Base Layers
More than any other layer, a baselayer must be synonymous with comfort. This is the fabric that goes next to your skin - it needs to give warmth, absorb sweat, move when you do, stay in place when your outer layers shift, and most importantly, protect your skin from heat and flame in flash fire scenarios. Massif base layers do all that and more.
