Verified Buyer Reviewed by kairmid from Boston, Ma on Sunday, October 30, 2011
Nice snug fit, super soft inside. And not just for men - I'm female, 5'10", generally wear a size 16 and the large fits perfectly. They don't sag, like my last pair (Lowe Alpine). Great on their own with a long tunic top, great as a base layer. And they're made in the USA, I'm trying to buy as mu... Read More

    Decent long underwear, very warm. Not that flexible, don't expect to run or do any squatting in these. Construction of the product seems good.
  • Reviewed by Jared from NY on Monday, March 23, 2015
    I am 5' 11.5" and 160-165 lb with a 31-32 waist. I got a medium and it was almost impossible to wear; very tight. I returned it for a large and that was pretty much perfect. I wear a Med in essentially everything when it comes to outdoor clothes, so I would consider this a definite size up. It is form fitting in the Large even, but that is how I think this piece is supposed to be.

    The material is better than I expected for the cost, smooth outside and fuzzy fleece inside. Other reviews are all over the place, and this L seems thicker and warmer than the M I returned, so I wonder if there are different production origins in here. I like the L enough that I may order another, see if the build is consistent on those.

    Ugh. The fabric is thin, the sizing ran waaaaay small and there was very little stretch in the fabric. I have other powerstretch clothing and it is nothing like this. Either Polartec has gone downhill or this fabric was taken from the company dumpsters. I ordered the blue - not sure if color makes a difference since there are good reviews on this product.

    I have worn these as a base layer in sub 0 weather and stayed nice and warm. They are very comfortable and don't itch at all. I read reviews that said these ran a little small so I got the large (I have a 32 waist, 32 inseam), but in retrospect a medium probably would have been a better size for me.

    These are warm and don't weigh much. My only complaint might be that they ride a little low and might be sized a little small.

    Asked on 9/23/2014 6:56:01 AM by Linda from Pa
    • Answer Yes, these base layers are different than any I've ever seen! When I got them out of the box, I thought these are not what I was looking for & my husband said the same thing. They looked like sweat pants, very thick & looked baggy not tight fitting. I said, "well try them on any way!" He couldn't believe how wonderful they were. They are tight fitting, so warm & so comfortable! He looks forward to wearing them when the cold gets here! I highly recommend these to keep you warm & very comfortable.

  • Question “Does the fabric pill on these? Thanks!!”
    Asked on 12/29/2013 9:55:07 AM by KFingC from RVParkUSA
    • Answer Has not to date on the 3 pairs that we use! Brendan reports that these are the best long underwear ever.
      Answered on 12/29/2013 11:08:24 AM by Molly from Avon, CO
    • Answer I have not taken them out of the package, because they appear to be so thick that I'm sure they will be too warm. I had a different impression of how thick they were from the photos. But the price was so appealing that I can't even justify sending them back. Maybe I will pass them on to a family member who skis. Generally speaking, based upon past experience with clothes, cotton/poly blends are the worst at "pilling" as you call it. 100% polyester does not pill at all. These are nylon/poly, which I predict will not pill at all. They do not have a fly, so they are unisex garments. Other similar base-layers have flys.

  • Question “Would these work for a guy with a 34 inseam?”
    Asked on 12/12/2013 8:07:43 PM by Rick from NY
    • Answer being a woman, I really cannot say, but these are very thick - which might be good if you are in snow country.
      Answered on 12/12/2013 8:59:34 PM by landscape painter from California
    • Answer I just tried these on and I wear a 32 inseam. There was some bunching of material around the ankles, so they will work for someone with a 34 inseam. I'm very impressed with them as they keep my legs very warm.
