MONTANE Slipsteam, £50,

This featherweight 78g gilet is aimed at bikers and other fast-moving adventurers. The ripstop Pertex fabric is supremely breathable, wind resistant and keeps light showers at bay; a more robust Pertex is used on the shoulders and lumbar area, while a mesh back panel ensures you never get clammy. It packs down into any pocket, which is probably why we’ve used it more than any other item this year. Sizes S-XL. JK

PROS weight, keeps core warm
CONS none
