Great product, 24 March 2017

Well made and comfortable jacket. The inner jacket is a dark blue colour is well constructed and warm. Good quality materials used to make it.

Good until the waterproofing failed, 05 October 2016
By Adam D (York)
I enjoyed 6 months of good use out of this jacket, in varying conditions from day-to-day use to hiking excursions. I particularly liked the inner as it functioned as a useful spring/autumn insulating jacket for dry days.

However, the waterproofing did not stand up to the Norwegian rain! After two hours of solid rain, on what was planned to be a full day excursion, the waterproofing on the outer failed and I became wet through.

I sent this jacket off for repair for a minor tear in the sleeve, and Mammut returned it to my local Go Outdoors without having repaired the small tear in the seam of the inner. I did receive a full refund, but was disappointed in the quality of the waterproofing on the jacket, and the service received from Mammut.

Great Jacket, 15 September 2016
By StripeyGinger (North Yorkshire)
As you would expect from Mammut the jacket is extremely well made with cords in all the right places to provide a tight fit in wet weather. The inner jacket is extremely warm and almost certainly too warm for summer months. With the inner removed it is a great summer raincoat
The jacket is extremely water proof and likely to provide sufficient warm for all but the worst winter weather with the inner jacket.

Watch the sizing though as Mammut jackets come up smaller than other brands so check a size chart before you buy
