    PolyPRO Unisex Long Johns is rated 4.4 out of 5 by 133.
    Rated 5 out of 5 by from Great price, very comfy, wash well I've bought the tops and long johns for a few years now and love them. So comfortable to wear under my walking gear. Wash well in the machine and dry quickly. I buy when they are on special so great value for money. Being female I was a bit dubious about how well unisex sizes would fit, but no problems (I'm usually a Kathmandu size 10 and the XS is perfect for me). I would recommend that you try them on though. This year I bought navy long johns online and they were a tight, uncomfortable fit. The black ones in the same order were more stretchy and fitted well like my striped ones from last year. Also tried navy ones on in a Sydney store and they were tight as well. The store happily exchanged for another colour.

    Rated 4 out of 5 by from Comfortable! Because they are a unisex design, the crotch can feel kind of odd at first so I'd recommend trying on in store to get your size right. I ended up buying a larger size than I usually do. They stretch out a little with wear, but overall hold their shape really well and shrink back to right size with a wash. These are great as pyjama pants or for layering under hike pants. I do find with lots of walking they sag and you need to hoik them up, so could be irritating on long walks layered under pants. Haven't tried that yet. The sagging doesn't bother me though and not an issue for sleeping in, but might bother someone else.

    Rated 3 out of 5 by from Good price on clearance I like these for warmth but a few points- they are very long, they had a scatchy tag around the waistband (which i cut off) and the crotch falls down so have to keep hauling them up- maybe will improve after wearing for a long time. (They feel like they could do with some more stretch in the fabric). I am size 10 so bought Small. Otherwise great value for money :)

    Rated 1 out of 5 by from Poor Quality I purchased two long sleeve shirts and pants a few weeks ago and when tried on in the store, the size I normally purchase (medium) were uncomfortably tight, so staff recommended a larger size. I purchased the large size which were still quite snug, but comfortable enough. After a few days of wearing them, they had become very loose and stretched, which I was not expecting. I ended up giving them to a friend of mine who wears larger sizes. I am incredibly disappointed with my purchase and feel I wasted my money and need to purchase new thermals - but certainly not Kathmandu ones.

    Rated 5 out of 5 by from Outstanding Value! I first purchased these long johns for my partner about 8 years ago, in a store at a Westfield Shopping Centre. He absolutely loved them. These days I go online to buy them and I only have to purchase them for him every couple of years, as they are brilliant quality and last through repeated wear and washing. Brilliantly priced when on special (almost 1/2 price), I always stock up. Highly recommended!

    Rated 4 out of 5 by from Comfortable but ?may not last long I bought this product for winter night wear. It does give you warmth you are after and its great!! The only downside of it is that it may stretch quite easily and may get baggy very quickly. otherwise I recommend it! very comfy!

    Rated 5 out of 5 by from Super comfy super light This is the third set I own. I use them as pyjamas in the winter and it's the warmest I have ever been. Particularly when camping. Great value for money.
