    Patagonia High Alpine Kit: Nano-Air Light Hoody and Pant

    Kevin GloverBy Kevin GloverNovember 16, 20166 Comments6 Mins Read

    Patagonia‘s new High Alpine Kit is generating a ton of buzz and excitement. I don’t normally buy into brand hype, but I’m genuinely excited by what this collection of gear has to offer. It’s one of the first precisely curated product groups for alpinism. I say ‘precisely curated’ because there are plenty of other brands who offer a complete set of alpine kit, but what I like about the High Alpine Kit is that it takes the guesswork out of buying gear. Each piece is carefully designed to fulfill its function while working smoothly with each other piece. The result is a tightly knit experience for climbers and outdoorsy folks of all stripes.

    Patagonia High Alpine Kit Features:

    • Light, yet durable 100% nylon ripstop shell and plain-weave liner offer generous mechanical stretch and exceptional breathability, with a DWR (durable water repellent) finish
    • Using a new 40-g weight, our revolutionary FullRange™ insulation warms and stretches; combined with the shell and liner, this creates a hoody and pants with excellent mechanical stretch and unprecedented air permeability (70CFM)
    • Engineered pattern eliminates all seaming across the shoulders and back, eliminating abrasion points and enhancing unprecedented stretch
    • Stretchy hood with binding easily pulls on or off, even when jacket is zipped
    • Pants feature elasticized waist for easy pull-on
    • Pullover silhouette has deep center-front zipper to allow for quick venting and easy on-off
    • Pants feature two-way head-to-head full-crotch zipper for quick pit stops
    • Exterior left-chest zippered pocket
    • Stretch-woven on cuffs is shaped, patterned and seamed to reduce bulk when layered and push up easily without constricting forearms
    • Shell: 1.6-oz 30-denier 100% nylon stretch ripstop. Lining: 2-oz 50-denier 100% nylon stretch plain weave. Cuff: 4.7-oz 88% polyester/12% spandex stretch-woven. All fabrics with a DWR (durable water repellent) finish. Insulation: 40-g FullRange™ 100% polyester stretch insulation
    • 309 g (10.9 oz) top; 266 g (9.4 oz) bottom
    • MSRP: $249 (top); $149 (bottom)
    Patagonia High Alpine Kit: Nano Air Lite Hoody and Pant
    A little Rainier action

    Nano-Air may be the best active insulator

    The Patagonia Nano-Air Light Hoody and Pant are part of a genre of gear known as ‘active insulators.’ The idea here is that the insulation will be able to adapt to both high and low output moments within an activity. For example, you can climb while wearing the Nano-Air Light Hoody and then stop for a belay without having to alter your layering system to deal with sweat. They’re meant to breathe extremely well without sacrificing static insulation. That dual ambition is the gold standard for active insulators.

    I have had an absolute blast testing the Nano-Air Light Hoody and Pants. For one thing, I’m a naturally very warm person. I sweat easily and profusely and so I often wind up having to climb in layers that don’t protect me well from the wind for the sake of avoiding extreme sweatiness. Take special note of the ‘Light’ appended to the Nano-Air label; these two products are both designed to be a trifle more svelte, with a lighter g/cubic meter insulation weight. It’s roughly 1/3 lighter than the traditional Nano-Air, and it’s noticeably more breathable. Patagonia’s proprietary FullRange insulation truly feels like a cloud – it moves, breathes and stretches with you.

    The cuffs are magic!

    Like I said, I had a hoot testing these two products. They’ve been everywhere from the top of Rainier to rainy creeksides in the Enchantments. I can say unequivocally that these are the best ‘active insulators’ I’ve tested. One feature that is shared between both the Hoody and the Pants are the cuffs. These are carefully designed to slide easily underneath upper layers while still pushing up easily to vent heat. They’re quite trim, mind you, and many mountaineers will likely find that their calves are too big for the cuffs to be comfortable. It’s also probably true that each piece runs true to size for an alpine fit, or just slightly small overall. For reference, I’m 5’11”, 180 lbs. with a 32″ waist and tested a Medium in both tops and bottoms.

    I absolutely dig the color scheme

    The Hoody has several points to note. For one, the hood is very well designed and can go either over or under a helmet – unless it’s a particularly bulky helmet. It’s stretchy and slides off and on easily, even when the Hoody is fully zipped. It’s a pullover, mind you, so it’s not a full zipper. But it is an especially deep zipper, reaching way down on the ribcage, so that the jacket is easy to get on and off and lets you dump heat efficiently. There’s also a pretty generous chest pocket. Plus, the black version has some epic retro color schemes, pairing orange, purple and blue.

    The softest waistband you’ll ever feel

    The Pants have interesting features, too. Chief among them is the full zipper running from the front to the back of the crotch. The idea here is obviously to allow a full-service pit stop without removing the pants, should the need arise. This is facilitated by head-to-head two-way zippers that run smoothly along the narrow zipper track. There’s also a draft tube along the whole zipper. I’ll be honest, I expected the zipper to chafe like crazy if you were to hike an extended period in the pants. However, I hiked seven miles on a cold fall day and felt great. Who would have expected? Plus, I pushed the cuffs up and they stayed the whole time. I was very impressed.

    For those unexpected alpine stops

    The Good 

    • Excellent performance overall – breathes, moves and insulates well
    • All zippers slide smoothly and easily
    • Excellent cuff design and construction
    • Pullover’s hood is adaptable and comes on and off easily
    • Fairly high-denier fabric is durable

    The Bad

    • Cuffs on the pants are small and hard to get over your calf

    The Bottom Line: Patagonia High Alpine Kit

    These are two of the best products I’ve tested. They’re both so simple and well designed that there’s almost nothing to nit pick at, and the few things that I expected to be an issue didn’t actually materialize. If you’re looking for a very light active insulator, you can’t get better than the Nano-Air Light products.

      A few years down the road – I was wondering when you mentioned the trim fit – if you were to have your own would you go with the Medium or the Large size Nano Air Light Hoody? How tight/trim was the Medium for you? Could you have fit an extra lightweight fleece underneath if you needed extra insulation?

        Hey Jono,

        Thanks for writing. It’s amazing the interest this piece still garners. For my frame, I wouldn’t have comfortably been able to fit a fleece under the Medium. I also run hot, so I’d be using the Nano-Air more like a breathable performance fleece to start with. If I could go back, I would have gotten it in Large for my 5’11”, 200lb frame.

      Thanks for replying!
      At 5’11, 200lb I’m surprised the medium fit! What aspects of the medium worked for you?
      And would you think if I’m a fair bit lighter – would the medium be a good fit for me or would you suggest going for the large?

        You bet! And sure. The medium was trim and honestly I might have been a little slimmer when I was wearing this a lot since I was working as a guide. I can’t recall super well, to be honest. But the torso and arms are both quite trim which was great for putting under a shell. A smaller person definitely might be able to tuck a light fleece under it without any issues.
