Numb legs just dropped off your excuse list for not summiting.

When it gets super cold on your alpine climb or right before your summit push, let the Patagonia Men's DAS Insulated Pant boost your confidence. The PrimaLoft One is Patagonia's ultimate insulation made for extreme warmth even when wet so those extended belay sessions won't seem so brutally cold. Its highly compressible insulation and its lightweight yet durable nylon ripstop shell make this pant extremely convenient to bring with you no matter how light you want to travel. And the elasticized waist and mini-gaiter cuffs allow quick and easy on and off possibilities without losing necessary warmth.

  • Nylon ripstop shell is lightweight, highly water-resistant, windproof, and durable to keep you ascending without worry
  • 100g PrimaLoft One polyester insulation is water-resistant and highly compressible so you don't have to sacrifice warmth for space
  • DWR (durable water repellent) treated to keep you dry at the last push up the peak
  • A sculpted regular fit sized as an over-pant will help maximize your warmth potential
  • Elasticized waist with hook-and-loop tab adjustments and the full-length, two-way side-zips with snap closures allow quick and easy on and off capabilities and venting when needed
  • Elasticized mini-gaiter cuffs with snap tab closures can accommodate alpine boots and keep heat in

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

These pants are super warm and relatively lightweight. I brought them with me on a yurt trip to Montana and this was perhaps the most important piece of clothing I brought. On super cold nights these kept me comfortably warm! If you are going to be in extremely cold situations, I highly recommend getting a pair of these. The DWR coating keeps them semi-waterproof and since it uses synthetic insulation (not down) it still maintains its insulating properties if they get a little wet in the snow.

Winter cragging heaven

  • Familiarity: I've put it through the wringer

If you crag all winter long, these should definitely be in your kit. Its amazing how much more pleasant they make the day - just buy a size that fits a little big and pull them on over your harness, leaving the fly unzipped for the belay loop.
