Hey Mike! Nice skis! Yup, unfortunately 120mm is the widest I have in these skins. I have a wider skin here but 125mm is the widest that we have from them. Off the roll, these skins are as long as you want (until we run out)! Not sure exactly what you mean by "stiff for climbing" but the glide is pretty impressive and the grip is even more impressive! Let me know if you have any further questions!
