Thermolite vs Merino

Yeah, but the other point is that I don't want to have to worry about using "proper" detergent to wash my stuff, either at home or away. Quite frequently on trips, soap or shampoo in cold water is the mode of washing, and this categorically does not work with smelly-hellys, but does with merino!

BTW you do know that merino comes in multiple weights? I happily use it year round without getting sweaty and I generally run quite hot.

Yeah I know it comes in different weights, I only sold high end outdoor clothing for nearly 4 years, I never learnt nuffink in that time innit.

:p

Did you know that Gore-tex comes in different weights to?
and that they changed the construction of Gore Windstopper before general release because it wasn't breathable enough.
I've still got a pre-release sample bodywarmer from a Berghaus rep years ago made from the stuff, and its good but not up to the quality of the new stuff that they used when they put everything into production, my Gore windstopper gloves were a lot better in terms of breathability.

Anyways all this talk of Merino and Lifa....Outlast™ is where its at when it comes to temperature regulation if you get hot all the time, my Wigwam Outlast socks were nearly £30 a pair but worth every penny....well I didn't pay anywhere near that, but they were still worth every penny ;)
