My go-to jacket

24 days ago
This is the best light and very breathable jacket. Probably the best cross country skiing and touring jacket I have in my collection. I wish they make it in more colours. I am waiting for some vibrant reds or yellows. I have this jacket in light brownish ochre colour and I love it. But I would like to change it up sometimes. Bottom line: I highly recommend this jacket. It is my go-to item in winter.

Great Layer!

2 months ago
The first time I used this jacket was on a ski traverse in the coast mountains. I wore it as a midlayer, over a merino baselayer. It was the perfect layer for this trip! It kept me warm and protected from the wind. The insulation was soft against my body and the right degree of warmth. The chest pocket was perfect for phone / snacks.

Hi there. Thanks for your feedback on the Proton SL Hoody. We're glad to hear you find it comfortable, but we're sorry the fit didn’t meet your expectations. The Proton SL is designed with a trim fit for efficient layering and movement, which can feel snug or shorter through the body for some. As an alternative, we recommend looking at the Atom SL Hoody. That being said, we’ll make sure to pass your comments along to our design team as we continue to refine our fits.

UNICORN PIECE

4 months ago
This is the unicorn of jackets and I wear it all the time. ALL THE TIME. It is my go to piece for AT, running, hiking, cross country, any high output activity in the winter where I need a little warmth and some breathability. Any time I wear it, which is all the time, the people I am with comment on how awesome it is. Other companies have started to do their own versions, but this is the best. The weight is perfect, the warmth is always good, from 0 to 40 degrees F. And I just vary what I layer with (a t-shirt or long sleeve in merino or tech material), and it's awesome. The fit is great, I am usually a small and the small fits well. I have two because i wear it so often and needed to work more colors in. My older one is from 2020, and it has held up to constant wear, the fabric has withstood a lot of wildnerness and doesn't have a rip or tear. I don't notice a huge difference in fit between the two, as other reviewers have suggested. I have the Atom, and I love that too, but if you're buying one, this is the one. :)

Proton SL Hoody Women'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 Fortiusâ„¢ fabric for improved durability, and chest pocket and design lines that align with the Proton Collection.

Need a heavier option? Try the Proton Hoody.
