My go-to jacket
2 months 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 transition layer

Just the right insulation for spring / fall hikes when you need some insulation but also breathability. Loved taking this jacket on many hikes when I needed an extra layer. It is a trim fit so it fits quite cozy close to the body.

Lightweight and so breathable!
6 months ago
It's an absolute winner! The fit is spot on, incredibly light, and highly breathable—perfect for all kinds of activities. It offers great water resistance with its DWR finish, works as a solid windbreaker, and layers effortlessly. Definitely a piece I’d buy again!

Light compact and warm.

Fits true to size. Very warm for its weight and compactness. Great as a light warm casual layer as well as an active layer for colder ski touring days. Very versatile

New favourite!

I run hot all the time and it’s so hard for me to find a jacket that I can wear on cooler evenings or early mornings whereby I don’t begin to sweat. The Proton is an excellent weighted jacket. I love the thin waffle fleece on the inside- it helps add a little bit more insulation without it being too heavy. Works great for higher output activities for me too. I love the phosphorescent colour too!- so much fun and different. Size wise I am usually an L, but I went for the XL just for it to be a more oversize fit which I like. Also used it recently to wear on an early morning canoe trip, it ended up getting quite wet but dried pretty quickly. I also like that I can just throw it in the washing machine and tumble dry it and it’s good to go!

Runs small

Very nice jacket. Light weight and warmth for mid-40’s weather. Size up if you plan to layer over long sleeve tops as armholes are a bit tight. My other pieces from the same line of the same size are less snug. Minus one star for the zipper. It consistently catches the bumpy seam between neck line and hood panels. Could be fabric or workmanship issues. Run the zipper up and down a few times to test for smoothness before you buy.

Great Layer!
3 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.

UNICORN PIECE
6 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. :)

One Jacket to Rule all Jackets
5 months ago
There are no negatives. It’s light, but warm. The fit is amazing. Chest pocket big enough to hold a phone. Breathable. Feels and fits the same as my proton vest and proton hoody — please keep making Protons (and with more colours!). Perfection in jacket form.

Amazing lightweight warm hoody
1 month ago
At first I was unsure this jacket would be warm enough given how lightweight it was, but it's the absolute perfect temperature. I wore it at nights while camping and was toasty. Easily compactable and super lightweight.
