size Bought: Medium

Fits true to size. I’m a small/medium (5’6” & 140-145lbs) in most underwear and the medium fit has a very comfortable relaxed and non snug fit. I really like the fit, but super disappointed that after about 4-5 wears and washes (on gentle and never dried), the seams on 2 separate pairs of these started to unravel. And the material has what looks like vertical pantyhose runs from seam to seam where it unravels, so I can’t even mend them. I bought a similar versions in IceBreaker over a year before these, wore them nonstop on long treks and climbs (up Fuji, Kilimanjaro, Meru, etc.) and those have held up perfectly. Hopefully the quality improves, they’re too expensive to just be disposable underwear.
