I am 5’6”, 130#. (Height is mostly legs) Got a M. Fits perfect. Great length. Great fit. LOVE the wide waist band, yellow accents for ties and yellow pocket button loop. These stretch and give really well. I’ve done a lot of trails involving crawling/shimmying/climbing on rocks and they haven’t pulled or anything so far at least. Love the deep pockets. They are really warm too. Camped in 30 degree and light wind, kept my bottom half nice and toasty. Makes a great camp pant, comfy enough to sleep in.
