Windproof, waterproof and stealth proof, 28 March 2016
By The Walking Dad (Huddersfield)
I'd been saving up to buy a proper wind/water proof jacket as a few walks in 'named' storms left me soaked to the skin. I couldn't decide between Gore Tex Pro or Neoshell until I saw the Whymper jacket on offer, which made the decision for me.
The jacket does everything it say it does. I thought I knew what waterproof was (and thought windproof was just 'marketing-talk'!) until I took the Whymper jacket out for a spin.
In awful conditions you'll feel cocooned inside it, hearing the wind and rain but not really 'feeling' them.
If you go for the red version then chances are you'll never get lost too. 'It has no stealth mode' according to my son. You can probably be seen in it from the moon to be fair.
5 stars so far for this item.
