NO MORE OVERHEATING
Breathability can be a bugger to gauge. But of the 30-odd hard shells we tested, the Pinnacle, from British newcomer Rab, let the moisture out better than the rest. Credit the jacket’s two-layer eVent fabric, which, like most waterproof-breathable
fabrics, uses a porous membrane that vents sweat and keeps moisture out. However, unlike those fabrics, this shell doesn’t require a polyurethane coating, which can clog those pores (and impede airflow). With the hood stuffed inside it, some testers found the collar a bit bulky. But our only real gripe is the weight: The liner and excessively wide storm flaps all add up. 1 lb; rab.uk.com
