Disappointment, cheap, not worth the money

a month ago
It’s a waste of money. I bought this not only for the product but the brand. “Arc’teryx” is renowned for their quality products and warranties but they aren’t what they once were. I have multiple Arc’teryx products and my proton coat disintegrated. The fabric is poor quality , I can’t believe it’s even advertised as “climbing and high output activities” it’s destroyed and I wore it to the grocery store! I emailed Arc’teryx about issues and they refused to honour their warranty on the fabric. The material literally rips apart under any strain. The main zipper split after 1 year and both pocket zipper broke shortly after. Unless their quality dramatically improves it’s not worth the price. Do better Arc’teryx.
Q: Pros:
A: Warm
Q: Cons:
A: Poor quality
I use this product for:Casual Wear

No, I do not recommend this product.

Go to Snow Midlayer

2 months ago
I love this as a midlayer for winter hiking, snowboarding and splitboarding. It's really breathable which helps maintain a comfortable temperature- I tour/hike fast (no talking or stopping!) It's a warmer layer, so will pair with the Satoro Merino Crew in cold weather -8 to 0*, and the Lana long sleeve for warmer temps. I've worn consistently for two seasons (120+ days) and have had no pilling. My only con is if you sweat needs a strong detergent as it holds onto smells (as I find most synthetic fabrics do (I have a sensitive nose.)

Possibly less durable fabric

4 months ago
Love this jacket for the fact it’s essential the atom jacket with an additional pocket, however it’s already snagged somehow in 2 small spots and I haven’t even had it 6 months. I paid full price for it too. A previous atom jacket I had has last YEARS with heavy backpacking and bushwhacking/ route finding in BC and somehow never managed to get a single hole in the fabric. I’m not sure if the fabric is a worse choice or if the quality over all has changed.

Hello there, thank you for sharing your feedback! We're glad to hear you love the design and functionality of the Proton Hoody, but we're sorry to hear about the snagging issue you've experienced.

This! ⬆️ the fabric is garbage and will be destroyed under any strain. I raised my arm and the sleeve ripped. It’s poor quality and the brand won’t stand behind their products. Move on buy something else.

New Fave!

4 months ago
Love this hoody - not too tight, not too loose, stretchy, light, and super cozy and warm. Light weight enough to layer with, warm enough to wear on it's own. An all round great piece that is super versatile, functional, and looks pretty darn goo too.

Such a great fitting jacket!

4 months ago
This jacket is EXCELLENT! I got the Interstellar color and it's gorgeous. I also own a couple of Atom's jacket and this one fits my body type better. I feel like the new Atom fit is a bit boxy and long. The Proton is more fitted for a woman's body and it's the exact appropriate length (not too long, not too short), it sits right above the widest part of my hips as it should (I have a long torso). Consequently, it doesn't ride up when exercising, running, hiking, etc. The comfort and versatility of this jacket is incredible... I use it for everything!
