Product Customer Reviews

I'm super happy to finally find a fleece kit that is light weight and fits perfectly. Will be a charm for fall/winter. Super comfy!
The fit of the pants is great - true to size although those that prefer a high waist pant likely will not like these. The waist hits 2-3 inches below the belly button so not at the most flattering point on most women. I like everything about these pants aside from the waist band/draw string particularly good quality of pant for the money. The elastic waist band is tight enough to not need a draw string at all so why did they put this weirdly thick drawstring in? I thought okay maybe if people want to size up 2-3 sizes for a very oversized fit they might need it. It isn't needed and causes lumping and discomfort in the wait band. I tried to pull it out but it appears to be sewn in in the back. Given the cost of the pants I decided to live with it but I've just seen in a side-by-side comparison in a targeted ad that the men's pant have a "normal" elastic waistband with no draw string. What gives? Why do men get the practical/comfortable waist band. Boo!
I bought these to go under waterproof trousers. Read the other reviews and decided to size up. Glad it did as they come up really small. I’m a UK 8 5’2” 50kg and had to order a medium! There’s hardly any stretch to them. The rise is super short so no tucking any tops in. No pockets. There were so many unnecessary large scratchy labels inside the waistband which I cut out. Positives … the fleece material is warm and the leg length ok so I’m keeping them.
I am a true size (UK) 12, 5ft 3 tall and bought in a medium and they are perfect in every way. Quite form fitting but don't dig in anywhere and aren't tight on my legs despite me not having thin legs. I wear them over compression leggings for hiking in winter. Have had some freezing cold days and the heat held inside these trousers is incredible. Even when worn all day climbing up and down a mountain, scrambling, sliding, bending, they stay put. My only criticism is they have no pockets. But I love them far too much to take a star off for that.
I use these as a part of my sleep system when hiking. I take a tiny naturehike summer sleeping back, combined with a +8 degree bag liner, puffy, fleece trousers and a fleece jumper, that system let's me sleep warm down to about -2 degrees C.

Super soft and ultra confortable to wear, it will be ideal to keep warm in the tent when I’ll go camping
I purchased a size small in these pants to use while climbing Mt Kenya, both as a base layer around camp and as pyjamas in my sleeping bag. They are well suited to both these tasks because they are form fitting and fleece is always going to be warm. HOWEVER, they are a little short on me (admittedly i have a longer leg inseam - 33inches) and worst of all, they have a really short crotch length! They are flattering as long as i'm walking around but as soon as i sit down or bend over the back rides down and it's a full moon! I don't think i have a particularly big bum and i have seen a few people comment the same so i think this is just a poorly designed product. I am hoping they have a size M in stock soon so i can try those on instead and see if they fit better. I actually tried on the men's small hoping they might fit better and although they don't ride down at the back, they feel much shorter in length and the fit was so loose that they felt draughty.
Warm, comfortable, light
Fleece outside which I didn’t expect. Very comfortable & neat fit.
Nice for lounging around. Have to send it to alteration as it was too long for me (I'm 5 ft).
Good product
very nice and comfortable trousers, soft and warm, they run small, I'm usually a size 12/14 and a XL is perfect.
Great value for price size are small so if you like a baggy fleece trouser get a larger size than normal Fantastic under a drysuit for sea kayaking or under salapettes for canoeing comfortable and quick drying for warmth, ideal for camping. A great cheap comfy basic fleece pant.
Very happy with it
Trousers are a nice soft material and just what I was after except the sizing is very small. I am a size 8-10 and bought size medium based on other reviews saying that they come up small but I wish I had bought a large because the medium is a very tight fit! I would recommend these trousers for the price but make sure to buy a couple of sizes up
