Arc'teryx  Proton SL Insulated Hoody - Men's

I'm quite happy with the warmth and fit of this jacket; however, the logo is printed onto the material rather than stitched like many other Arc'teryx products. After just one wash (carefully following the care instructions), about two-thirds of the "ARC'TERYX" logo on the hood peeled off (see attached photo), which was really disappointing. Now I'm afraid to wash it again, worried that the chest logo might peel as well. Given that prices have been steadily rising, I hope Arc'teryx also focuses on improving the quality of their products. It's undeniable that consumers pay a premium for the brand name — and when the logo peels off, it feels like half the value is lost.

I got this jacket less than 2 years ago and mostly used it for hikes in chill weather. It's pretty comfortable and breathable which makes it a great alternative to the atom on warmer days. This winter i took it out for touring one day and once i got home i realised my backpack straps had all damaged the front of the jacket at waist level. I planned to used it for climbing this spring (as it is advertised) but i doubt it would fair well against a harness and rock. A bit of a mixed opinion on this one :(

I've been super impressed by the comfort and performance of the Proton Lightweight Hoody. Taken it climbing on multiple occasions and have been really satisfied with how it moves and stretches under a harness. Similarly, it breathes well once you start moving on the wall or on the approach. Hood fits over a helmet as well. The inner fleece lining is incredibly comfortable and feels great. Warm when you need it and breathes when you want it. Would definitely recommend to anyone looking for a good climbing garment to keep you comfortable while climbing at the Creek in the fall or Yosemite in the spring. It's held up surprisingly well through the past year. I'm 5'8" 140lbs and elected for a medium where as I wear a small in the Atom. Felt like a medium was more comfortable for climbing related pursuits.

[Employee of arcteryx] I’ve been waiting on this specific one to be my new go-to active midlayer jacket, and it didn’t disappoint. The materials and quality are on point, and it’s held up well on my recent hikes around the Squamish area. The hood feels a bit smaller than the one on my Atom (same size, Large), but the fit still works great. Also, I’m loving the Dynasty color — bold, clean, and looks even better in person.

The Proton SL Hoody is easily my favourite lightweight insulated jacket. I frequently use it for Ski Touring, Rock climbing, and alpine/ice climbing. It's warmth to weight ratio is hard to beat while still breathing well during higher output sessions. I recently did a winter ascent of Ledge Mountain above Squamish, BC which involved a biting wind, cold temps and even sun/warmth. I did not take the jacket off once which I think shows how versatile it is even in changing temps, conditions + stop and go aerobic/technical climbing. My only suggestion is that I would recommend going up a size as it fits a little small which makes it tough to fit other layers underneath. I am 5'9" and wear a size Mens Medium. I usually wear a Small.

Have had this jacket for 5-6 yrs and am very happy with its quality and performance. I use it primarily for day hikes in cool to cold weather and have used it couple hundred times. I’m 5’11” 175 and medium fits me well. Fitted but not tight. With temperatures in the 35-45 range I find myself wishing I had more insulation but after a few minutes exertion I’m comfortable. The exterior is quite durable and sheds dirt well. I’ve been wearing Arcteryx since 1999-2000 and have my share of their stuff but this and the kyanite hoody get the most use. I also love my Proton LT but generally to warm for it most of the year in Georgia.

This coat is absolutely incredible. I love the fit and feel of it, both inside and out. It looks great when you wear it, and it handles most movements without you even noticing you’re wearing it. It’s the perfect coat for mild to even colder outdoor activities. The front top pocket can hold a phone, and the lower pockets are great for resting your hands or keeping your keys, cards, or important items close at hand. Yes, this coat will be perfect under my Beta AR when the temperatures drop or the precipitation doesn’t stop. That aside, this jacket can be your go-to for everyday wear.

It is warmer and better than previously expected. First time I tried it in 15 degree Celsius (I'm living in Europe) in around 30 km/h wind with just a no name T shirt. I talked with my neighbour for an our and it was a little bit too warm. Next time I used with a merino baselayer in 9 degree Celsius in light rain and small wind. I drove car, went to shop and post office, so it was a normal daily use. I just shake off the rain drops from the jacket before got in the car. The jacket did an excellent job. I did not feel cold but I was not overheated when I was inseide.

The label came off after a month of use. Good layer for its intended use, but it's not very durable.

I got the Proton Lightweight hoody a few weeks ago. I’ve been wearing it during spring weather (sun, wind, dry and wet weather) with and without a Arc’teryx shell. I get warm fast with some fleece, but this jacket maximizes breath ability with out sacrificing warmth. Very practical pockets (sides pockets are línea with warm fleece). I like that it zips up high and the hood somewhat disappears when I’m not wearing it. Packs light so you can carry it anywhere. Great versatile piece for anytime (could easily replace your cotton hoodie)
