Editorial take

Designed for backpackers and mountain travelers needing dependable weather protection without carrying dead weight, this shell pant prioritizes fast deployment and packability. Built around a 2-layer Gore-Tex Paclite construction, it sheds driving rain and cuts alpine wind effectively while compressing down small enough to live unnoticed at the bottom of a pack until conditions turn foul.

The standout field feature is the generous three-quarter side zippers. They allow you to pull the pant on over muddy trail runners or bulky hiking boots without taking your footwear off on an exposed ridge. Cracking the zippers down from the top offers immediate mechanical venting when grinding uphill under a heavy load, significantly reducing the internal condensation buildup that typically plagues non-vented storm layers.

As with most Paclite garments, the interior surface can feel slightly clammy if worn directly over bare legs in humid weather, making light base layers or running shorts the best pairing underneath. The face fabric holds up fine against typical trail brush and campsite wear, though sustained scree sliding or sharp alpine rock requires caution. Compared to budget polyurethane shells, it justifies its tier through superior ventilation and proven weather resistance.

Best for

  • Three-season alpine backpacking
  • Wet-weather day hiking
  • Shoulder-season mountain travel
  • Emergency storm protection

Not ideal for

  • Paclite interior feels clammy directly against bare skin in warm rain
  • Face fabric requires care against sharp alpine rock and crampon snags
  • Noticeably more expensive than standard polyurethane rain pants
