I have used these pants a fair amount now and I am extremely happy with them. I'm 6'5", 38 waist and 33 inside leg and went with the xxl and found the fit perfect, when hiking synch the waist and wear them high allowing full leg movement for kicker/back/side country missions. They breathe really well and thanks to the venting overheating can be avoided, if they do get sweaty they dry out pretty quick when you stop exercising. Only wear issue I have had is internal, I wear a leg brace and some of the soft lining has come away at the point where the hinges flex constantly, but I feel this is not a big deal for the performance. Like I said at the start I love these and would happily recommend them to anyone I board with.
