When the temperature goes sub-zero you'll certainly be glad of these. The Rab men's Merino+ 120 Pants offer a superb balance between warmth, breathability and moisture control, and they work amazingly under soft shell or shell trousers.
These base layer pants combine the best properties of Merino wool and of synthetic fibres, to create a wicking, breathable, temperature regulating and odour beating winter gem. They're ideal for use year round, although they come into their own above the snowline, for mountaineering, ski touring, hill walking or for cold weather cycling. Due to their inherent odour resistance, these long johns are great for extended multi day adventure, where access to laundry facilities may be many days apart.
Rab's unique Merino +™ fabric (Replaces MeCo products in the Rab range), is created using a combination of superfine Merino wool and polyester with 37.5™ Technology.
Merino wool is a wonder fabric, being very soft against the skin and is superb at regulating temperature. This means it's comfortable in the heat and in the cold. It is 100% natural and sustainable, unlike the petroleum based synthetic fibres used in other base layer garments. It is also quick drying and naturally odour resistant, making it the perfect choice for extended backpacking trips, where laundry facitlities may be few and far between.
With Rab's Merino+, the addition of Polyester fibres hugely improves thedurability of the wool and helps keep the garments shape. Combined with 37.5™ Technology, you have an amazing baselayer fabric with Merino+, that not only regulates temperature and resists odour, but also moves moisture more effectively and has more longevity than a pure wool.
