G3 improved upon its legendary climbing skin design by using plush, high-traction synthetic material on the base of the Highfriction Splitboard Skin. Compared to previous skins, the high-friction material offers a 10- to 20-percent increase in traction on steep, hard-packed surface. Couple this increase in climbing ability with tip connectors that give this skin a glove-like fit, and you get the ideal solution for ditching the lift crowds in favor of untouched lines.
I have a medium for my 161 carbon but I can also use these on my 156 hovey. I would recommend following the manufacturers size ranges but this does work for me. These skins have been in the quiver going on their second season. The glue held up really well through heavy use last winter then in south america this summer I noticed some glue sticking to the base. It's time for some new glue on this set. I didn't take very good care of these in these. In the summer months preceding SA they were rolled up in a very hot truck as I road tripped across the country. I think this had a lot to do with the glue going bad after 1 1/2 seasons. Im still really impressed by these for their climbing potential. You can go strait up pretty much whatever you want, which is not always a good thing as I found out in Chile but thats another story. The major difference aside from the climbing potential between this skin and the alpinist is the glide. This skin offers almost no glide on flats and you need a decent slope to get them going and ski down. This is a trade off though, if you tour with billly goats get these skins, if you want to conserve energy on the flats or have long approaches to get to your zones these are not the skin for you.
