FreeNord NordTrek Merino Tech men's thermal leggings - Black

The leggings are very warm and functional. They work well as an extra thermal layer during walks or for sleeping in a sleeping bag at lower temperatures. They fit the legs perfectly and are elastic enough that the L size fits different body shapes.

This is a very successful product, especially for this price. Although they are not thick (which is a plus to wear under trousers), they really keep you warm and provide a pleasant thermal comfort. The addition of nylon means you don't have to worry about quick damage when putting them on.

The leggings are a bit too long for me, but overall they fit; it's hard to say whether they significantly warm you up – in my opinion, the difference is small around zero degrees, but it's still better than nothing. Plus point for not being scratchy and being quite comfortable.

These thermal leggings retain heat very well and wick sweat away, which makes them an ideal choice for being active on cold days. Made of merino, they are breathable, do not pick up odours and fit the body well. It's an excellent option for outdoor adventures – they boost comfort and efficiency in low temperatures. I'm ordering another pair because they really work well for hiking.

Very good thermoactive leggings – they don't scratch the skin, they keep the body warm very well and handle moisture effectively. I also bought a sweatshirt to complete the set and together they really make a great outfit for winter.

At first, they may seem plastic, slightly rough and thin, but that's misleading. The leggings are very stretchy, sit well on the skin, and quickly start to warm you up. Nevertheless, their mesh structure means your legs shouldn't sweat. They work perfectly as a layer under trousers. I gave them to my girlfriend and they fitted her feminine figure very well. PS: It's worth ordering a size bigger than usual.

Quite all right, but they're not that warm – you can feel the cold wind. Overall, they're nothing special. As for the merino wool content, it's more of a marketing trick – there's too little of it to have a real effect. Read other people's reviews.

These are outstanding tights, very comfortable, almost like a second skin. There's no risk of overheating even if it's not very cold outside. They perform excellently in frosts, and at higher temperatures they do not cause discomfort. I definitely recommend them.

This is the best thermal underwear I've had so far. Merino wool really makes a difference – it doesn't irritate the skin and doesn't absorb odours like synthetic materials. I use it daily both for work and as pyjamas. Combined with a sleeping bag of the right comfort standard, the comfort is so great that it can even get too warm.

Warm and comfortable, I really haven't noticed any flaws.

I always had a problem with excessive sweating during intense walks. Now, thanks to them, I feel completely comfortable.

Leggings combined with a shirt make an excellent set for frosty days. I have worn them several times already and they do their job well, although I feel a bit strange because of their tightness. The sizing is described very well – I am 176 cm tall and have a waist of about 88 cm, size L fits perfectly.

Great thermal long johns. They provide very good thermal comfort. I haven't tried them in severe frost yet, but they handle light minus temperatures well. I use them daily on cold days, and I often ride a bike too (under regular trousers). Everything works as it should. You can wear them indoors without needing to take them off. Size XXL fits for a height of 185 cm and standard build.
