A Buff is a must have piece of kit for any trek, lightweight and stretchy tube provides insulation, sun & wind protection and can be used in a variety of ways. The Thermonet Buff still feels like its made from Buff's proprietary super stretch fabric but there is the addition of Primaloft insulation in there which makes it 4 times warmer than normal.
Ideal for people looking for a really warm but lightweight multifunctional product that can be used to offer maximum protection from cold during outdoor activities like running, hiking, ski mountaineering, cross-country skiing, biking or motorcycling.
Buff's Thermonet Buff has a much higher thermal insulation than normal, 4 times more to be precise. This comes from the use of Primaloft yarn in the construction. With this additional warmth it's fair to say this isn't going to be best suited to warm weather. It is still stretchy, comfortable, and is fast drying so it can be warn in any weather through colder conditions.
As with all Buffs, the versatility is key. It can be worn like a scarf, as a beanie or headband and numerous other ways. What suits you will depend on how warm or cold you get when you're out doing things but no matter what you choose this Buff is easy to change on the move and is great for keeping you warm.
