Icebreaker Men's Merino 260 Tech Thermal Leggings with Fly

Helly Hansen have developed Lifa technology that offers both warmth and breathability in their base layers. This comes in a half zip, long sleeved design and a selection of colours. The zip offers extra breathability. Lifa offers one of the best moisture management technologies available. Lifa technology is different to most other synthetic base layers on the market offering a 2 in 1 base layer with 100% merino wool and Lifa Stay Warm Technology.

The Icebreaker Men's Merino 175 Everyday Long Sleeve is a classic, all-purpose base layer made with soft and breathable 100% merino wool fabric. This top is just a versatile as it is comfortable.

The Tech top is Icebreakers heavyweight base layer designed for the colder months or expeditions. Great for the mountains in winter but also ideal as a mid layer through out the year. The Bodyfit gives it a fit that's closer and not so saggy, giving you more warmth when you're out and about. This heavyweight champion also has a dropped hem which gives you more coverage and move ability when it's tucked in for the cold. As standard for Icebreakers base layers it also has an off the shoulder seam making it perfect for carrying sacks.

The Active Originals X-Warm Bottom Pant is the warmest edition of the Active Originals range from Odlo and they're sure to keep you warm in the very coldest of conditions. Odlo's Effect fabric treatment creates a strong antibacterial property with the help of its silver ions and as a next-to-skin item, it fits closely with the contours of your body. Thanks to the ACTIVE X-WARM base layer Bottoms, you can take on tougher challenges whatever the weather this winter.

The Odlo Active Originals X-Warm Top Crew Neck L/S Women's is an extremely stretchy long sleeved base-layer, and is fantastic at wicking whilst keeping you warm in cold weather. It features integrated panels which helps with moisture transport in key areas of the body and a very soft 3D knit material makes for a comfortable yet precise fit, close to the body. Flat-locked stitching and seam ends better the comfort and take away that itching feeling, letting you get on with the task in hand.
