Up Jack

Rated 5.0 out of 5
Based on 7 reviews

$69.00 $129.00

Up for anything.

We needed a jacket for going up. Something to keep you comfortable while you’re walking uphill, no matter what kind of crazy mountain weather is happening. So we made the Up Jack. 

It cuts the wind, sheds moisture, and breaths like you’re wearing nothing at all. The soft, airy texture of our Japanese nylon never feels clammy, and has just enough stretch to flex to your every movement. You won't find a more comfortable solution for your uphill alpine adventures, nor will you find a jacket that you want to wear more. 

  • 100% Japanese nylon
  • 34 denier, air-textured ripstop
  • 100% windproof + water-resistant
  • PFC-free DWR coating
  • 1/2 zip for easy access + extra ventilation
  • Athletically articulated fit throughout
  • Raglan sleeves
  • Zippered chest pocket on the left side, which doubles as a storage bag
  • Large, double-entrance kangaroo pocket
  • Internal elastic on the hood for streamlined fitting under or over the helmet
  • Elastic wrist cuffs + hem details
  • Packs down the size of a tall boy! 
  • Weight: 6.7 oz (size Medium)

    We do our best to process and ship all orders within 1-2 business days, and we offer free exchanges + easy returns within a 30-day window.

    Versatile & Lite

    This is a great layer for any occasion when it's not super cold out. Packs up great too. The fit is definitely for men. I usually wear a women's large but had to get a small in this and I still roll up the sleeves.

    Good Skinning Layer

    This is a handy layer for skinning up as the name implies. It is light, packs down tiny, breathes well and repels snowfall. I wouldn't use it in drizzle. The kangaroo pocket is surprisingly handy for keeping things out of the snow during transitions. I wish it was offered in other colors.

    My favorite layer to bring on every adventure!

    This is a solid item to have in your backcountry pack or to use on a warm resort day. i also use it when cycling or running or doing other sports in colder weather

    My ride or die.

    I live in this and I love it! I originally bought it for touring on warmer days, but now rock it when I am mountain biking, hiking, or just about anytime I need a light, windproof layer. I wouldn't suggest this as a rain jacket, but it does a pretty great job keeping me dry in light rain or drizzles. I usually wear a size M in women's jackets, and got the Men's S/Women's M size in this for a slightly larger fit. I could probably wear the size down comfortably, but I do prefer the relaxed fit.

    Going up!

    Love this layer for going uphill when I don’t want an outer shell, breaking trail and trying to keep the ‘heat’ from building up too much, etc. Great new piece to the kit.
