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

  • Air permeable insulation regulates a comfortable micro climate

  • Dual hem adjustments help seal out gusts in adverse conditions

  • Item #ARC00ZO

I really wanted to love this jacket. I never spend a lot of money on gear but I love Arc'teryx look and decided to give it a shot. Quite disappointed for the price. This jacket is either too warm or too drafty. I get cold in it on a windy day, and had to take it off on most hikes in the spring because it would not breath well and I would overheat on steep hikes. I give it a 3 but only for the looks and weight. As much as performance, my other cheaper jackets from other brands worked much better so far.

This jacket has been great for so much of the year! It is low bulk but seems to keep me so warm! As with any Arcteryx item, the quality is amazing and every feature is so thoughtfully put together. This has been a great jacket to wear in the fall on those chilly days. Or in the winter when I am just outside briefly and do not want to bulk up with a big outer jacket. I really like it because I get cold pretty often and this is a great, casual looking light jacket that keeps me way warmer than one would expect. I like my jackets to fit a bit snugger. Could have squeezed into the xs, but went with the small. Would size up if I wanted to heavily layer underneath.

She Didn't Want to give it up

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!

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!

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!
