Live the long sleeve length and the weight of the shirt. Haven't worn in summer yet, but I think it will be good for hot weather as it is loose fit. Super comfortable and you don't need to wash very frequently.
I have to say i love my pinnacle, I wear it while riding as its warm and light but doesn't over heat like synthetics might. What i didn't realise is how amazing it is in the rain - I got caught riding in a real down pour, normally this means i'm cold and heavy as well but not now. I was wet, sure. but the wool kept me warm and I was able to finish without discomfort. Awesome - Thanks IO
