Crazy Idea Nitro Jacket


The Nitro is a lightweight ski mountaineering jacket made with breathable Crazy Endurance fabric. That means it’s also abrasion resistant and repels dirt and water. Just what you want in a jacket for ill-defined mountain adventures. The Nitro has an ergonomic cut and the fabric is stretch woven so it won’t inhibit your progress. The jacket has modern Italian styling and matching function. Two hand pockets hold your things while schussing down the mountain. A comfortable hood gives the option of trapping some heat, or dumping it when the sun comes out on a long climb. Crazy Idea finished the Nitro with sealed YKK zips and cool reflective inserts. Turn on your Nitro boosters this season.

  • Crazy Endurance fabric is a stretchy, breathable softshell.
  • Central opening zip is backed with a protective underflap.
  • Two zipped hand-warmer pockets are in the right place.
  • Bluesign® approved fabric means it’s environment-friendly.
  • YKK zips form a good seal to keep out the elements.

Questions & Reviews

TSB (used product regularly)
My obsession with Crazy Idea products began with the Century pants (two pairs, hundreds of days of wear) and so I picked up the Nitro as an extra midlayer, mostly for deep winter touring. As with the meticulous, ski touring-specific design of the Century pants, the Nitro is tailored to the sort of movement you make during high output tours, with significant slimming toward the waist (doesn't move around under a pack hipbelt) and more space in the shoulders/sleeves for high pole plants. The breathability is excellent and waterproofing is decent -- plenty for light snow but not a great choice for powder days. Only quibble is that the underarm area is super tight on this jacket and creates a significant amount of chafing/rubbing during longer days. I'm thinking about cutting a gusset to give the area some more room because I would love to keep using the jacket. I'm 6'3" 185 and went for a size L, which fits great apart from the armpit area. PS as with all Crazy Idea stuff, this is way more stylish and has a more flattering (aka Italian) cut than your average ski touring wear (so long as you can overlook the funky contrast panel stitching!)

After about 10 days in the Nitro Jacket, it has become my go-to piece. The breathability combined with perceived durability should make it a regular in my fall-spring wardrobe. I'm 5'10" 135 and decide to go with the medium, since I have rock climber lats. This was a good call. I can still get a heavy fleece on to layer, but it isn't too baggy when I'm just wearing a single layer underneath. For the price, I think it's a great value. The fabric is quiet and supple. I also really like the black center for warming up my core on cold days in the sun. I used it one day in driving snow and stayed dry.

I forgot to say, the lower part of this jacket does feel slightly baggy, but after sticking my skins inside, I'm really glad it's there, otherwise, it would be way too tight. I'll take this to be part of the design. Good design makes for good performance.
