Layering up correctly is really important, so for those who are guilty of wearing cotton vests under thermals, this is the base layer for you. Cotton is one of the worst things you can wear for a cold day on the mountain because it can’t ‘wick’ sweat or water away from your skin like other thermal materials do. This means you get colder quicker and will struggle to get warm again. This vest is made from DRYRIDE Ultrawick fabric so it dries really fast and gets that moisture away from your skin. This also makes it great for pretty much any other sport or outdoor activity – complete value for money! To make it doubly effective try a thermal sports bra, too.
