These bottoms are very comfortable. They do run long. I am 6' 2" 165lbs and ordered mediums. They would still go down to my heels however the elastic at the cuffs keeps them in place. I like the feel of them under my jeans. I wore them in 30 degree weather and it was great. I traveled to the a... Read More

  • “I have a 35" waist, right in between medium and large (I run into this a lot and it's really annoying). Do these tend to run large or small?

    Asked by Jon2001 from Connecticut on 1/21/2017 8:31:58 PM
    • I usually wear a medium 32-33 range and these fit snugly right at that size(I ordered a medium). Material is super stretchy and they are designed to form-fit very close like compression or running pants. I would recommend going with a large.

    • I have a 35 inch waist and purchased the large which is fine in the waist and legs. Fits snug as it should. The inseam is long for my 5ft 10 height. Would rather have long than short.

    • Large is currently the smallest size that we have available.

  • “Size question. Looking for a gift for a 5'6 man in his mid 50's and works construction in MI. He is thin with about a 31 in waist and has thin legs. He wears 32 in waist jeans with a belt and they are quite baggy. Will the Small be best?”
    Asked by michiganrunner from Michigan on 12/17/2015 2:56:21 PM
    • First, if it's super cold you may want to look into a thicker layer. Second, small should work well.
      Answered on 12/17/2015 3:58:20 PM by D.K. from Kansas
    • You definitely want a small. I'm 5'6 with a 29" waist. I have muscular legs and these fit perfect. I would describe them as a "fitted" fit, slightly hugs your legs, but no where near a compression fit. Basically exactly what you want in a base layer.

    • Thanks for the feedback guys- Very helpful! Merry Christmas!
      Answered on 12/17/2015 7:03:16 PM by michiganrunner from MI
    • Yes, that should be the right size. They do tend to run an inch or two long, but since they fit snug one will barely notice.
