womens brown fleece jacket:Synthetic Thermals

Most synthetic base layers are made from a polyester or a polyester blend. This material is known for its durability, comfort, versatility and most importantly its moisture management. Because of this, synthetic base layers such as our Geothermals (mens and womens) and Prothermals (mens and womens) are more suitable than merino when it comes to high intensity activity.

It’s a little known fact that technical exercise wear worn as a tee in summer sports is the best high intensity winter base layer, and we have a specific range of base layers created specifically for ultimate performance on fast-paced adventures. Our collection of Warp garments are incredibly lightweight and sit comfortably on your skin. This range is made from Polartec® Power Dry® which is engineered to move moisture off your skin, and to the outer surface of the fabric. Power Dry® is also incredibly breathable, fast-drying and easy to care for.

When to wear it: Polyester base layers are great for medium-to-high intensity activity. Our Prothermals, for example, have been engineered with a grid construction so that they simultaneously trap warm air and move moisture away from the skin – these are great for winter trail running, mountaineering, and ski touring. For winter trail running and similar high intensity activities, Warps are an excellent choice due to their advanced moisture wicking performance. Our Geothermals on the other hand, are excellent all-rounders. They’re ideal for winter hikes as they don’t absorb moisture, so will not get heavy while you’re exercising.
