I also wore the back out of my Icebreaker one after ooh.. five or so winters, where my camelbak sits. Ok so it was a fair bit of riding, but none of the rest of my kit has ever gone through like that.
The £6 reduced base layers from Mountain Warehouse are astonishingly WAY better than the £60 Icebreaker. I was quite surprised acutually – I put one on for the first time and felt instantly cooler as it wicked so well.
so I’d say that if you use a camelbac or similar “wicking” pretty much goes out the window
Well no, the camelbak only covers a small oblong on your back – the rest of you can still be dry. With merino, you’re soggy all over. Warm though, granted – and I did use merino more in cold weather.
