We have been a big fan of these Craft baselayers ever since we pulled one of the long sleeve versions on and were consistently amazed at how this feather-light, wispy top kept us perfectly cosy on the move through some extremely cold weather.
This is the short sleeve version, but it still sports the same ultralight and soft-feel ribbed fabric which at the same time feels supportive but retains a complete freedom of movement for all types of sport. The open weave lets air permeate freely, so when worn without a windproof layer through the warmer months we still find it very comfortable and sweat wicking.
Craft boast the Active Extreme was worn to 38 Sochi Olympic medals, and we aren't surprised. A terrific and versatile baselayer that punches well above its feather weight and price.
