Mammut GoWarm (2014)

Here we get a bit more athletic. This is a high-performance technical top and the tightest fit in the men’s group, although it adapted nicely to my body shape after three outings and careful washes. It’s a complex blend: a merino and polyester face fabric plus a polyester-only inner lining, which together offer great temperature regulation on hard climbs. There’s also an antimicrobial treatment in the mix to cancel out the smells associated with polyester. The back is longer than the front, which keeps draughts from running up your back while allowing complete freedom of leg movement. It feels dense and sturdy without ever feeling too heavy and, while it definitely looks athletic, it still feels like a top that is built for walking rather than trail-running. The high collar is great and there’s a chin-guard for the zip.
