Warm and good quality
I bought this set for a trip to Iceland and wore for 3 consecutive days in cold conditions. Kept me warm even when my trousers on top got wet. Runs slightly big but I prefer this for hiking and layering. I’m 5ft and the leggings run long, easy to roll up though. Quality is excellent and overall it’s good value for money and merino wool is the best for keeping you warm!

Excellent thermals
Excellent product went to Sweden ski holiday. -19 and felt warm all day. Highly recommend these to stay warm and cosy when it’s freezing cold.

Comfortable and not itchy, generous sizing.
So comfortable and warm. Very long for larger people and generous in size but then I am petite. The material is not at all itchy and not too thick for under clothes. I wear as a house outfit and put a long coat on for the school run, it looks perfectly acceptable. I believe I got an absolute steal in the Black Friday event!

Good
Got a size M, bottoms are perfect (I’m 5ft9 with 28 inch waist and 40 inch lower hip) but top could be tighter (34 inch bust) I’m usually a size 10 uk.

Love these!!
These are super warm and great quality! I think they may run a bit on the small size because I was told by the AI tool that I was a small but I wish I’d ordered a medium as the waistband is a bit tight. But I still love these!

Kept the recipient warm when her heating failed this winter.
These have been a godsend to my sister! Her heating system failed this winter and it has taken a while for it to be fixed. Although her house has been cold enough to see her breath in, these kept her toasty and warm without having to layer up her clothing until thick and bulky.

Item faulty
In less than 9 months and maybe only half a dozen times wearing this item has numerous holes and ladders (not moths!). I am about to approach Amazon for their view.

The set of Merino Women"s Thermal Underwear Top and Trousers was a perfect choice and it is just as described. It also came with a pair of Merino wool socks included. The color name is 250 Natural Merino which looks great, the quality is according to my expectations and the outfit is really warm and pleasant to the skin. I definitely recommend it.

Tevreden met mijn aankoop. De mix van merinowol en synthetisch materiaal zorgt ervoor dat het niet koud aanvoelt op de huid. Heel aangenaam om te dragen

its so great to find merino wool clothing / underwear - finally on Amazon. thank you. black set - top and leggings, although it was not clear if it is a set while ordering or if that is only the top unit. would be great to be more clear in text / description - for the ordering process. - the trousers/ leggings is a little transparent, so it is quit a thin quality and see-through. - marino wool quality is great, thin enough, soft touch, very nice. - black color is a nice dark black color, so great while new ! - fit is ok-ish for e.g. for XS ladies, and quality is nice, a little light on lower arms maybe or upper legs, but its doable, but - here comes the BUT : >> so while the fit is direct on the skin which is good and needed to keep warm, the material is actually itchy, sorry to say and yes very sad. hence I can only give 3 stars. Maybe the material combo would need merino wool mix with silk, I am not sure, but it is uncomfortable, even just while trying it on to check the fit/ size/ fitting. Maybe the itchiness can go over times with more washes ? again I would only hand wash and lay flat while drying, .. not sure if that will work to get rid of itchiness. - However I am grateful and happy one can find 100 % merino on amazon here in the ME region while coming from UK, GER or USA, because i like to avoid all synthetics, incl. polyester, nylon, etc as they are unhealthy for our body and smelly while sweating. - I think this set can even work well for sports, specially on travel, where you need leggings, so I would use those long underwear leggings for sport and as underwear. - I wonder if other color sets are less itchy .. ? - ps. I think the blue set, same material is less itchy while trying on, not sure how that goes, but it feels like it on the skin. ……

Schade, dass es diese Schönheit nur in einer Farbe und nur in einer Stärke gibt. Ich hätte liebend gerne auch einen Sett in 320 Gramm/ m2, am liebsten auch in Grautöne oder Tiel. Was nicht ist, kann noch werden, die Hoffnung stirbt zuletzt. Drückt mir die Daumen! Größe M passt leicht locker aber S ist dafür leicht zu klein. Beim Tragen weitet sie sich aus, aber man kann das mit einer kurzen Wäsche ud in Form ziehen wieder in Originalzustand bringen. Ich wasche sie lieber von Hand, auch wenn Maschinenwäsche erlaubt ist. Ich will das gute Set so lange wie möglich benutzen. Die Socken sind leider hit und miss. Die hübschen hellgrauen kommen unvorhersehbar, oder die Antrazit und kratzend. Geschenkt sind die nicht, man kauft sie mit, hat aber kein Mitspracherecht über Größe und Beschaffenheit. Frustrierend.,
