Ryan Andersonwrote a review of Arc'teryx Proton LT Hooded Insulated Jacket - Men's on October 30, 2019
Familiarity: I've used it several times
Fit: True to size
I think that a lot of people are looking for a unicorn jacket. One jacket that can conquer all situations. Those jackets are so hard to find because they usually are mediocre in all categories. Instead of stellar in a few. This jacket isn't a unicorn, it isn't going to be the only jacket you will ever need. But it will help fill a lot of gaps in your quiver of jackets. The purpose of this jacket is to provide warmth while stationary, and breathability while doing highly aerobic exercises. It will shed light rain and snow but it isn't going to be your outer layer while in a blizzard.
The cut of this jacket is slim, which works great for layering. The hood is nice and big. The front of the jacket is short, which is similar to other Arc'teryx jackets.
I would compare this jacket to the Arc'teryx Atom LT or the Patagonia Nano Air. The biggest difference is that the Proton LT is more durable, with a different face fabric and is much more breathable.
