  • Very comfy, but awkward
Size: Large Color: Open Fly-a-black
I like the feel of these long johns, just one thing is the bottom half is awkwardly mis-shaped, so much as I have to pull them up quite high on my body for them to fit properly on my buttocks and private parts, where the waistband is at my chest level. It isn’t to much of an inconvenience, just kinda strange, but I believe the company can save a bit of fabric if they reinvented the lower half of the outfit. Thank you :) ... show more

  • Great fit and warmth.
Size: 3X-Large Color: Turtle Neck-b-army Green
I work in a refrigerated warehouse, and hate the big bulky coveralls and jackets that are provided. I like to be high speed and low drag, and be able to move freely. This base layer is fantastic. Fit is awesome, fabric is super soft and stretches with you. I am 6' 225lbs with a body building style physique. I bought the XXL based on the size chart for my dimentions. With this base layer, and my lightly insulated softshell jacket, I am plenty warm in a 34° warehouse. Very good product. I will most likely buy more for ski season. ... show more

  • (((This might help you)))
Size: Medium Color: Green
I know there is a lot of questions and complaints about sizing, but I think people tend to forget that these aren’t suppose to fit like a regular shirt and pants. These are meant to be stretched over your skin and fit very snug. For instance, if you normally wear a size large top and bottoms, you should be able to order a large in this outfit and it fit ok. On the same token, with the amount of stretch to these, the medium should also fit, just fitting a bit more tight than the large. I believe these are measured and sewn a bit smaller to allow them to fit your skin more snug. Also, the main worry should be the length of legs and arms on this outfit. Now I am 5’10 but only weigh around 130. Now, I could order a small for it to fit me snug, but then the length of the sleeves and the legs would also be shorter, so I can’t. I have to order a medium to fit my longer limbs. Annoying? Yes. But that’s how most clothes are made. They go by average specs. If the size itself drops, everything on the design drops also. All this being said, if you wear a size medium, buy a medium. If you are a large, buy a large. Just buy the size you wear and these will in fact stretch to fit you. Now if you are built slightly abnormal like tall and skinny, just account for the length of your limbs and know that you will need to buy the size that will accommodate your leg and arm length. This also means that this outfit might have to be a bit more loose on you. Now if you are a large person, but are short, you should still order your size. Yes, you might have some extra length in the arms and the legs of the outfit, but that’s not a bad thing. It’s better than them being too short for your build. (....as for how good these are, I bought these top and bottoms about a year and a half ago, and these are still holding up great. I wear these often as I’m a person that always feels cold. So having outfits like this to layer under other clothes helps me out a lot. These also make great outfits to just kick it around the house in. I wash mine normally with other clothes and have had no issues. My only suggestion would be to try to avoid drying them in a high heat scenario. With the material being what it is, it’s best to just dry them on a warm temp so you don’t damage the effectiveness of its stretch. Like I said earlier, after a year and a half, mine is still going strong. I recently decided to order a couple more sets and figured it might be a good idea to leave a review as to how well mine has held up. I seen a lot of questions and comments on the sizing and figured I would leave my thoughts on it hoping it helps some of you out trying to figure out if this is the set you want and what size you should get. ... show more

  • Just as described
Size: Large Color: F-camo-black
We live in Florida so my son didn’t wear them yet. He will be wearing them in Pennsylvania for hunting, they are tight but should keep him warm. My son is 5’10” and weighs 150, ordered him a Large, he is happy how they fit.

  • High quality
Size: X-Large Color: Black
Very warm. Really happy with these. They do fit tight so don't be afraid to order one size bigger. But they are made to fit tight they keep you super warm.
