INOV-8 STORMSHELL

£180, inov-8.com

It doesn’t come cheap, but this ultra-popular waterproof lives up to its high price point. A super-soft Pertex Shield fabric provides the lightweight comfort, while 20,000 HH and taped seams keep you dry and protected in the worst of the British weather. It’s easily packable, too, so you can whip it off and stow it away when the sun rears its head.
