Best lightweight insulation piece ever

2 months ago
The best lightweight insulation piece Arc'teryx makes. This is my go-to jacket for most of the year. Super breathable, very abrasion resistant, looks great, lots of pockets, soft on the inside, nice stretch, warm when it counts. The new update also brings some improvement with stitched logos and improved cuffs and cut. Awesome piece, would highly recommend for climbing, hiking, around-town, basically anything.

    My Go-To Midlayer

    2 months ago
    The absolute GOAT of high-output midlayers. I bring my proton SL EVERYWHERE, regardless of what I am doing. I am on my snowboard 50-60 days a year, and this bad boy is money underneath a shell in the -5 to -15 range (especially if you run warm). Perfect mix of breathability & lightweight warmth, the Octaloft is also incredibly cozy! I like to size up for extra mobility, it also has a bit of stretch that helps.

      Just what I was looking for. Great looks, extremely comfortable, warm. Could breathe better. Works well as mid layer or outer layer in temperate conditions.

        Another really nice piece by Arcteryx

        4 months ago
        I already have the atom jacket and wanted something a little lighter weight, a little more breathable and a little more 3 season specific while maintaining a great fit and good mobility. This jacket ticks the boxes and is exactly what I was after. Really nice piece with thoughtful construction and the ability to be used in 4 seasons. Perfect for travel and activity. A nice light insulation layer helps with warmth while not being too bulky.

          Great jacket, breathable with light insulation.

          4 months ago
          Breathable and lightweight jacket with octa loft insulation. Perfect for high output activities in colder weather. Very good breathability. I use this for trailrunning and hiking in the spring and autumn. The 2025 edition has embroidered logos. I would rate the sizing as normal, it´s slightly larger my 2022 Proton FL hoody. I first bought an XXL, but I had to size down to XL.

            Proton SL Hoody Men's

            The lightest, most breathable option in our Insulation Collection, the Proton SL Hoody takes the guesswork out of warming up on cold climbs and other high-output activities in cool conditions. The knit insulation holds its loft and shape—no matter how often you stuff it into the bottom of your pack. More importantly, it allows your body to breathe, so you’re not left a sweaty mess after you have to step on the gas to get through the crux.

            What's been updated: Updated with recycled Fortius™ fabric for improved durability, and chest pocket and design lines that align with the Proton Collection.

            Need a heavier option? Try the Proton Hoody.
