Hi, i would like to know what skin you'd suggest for my skiis. i have a set of Betty by karhu skiis. my specks are166 long, 117 80 105. thanks

110. No doubt. you want wall to wall orange (with just the edges poking out) on that ski bottom, at least you will when you get almost to that ridge and hit boiler plate.

hi Cecile, There are two schools of thought for skin sizing. 1. (this is the classic and standard view) buy a set of skins that you will cut to the profile of your ski. this means that you need to buy a skin that's the same, or larger, width of the tip of your ski. in your case you'd need the 125mm. the benefit of this is that your whole ski is then covered by the skins, you'd have great purchase on all snow. the drawback is that it's a little heavier, you wont have as good of glide, and you'd spend more time and money. 2. it is becoming popular, especially with wider rockered skis, to get skins that are the width of your ski underfoot. this means that you don't need to trim the skin, except to shape the tip (http://www.blackdiamondequipment.com/en-us/blog/index/view/slug/tech-tip-taper-trimming-your-skins), and you'd save a few bucks. In your case you'd need the 80mm size. The benefit of this is that you'd have more glide and less weight. The drawback is that you might wish you had a little more purchase if you're skinning on sun/wind crust a lot. I'd recommend the 95 or 110mm skins. The difference is $10. You'd have to cut the skins (see video below) either way, but that's all part of being in the sport. I hope this helped. -Adriano
