Let me down
Reviewed By Harriet, 07 Oct 2014

This jacket has done all it says on the tin...until a 90 km ultra I entered in August in the Peak District. Yes, the weather conditions were vile- pouring rain and howling wind all through the night. My attempt finished after 10 hours, when I passed out at a checkpoint. Upon peeling off the jacket, my baselayer underneath was damp through. I think I had spent several hours being cold and clammy.

I think it's up to the job if you want to use it in not quite such "extreme" weather conditions, but I wouldn't recommend it if you like going off and doing nutty things in awful weather for hours and hours.

I do feel a bit let down- I would have expected a "£220" (I got it on special offer a couple of years ago) to do a better job of keeping me dry.

Just to note: the pavement survived the encounter unscathed ;)



Great jacket for all the year round use.

Best membrane for fast paced activities
Reviewed By Sandra, 17 Jan 2013

The firefox is overall an extraordinary jacket. Great looks combined with Gore's new active shell membrane make it a taker for fast paced activities. It fits a bit large, and long (I wear women's S at 5.4 athletic built) and it feels a wee bit bulky. On the plus side I can actually fit a primaloft layer underneath for colder temperatures. Zippers run very well, small on first look but no problems so far; The hood is helmet compatible (also for the new bigger helmets), and the chin guard comes up nice and high, almost to the nose for those windy days. The hood is also easily adjustable with a drawcord on the back of the head. The wrist guards are super easy to adjust, and have nice sticky velcro that even works when wet. Two chest pockets are perfectly placed above the harness line for those of us who take this awesome piece into the alpine world - good size for bars and gus or a small cell phone.
The most impressive thing about the Firefox Active Shell - super light at 320g, and fits into a mesh bag smaller than a standard cup. Plus - the breathability is amazing! I walked up a glacier this summer in the evening, so it was a bit chilly, I wore a thin icebreaker and the Firefox Active Shell on top. After I while we had a break - I hadn't felt like I was sweating but the jacket was wet on the outside - This is a huge positive point for me, as I tend to get quite hot on the appraoches to climbs but then cool down very quickly when I stop - so it is great to have a jacket with a membrane that breathes so well and wicks moisture to the outside like this.
The lightness and breathability come to a bit of a cost though - super lightweight fabric means this jacket is not as robust as a Gore-Tex paclite or proshell - I would give it a slight minus on durability as the wrist cuffs are wearing out a bit after 7 months of hefty alpine abuse - but that is the prize we have to pay for super light gear I think. Overall, amazing jacket for any fast paced activity..and it makes you look like a pro (which is what we all go for, no?)

an ode to the firefox jacket
Reviewed By Ellie, 30 Apr 2012

stylish and well fitted is a bonus for sure, but what makes this coat is when i walk out the door, the gore tex means i'm staying dry, and this breathable fabric means i'm heading high, the top of a fell, or all round the lake, with this (bargain price!!) coat on an adventure i'll take!
