THE BEST period.
Just purchased these as an encore to my previous AK Guides. They lasted 3 seasons of abuse which is incredibly long for my gloves. The AK Guide features my three necessities in gloves: Goretex, leather and insulation.
The Guides keep your hands bone-dry, and the poly material on the back of the hands allow your hands to breathe unlike all-leather gloves.
I strongly suggest applying the supplied Nikwax to all the leather. Though the Goretex membrane will block water from getting to your hands, if the leather is left untreated it will soak up water, get heavy, and suck warmth out of your hands.
Sizing is standard Burton. I had to get the XLs as I do in every Burton glove.
