Most comfortable all purpose cool season tights

Awesome, amazing, comfortable, warm base layer, lounging around the house, all purpose cool temps tights, without the squeeze but yet some what form fitting

Warm and tight

It really does what it say: keep you warm and it is tight. I am used to wear underwear + this one + one Jean or a rain trousers and I am hot. It does keep you warm perfectly. Can be used also as pyjama or relaxing pants on Sunday movie on the sofa. Only things: do NOT put it on the dry tumbler (as it is mentioned on the notice) as it will shrink a lot More colors should be available.

For the price, these are well worth buying. They kept me warm in the house when my central heating failed for few weeks.

Fleece sleepwear.

I bought these and the fleece long sleeved top to sleep in at camp, I tried them out last week combined with thermal socks and hat and they were absolutely brilliant, I was toasty warm inside my sleeping bag and you can even wear them during the morning to make breakfast as they're quite acceptable as day wear. Whatever your desire these warm and comfortable fleece bottoms will fulfil many roles and are excellent value for money.

Perfect Lightweight Warmth - Ideal for Backpacking

Only 160g on my scale! Super warm and snuggly. Great for sleeping in, or alternatively wear underneath your trousers to add a lot more warmth to them. They roll up fairly small but the most incredible thing is the weight - not just a pair of trousers, but WARM trousers, for 160g... and only £8. If you ever hike in cold conditions, buy these fleece trousers, you have absolutely nothing to lose. I absolutely cannot recommend enough. I got a size up and they actually feel like trousers, rather than tights/base layer/leggings, which I like. Overall an invaluable piece of kit, especially for anyone trying to keep their pack weight down. For this price there's simply no reason not to.
