In reply to TobyA:
I've used both versions, the alpha hyper lite lined in the form of Montane hydrogen and alpha direct in the form of marmot 60
I have to say I'm not sure how the hyper lite version is supposed to perform to optimum with an extra lining providing an extra barrier to vapour, feels like it needs another high performance wicking base underneath which seems to defeat the object and warm things up excessively
Of course all these things are very personal, I run slightly cool, and I also don't motor along quite as much as I used to which keeps my temperature down, then of course factoring in weather
I do think though that there is nothing wrong with admitting that alpha direct is an updated version of buffalo, a great compliment no...
Whilst I'm on the subject of anyone from marmot wants to pipe up and tell me if driclime has a future?
