The Mammut MTR 201 Micro Jacket is a very lightweight windproof top.
First off, I was really impressed by its weight – or lack of it – the small clocking up only 81 grams on the scales!
The jacket features a full length zip with a small chest pocket, (a feature I really like for stowing compass, cut down map, gloves etc.) The pocket has an internal hole for headphones (so that you can take your “multi media device” with you to the hills and listen to man made sounds rather than birdsong, the wind in the trees, the tinkling stream etc!) There are elastane mesh panels below each armpit to assist breathe-ability (I think these will be good whilst running but a compromise to the jacket’s wind proofing and thus not so good if using the jacket whilst standing around), a hem draw cord and something called finger gaiters in the cuffs (basically an extra bit of material that might, at a pinch, keep your fingers warm although I can’t see how these would do the job of a pair of gloves!) It is DWR treated to make it shower as well as wind proof and time will tell how long lasting and effective this proves to be. Reflective lettering and logo give a little bit of increased visibility at night. The jacket easily fits into its own chest pocket for storage.
I tested it out whilst trail running on a breezy but sunny October day. In action the jacket was very comfortable and whilst the close fit of the small wouldn’t allow it to be worn over bulky layers, as a running wind proof over a long sleeved base layer the fit was excellent.
Mine is a fetching bright green which matches the MTR 141 trail shoe although it should also be available in black.
Overall I was very impressed with the jacket, it fits well (I usually find small men’s size to be a bit big!) and is ideal for wearing on a chilly day when you know it isn’t going to rain. It looks good too – if you like green!
