If you don’t get the first part of your layering system right then it isn’t going to work efficiently, so it’s worth giving it some thought and making good choices. Icebreaker and Smartwool make a great range of crew neck and zip neck baselayers and midlayers in 100% Merino Wool, these come in various warmth ratings and are guaranteed not to itch or stink! We understand that some people prefer to wear a synthetic baselayer so our range of synthetic baselayers from other brands like The North Face, Arcteryx and Odlo is available all designed to be wicking and breathable and treated to prevent unwanted odours to give you multi-day comfort.
Wherever possible try to match your base layer to your activity. A running base layer such as the Ron Hill infinity will perform differently to a Mountain Equipment Committed Crew, for example; the former is for cardiovascular activity heat management, the latter is better suited to the stop-start motions in climbing.
