Sorry guys I wish I could call Sitka direct on this one but I’m heading out first thing monday morning and was hoping to get an answer by then. I have a pair of timberline pants I got in the mail friday. The waste seems like a good fit but the pant legs seem kind of tight. Is that just how they are? I’m not used to this high end system. Been doing carharts and sweats for years. Plan on putting core light and heavy layers on under these timberlines depending on the time of year. Just dont know if I should send these back for a different size or if Thats just this system. I see there are three fits also? Performance, standard, and expedition? How do I know what mine are? Sorry I tried researching this answer before this post. Kind of forced to order online as no one around here carries the pants. Thank you much!
