Create your own microclimate for maximum comfort, whatever the conditions. Our layering system is packed with options for just the right combination of cozy and breathable.

Underwear - Start with soft and lightweight merino next to your skin. Merino fibers naturally absorb sweat and resist odor, so they’re essential if you want to feel fresh and comfortable all day, all year round.

Base layers - Wear these super-soft tops and bottoms over your icebreaker underwear as your insulating layer. Choose from a range of fabric weights – the heavier it is, the warmer you’ll feel. Fit also affects warmth. Wear your base layer snug to feel extra cozy.

First layers - Your most versatile layer: T-shirts, tanks and tops. Choose from lightweight with short sleeves for the hottest days to long sleeves in heavier weights for winter warmth – either on their own or over your base layer.

Mid layers - Think of these as your ‘on and off’ layers. Wind picking up? Shrug on that hoodie. Sun coming out? Peel off that sweater and pop it in your pack. This is the layer you grab for ‘just in case’ that can make all the difference to your comfort levels.

Outer layers - From hard-working on-mountain jackets to that handy vest you grab for a wintry training session, outer layers insulate from the outside in, trapping in the heat generated by your body, and base and first layers, as well as letting your body breath during bursts of high exertion.
