Hood isn’t a real hood

6 years ago
I never buy a jacket without a hood. I must say I’m quite disappointed to buy a jacket that says it has a good only to find out it has a 0.5mm think bit of nylon that you can pull over your head which offers zero insulation. Waste of money, have to buy another jacket now to try to get one with a real hood.
Proslightweight good fit
Consnot windproof, hood isn’t a real hood

No, I do not recommend this product.

Hi Michael, Thank you for providing your feedback. Many individuals throughout the company read these reviews, and changes are sometimes made to products as a result, so we appreciate when our customers take the time to let us know what they think. The idea behind the Proton FL is to have a very light, air permeable mid-layer or stand alone piece. It is meant to pack small and the hood is designed this way to reduce bulk. Kindly,

Great jacket

6 years ago
Wore it hiking in 40 degree (F) temperatures and it was perfect with only a thin base layer when moving rapidly. Jacket breathed well in high output activity and didn't overheat. The snug fitting hood is a plus. Also very comfortable and I wear it after workouts or activity when cooling down. Great alternative to proton LT hoody (which I also love) in more moderate temps.
Q: Activity
A: hiking
Prosgreat hood, well designed jacket

Yes, I recommend this product.

Best piece of clothing I've ever owned

6 years ago
I love this jacket! It's one of the most impressive pieces of clothing I've ever owned. I bought it mostly for fall/spring hiking and as an insulating layer for the tail end of winter. Much to my surprise, when I decided to test its limits it kept me warm during a 20 minute moderately paced walk in roughly -12 celsius temperatures, layered under a rain jacket (2 layer DryVent) and over a t-shirt. I do run on the hot side though. The fabric is amazingly comfortable but feels substantial enough to be durable, a key factor in my selecting this over the Atom SL. Other key factors in that decision were the chest pockets and hood. The hood contours the face much better than the Atom SL (think more like a non-insulated version of the Atom LT). The wind resistance isn't great, but that's not a deal-breaker at all because of the temperatures I'll be wearing it at. One last thing to note is that I typically wear a medium (in say, the Proton LT or Atom LT) but with the FL I found myself between medium and small. I chose small because I preferred the snug fit and I don't plan to really layer underneath it. All in all, I would highly recommend it for anyone looking for a lightly insulated, highly breathable jacket.
Q: Activity
A: Hiking, walking
Proslightweight, breathable, warmer than expected, looks great, super comfortable
Consnot very wind resistant

Yes, I recommend this product.
