You won’t regret this purchase
I don’t usually write reviews, and have been mostly unimpressed with how it seems like Amazon is slowly transitioning to Alibaba i.e. many “companies” creating products of questionable quality HOWEVER This Merino base layer is P E R F E C T. Absolutely warm and comfortable. Great thickness and weight. Looks super good and smelled absolutely fresh using it three days in a row skiing. It’s expensive but worth it. Wish I could buy four more pairs. Really is an outstanding product. Hopefully it holds up over the years.

Best PJ/Fall/Winter Base Layer Set There Is!
I’ve bought multiple sets of these merino base layers at this point for myself as well as gifts and they are by far my favorite winter/PJ clothing articles I own. They are super comfortable for wool, which can often be itchy. They are tightly knit and have a good amount of stretch. The arm and leg cuffs have built in elastics that are super durable and great quality. They fit true to size and the material is a perfect thickness for balancing breathability and warmth. I highly suggest giving this set a try. I’ve had mine for multiple years at this point and they are still in great condition. TLDR: Buy these now. They are a bit pricey but their value is more than worth the price. And you also get free gifts!

Even a Sasquatch would like these
Bought this as gift for my skeptical Salt of the Earth Hubs who was not aware yet of the true superiority that is merino. His face dropped and I had to put his chin back into place when he asked How Much. I was utterly unfazed and ignored his protest. I easily got past his merino gear green inexperience and told him to ‘just try them because these will change your life’ with a grin. To put it short and sweet: He proceeded to basically only take them off to wash over the next five months. His only comment, actually Using His Words: he wanted another set. This, so he always had some clean and multiple weights so he could regulate better and choose depending on the weather forecast for the day he’d be out. I noticed his old synthetics were crumpled in the bottom of his gear bags when he’d come home. The merino were always within reach on top, and gasp, folded! High Praise from this man, folks. It should be stated he is THE case for the legitimacy of merino, and these extremely well priced merino sets: he is a heavy equipment operator that works outside on top of mountains in some of the most extreme winter environments on earth and loves it. For you, the reader’s purpose, let’s just agree to put aside the elephant-in-the-room Crazy Factor of that last sentence for now and stick to the underwear. All I can say in his defense is this world takes all types. That’s only important here to mention since he’s not a dude that sits around in it next to a cozy fire all winter sipping from a tea cup. (That’s my job, lol.) This set was put to a legit durability test and in incredibly harsh conditions and stood up. Once prompted for more detail, and translating out of his customary grunts, shrugs and sighs, he said [paraphrasing]: he stopped noticing whether or not his body was cold or hot since he was the perfect temperature all the time and stopped sweating whether in or out of a machine. He didn’t have to wear nearly as many layers in general. He didn’t have to strip ones off or put other ones on depending on where he was and what was happening nearly as much. He stayed warm even when outer gear got wet with frozen sleet driving and he had to move back and forth outside from truck to machine to truck. He wasn’t losing gear and other layers from job sites, trucks, machines or in the snow nearly as much either from stripping off and forgetting. The merino set remained odor free for an entire work cycle between washings so he reused them everyday. They stayed true to fit and didn’t stretch out of shape even wearing for long periods and for multiple days in a row. All day comfort second skin feel. No bunching in the armpits nor crotch. Ordered the 2XL, biggest they offer I think. He’s normally 3XL big and tall, so I wasn’t sure if these would fit but as a first or second layer snug is good. His back and shoulders can be a challenge to find proper fit for and I often tailor his clothes and gear, but these are perfect with long arms and a long torso design to accommodate various sizes and shapes. Spare to tuck in even! Fantastic!: This is important since he sometimes has to do mechanical repair on the fly. On top of a mountain on the machines, before this merino set, his lower back would sometimes come home chaffed and raw from cold exposure from these situations. A red burn from bending over with elements beating on him, not wanting to touch his clothes since his hands and outer gear coated with grease, tucking back is not a desirable option. The winds are basically trying to tear everything off so to have it stay in place and enough fabric to remain tucked in? chef kiss. Going into this next winter season depending on where he is going this year, we’ll get another set at a different weight. He said he wanted that versatility this time.

Choose the right weight for conditions.
I wore these at a Buffalo Bills game in December. COLD, RAINY day. I stayed warm and comfortable. Super soft and fit perfectly.

It’s warm and comfortable
It fits well and it helps to keep warm. It feels soft and the quality is better than expected. It doesn’t feel heavy and it seems to be quite durable. I’ll be getting one for myself since they are good to have around.

Incredibly soft and warm
This base layer is the best I've ever owned. I purchased the heavyweight set, since I already have several light and mid weight sets. We are currently in a super cold spell here in the Mid-Atlantic region of the US, so I tested them out today and spent most of the day outside. They kept me warm, comfortable and dry all day. I removed my outer layers and have been lounging around in just the base layer like a pair of pajamas...so comfy. The non-itchy Merino wool may be a bit pricey and a little delicate to wash and dry, but these are worth the money and the trouble.

You will love this base layer
Im extremely happy with this base layer set I bought a second set and one for my wife. The comfort, warmth, fit and fell are amazing. These are top quality and top performing base layers keeping body heat in with breathability

Very warm
Pants are plenty long, material feels thick, good quality, and not at all itchy. I'm 5'7 and 170lbs. Good rise in front but I do wish there was a little more material in the rear...I have no butt and feel like it could have a higher rise! Bought for winter trip to Iceland- I no doubts at all this is going to work great. Same slim profile as other base layers I've worn in Alaska and skiing in the Alps, but heavier.

I’m quite impressed with this! Very soft and I really like certain accents like the way that the cuffs on the pants and the sleeves taper down to retain some heat better but to fit well either way gloves/boots, to make sure it isn’t in your way, just draped very nicely. The fit is snug, but not tight or restricting at all, and the merino socks are very nice. I’d say overall this isn’t the softest merino wool I’ve ever felt, other luxury dress brand fabrics are softer, but not they aren’t trying to do what this is trying to do, I’m comparing fashion to this technical, earth focused, based layer. And I think it’s soft enough for continued use without any irritation. I cut all the tags off and have gone on two 1.5 hour winter hikes in Canada and have been super comfortable. So far no odour, been great, and I even am enjoying wearing then around the house. Great buy especially for the money!

If you never tried merino base layer, you may not know what you are missing! The theory is that when wool is worn directly on the skin with cotton as the second layer, then the moisture migrates into the cotton layer straight through the wool making you feel dry and warm. It is a kind of feeling dry while wet effect. Merino wool is thin and gentle, does not bite, and stays odour-free for long. It is much thinner than usual sweaters and can be worn under a regular size shirt or jeans. This garment is true to size, and is stretchable horizontally, so it is likely to fit well. Its overall quality is quite good. I wore it during the recent blizzard, and it felt nice. The top looks good on its own and can be worn as the only layer for exercise, but they sell merino T-shirts for this. The fabric is not strong enough for wearing a backpack directly over it. It is a gentle fabric, so try to not stain it with eggs, fat, etc., because it can't tolerate strong detergents. Wool also dislikes bleach, high alkalinity substances, hot water (causes shrinking) and rubbing (causes felting). I usually minimise use of detergents, because wool is made of protein covered with fat (lanoline), and you may not want to de-grease that fat. So, just dip it in lukewarm water (25C), possibly with a small amount of wool detergent, or shampoo, or nothing, swish it a bit by hand, and then lay out flat to dry on a large towel. In a couple of hours hang it out, but not on a heater. It dries fast, quicker than cotton. Wool does not contain carbohydrates, like cellulose in cotton, which feed smelly bacteria. Healthy human sweat is composed of water-soluble compounds with added anti-bacterial substances, so washing wool is easy. I am using a merino T-shirt for in-doors exercise as well, but it is a different story.

Ich nutze das Merino Tech 320 g Set jetzt seit etwa einem Monat täglich für meine Abendläufe. Da es aktuell oft bis zu -6 Grad sind, war der Kauf absolut notwendig. Man merkt sofort, dass es sich um ein schwereres Material handelt, das sich aber extrem weich auf der Haut anfühlt. Nach dem Einlaufen spüre ich die Kälte überhaupt nicht mehr, man kommt sogar eher leicht ins Schwitzen. Mir war besonders wichtig, dass es sich um 100 % Merinowolle handelt und kein Polyester beigemischt wurde. Das zahlt sich aus: Selbst nach dem Sport riecht das Set völlig neutral und nimmt keinen Schweißgeruch an. Ein netter Bonus war, dass dem Paket noch ein Paar kostenlose Merinosocken als Geschenk beilagen. Einziger Minuspunkt: Trotz des hohen Preises treten im Schrittbereich durch die Reibung beim Laufen ziemlich viele Fusseln auf. Das hatte ich in dem Preissegment eigentlich nicht erwartet. Ansonsten ist es aber ein sehr hochwertiges, wenn auch teures Produkt, das sich für echte Winterläufer definitiv lohnt.

Excellent quality and generous offer (comes with the leggings, top, and socks as a gift).

I ordered these socks as they are the style my husband prefers, but mainly because they are a blend containing 85% merino wool, so I was hopeful that they would be both warm and comfortable. When they arrived I was really pleased to see just how soft they are, although there was no label to say they were merino wool, I wasn't shocked as very few socks seem to have labels. I did have to look online for the recommended washing instructions for merino wool socks which suggest hand washing was the safest method, but I've risked them on a cool machine wash, and they survived without any problems. I'm reliably informed that they are the softest socks he's worn, and are really warm, as he mostly works outside that's a very big plus. Overall they are soft, comfortable, relatively easy to care for, at the current price of £5.99 they are also a bargain, and they fit my husbands size 9 feet very well, so I'm more than happy to recommend them.
