Disappointed, 21 June 2017
By Aileen (Edinburgh)
Bought this jacket in April 2016 to walk West Highland Way knowing I would need to keep dry in Scotland.
Going on mammuts good reputation and the price thought I was on a winner as it was goretex too.
Well Day 1 on our walk and brand new jacket soaked through to my undies !! Very uncomfortable on a 16 mile walk and also knowing I had another 7 days to walk.
But mammut have tested it and confirmed it's not waterproof and refunded me but that did not compensate me foe a wet West Highland Way!

By Thumper (Peak district)
Bought this jacket back in Spring last year, haven't worn it in the rain until today. (haven't worn it much at all to he honest as I don't hike much in the rain if I can help it!)
Unfortunately it has not performed well at all, it is completely wet on the inside, including the arms and even my hair was wet even tho I had hood up the whole way. Luckily I wore a puffa jacket underneath as I was cold and that kept me dry.
I'm really disappointed with this jacket, it looks great and fits well, but my baggy old Sprayway would have done a much better job at keeping me dry!

Great waterproof, 15 March 2016
By emashwell (Oxford)
This is a fantastic jacket, I'm realy pleased. I went out one early morning for a 20 miler and as the weather warmed up from -1 and foggy to sunny and 8 I didn't need to take it off. It's nice and lightweight, and the hood is comfortable. I'd definitely buy Mammut again.

Mammut ladies waterproof, 28 March 2015
By Janie (Gloucester)
The brighter colours caught my eye first, I bought the royal blue. The fit is just perfect, no fuss about the style, just simple clean lines. The hood looks good up. Havn't yet used it in the rain, but I'm looking forward to it! It's a quality waterproof, and one that will last many years I feel.
