    UltraCORE Men's Thermal Long Johns is rated 4.4 out of 5 by 42.
    Rated 4 out of 5 by from Good at that price. While I haven't had these long enough to really put them to the test, so far I can say they appear to be worth the heavily discounted price I paid for them. The navy print is a bit strange, I guess it's like a super subdued blue camo or something... actually it could be a world map... anyway the fit is good and they feel quite robust, and at the price I got them I would be happy to bash through some bush with them under my shorts. The fabric feels quite nice, much nicer than my old cheap polyprops, and I haven't had any static crackle off them yet. I would guess that the fit is fairly true to size, I ordered a small and they are snug, with a good length which may mean they run a bit small as I have very svelte legs. Like a dachshund.

    Rated 5 out of 5 by from Lightweight but cosy I bought these for my son to wear trekking in Nepal (he is still there - almost at base camp) he said they are fantastic, very comfortable to wear under his trousers and to sleep in (not sure if they have had a wash ha ha). He is especially pleased with the weight of them, and the wick away feature that keeps him dry and warm. Great product.

    Rated 5 out of 5 by from keeps out the cold bought 2 pairs on special to replenish husband's draw. Always a good buy on special. He finds these long johns are warm, comfy and quick drying and the elastic waist band does not loose it's "oomph" after one seasons wear as some of the other styles do.

    Rated 3 out of 5 by from Mostly great They are great material and fit EXCEPT one thing I am disappointed with the elastic around waist with my set. It is too loose/weak. Would have been full score except for that, which makes you hesitant to recommend.

    Rated 4 out of 5 by from It keeps my legs warm I bought this on June, 26th 2016 and I'm satisfied with the product. I used it as my lounge wear base and it keeps me warm especially during winter like this. I have washed it and it doesn't shrink, just make sure you follow the washing instruction and product will be fine.

    Rated 1 out of 5 by from Warm but... As far as warmth goes, these are great. Where they are let down, though, is that they don't stay up on your hips. They keep riding low at the back & I'm constantly having to pull them up. Defintitely WILL NOT be purchasing these again.
