MONTANE VIPER HOODIE £80

A good mid layer is worth its weight (or in the case of the lightweight Viper, several times its weight) in gold – particularly at this time of year when it’s noticeably chillier, but not full-on freezing, and the odd warmer day still crops up from time to time. The versatile Viper features warm yet breathable Polartec Thermal Pro fabric for low bulk and unrestricted freedom of movement, making it perfect as a layering jacket to be worn under a shell, but also mone that can be used as an outer layer on warmer days or in more casual base camp environments. www.montane.co.uk
