    Proton LT Hooded Insulated Jacket

    Noticing that most "breathable" insulated jackets don't actually breathe that well during fast-paced activity, Arc'teryx designed the Proton LT Hooded Insulated Jacket for high-output alpine missions where thermoregulation is key to completing your lofty objectives. Instead of being merely breathable, the Proton LT's face fabric and insulation are air permeable, meaning the jacket allows rapid air exchange without relying on built-up pressure to expel condensed perspiration along the inside of the shell. Ultimately, this means you'll stay pleasantly dry from the inside-out. Additionally, Arc'teryx gave the Proton a climbing-specific cut with a slim fit that reduces needless bulk while articulated arms and gusseted elbows enhance mobility.

    • Breathable, warm, and durable jacket for high output activities
    • Durable, weather-resistant fabric protects against the elements
    • Air permeable insulation regulates a comfortable micro climate
    • Helmet compatible hood is insulated for warmth in cold temps
    • No Slip Zip prevents front zipper from self-opening during activity
    • Insulated hand pockets warm cold fingers during rest breaks
    • Dual hem adjustments help seal out gusts in adverse conditions
    • Slim fit allows freedom of movement and comfortable layering
    • Item #ARC00ZO

    She Didn't Want to give it up

    • Familiarity: I've used it several times
    • Fit: True to size
    • Size Bought: Small
    • Height: 5'4"
    • Weight: 115lbs

    My partner demo'ed this jacket for a couple weeks in late fall/early winter and she did not want to give it back at the end of the demo. She absolutely loved it and will likely end up being an Xmas present for her.

    The fit, breath-ability, and versatility were all dialed in. She loved it for chilly hikes/runs, for going to dinner and breweries, and even for wearing in our drafty house. We got drizzled on at the dog park in about 35F weather, and this thing kept her warm and cozy!

    Jacket with Many Uses!

    • Familiarity: I've used it several times
    • Fit: True to size
    • Size Bought: Medium
    • Height: 5'6"
    • Weight: 130lbs

    Whoa. This jacket really can do it all!

    First off, the sizing is really true to size. I am usually a Medium in most jackets and found that to be true here as well!

    I love how lightweight this jacket is, while still being pretty warm! In temperatures of 30 degrees F or warmer I would say it is good to go all on it's own, but below that I'd also add a shell!

    My favorite spec of the jacket is how quick drying and breathable it is! Getting a little sweaty while working hard is inevitable, but this jacket breathes so well and evaporates any moisture very quickly, especially for an insulating layer

    10/10 would recommend!

    Finally!

    • Familiarity: I've used it once or twice and have initial impressions
    • Fit: True to size
    • Size Bought: medium
    • Height: 5'8"
    • Weight: 135lbs

    I've wanted this jacket for so long! Stoked to finally have it.

    My initial report is on the sizing. I am normally a medium and love that size for me, in this jacket. I'm 5'8 and about 130lbs with athletic shoulders.

    Full disclosure, I'm a wimp with the cold! It's been warm for sure and great as a stand alone in 40F+ temps, though. Under that, it gets a little chilly after about 20 minutes outside and needs a shell.

    I will update this review as I use it more. Can't wait for the winter season to fully drop!

    Love the Brand

    • Familiarity: I've used it several times
    • Fit: True to size
    • Size Bought: x-small
    • Height: 5'3"
    • Weight: 135lbs

    My first experience with Arc'teryx was on a cliff ledge at Indian Creek in October, it was cloudy and windy and I was super cold, when someone let me borrow their jacket while they climbed. I have never been so grateful. SO WARM. So I got Arc'teryx Proton LT Hooded Insulated Jacket - Women's XSmall. Its definitely the lighter version but equivalent to what I needed. Still warm for fall weather, stretchy, nice tight cuffs.Its slim on the body but not tight in the shoulders.I have a dog and I dragged it around in the desert so its pretty sturdy. Good for layers. Loved that it zipped to the nose and could pull the hood up. Pockets on the hip and a big phone size chest pocket, yeah! I'm petite and usually there is extra on the length and arms, it was perfect.

    Do-it-all jacket!

    • Familiarity: I've used it several times
    • Fit: True to size
    • Size Bought: XS
    • Height: 5'2"
    • Weight: 125lbs

    I love this jacket! Arc'teryx has designed a wonderfully warm and functional jacket that you can take on all your adventures, no matter how big or small. This jacket is great for everyday use in brisk or chilly temps, but will keep you toasty in the mountains when you're exerting yourself too.

    The fit is very flattering and is trimmed to fit the body; great as a midlayer that insulates and breathes at the same time. If you're looking for a snugger fit , I would recommend sizing down. I'm usually a small but ended up getting an XS because I wanted to layer over top of it and was looking for a slimmer fit.

    I never over-heat in this jacket, but it keeps me warm in a wide range of temperatures. Great to take with you climbing, hiking, snowshoeing, or bopping around town... it will become your go-to choice year round, since it offers warmth and style, all in one. Can't recommend it enough!

    Light and Warm

    • Familiarity: I've used it several times
    • Fit: True to size
    • Size Bought: Medium
    • Height: 5'2"
    • Weight: 145lbs

    The proton LT model is an amazing jacket! It keeps you warm but breathes so you do not overheat when outdoors and hiking between the sun and shade. It is wonderfully packable and great as a mid-layer, as it is not waterproof. My only complaint about this is not only on this model but other Arcteryx items as well as the length of the arms, they are too long for me all around so the bunch up a bit at the ends. The fit of the jacket itself is spot on. I would definitely invest in one of these if you are into active pursuits!

    Mountain Powerhouse!

    • Fit: True to size

    The Proton LT is a really comfortable, warm, and breathable jacket meant for virtually any cold-weather mountain activity. I like to think of it as a warmer, more breathable, and more packable Atom LT. You still get the comfort and softness you love with the Atom, but both the interior lining and exterior fabric are both air-permeable. It also has strategically placed 80 and 60 grams of Coreloft Compact Insulation. It is durable enough to handle anything the backcountry can throw at it and because it is so breathable, it is incredibly versatile. The fit is trim, but true to size. Similar fit to the Atom line but slightly longer in the back.
