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.

Great for cold weather running
These keep me warm while running down to about 25°F. I live in a warm climate, so I can't handle the cold as well as others, but occasionally I have to run when it's cold out. These are super thin and light weight, they're really comfortable and soft, and they fit perfectly.

Best base layer I’ve ever purchased.
Top notch base layer. Bought this for my wife and I and it’s very warm & very comfortable. It didn’t shrink at all when washing and drying. I’ve used many base layers over the last 30 years and this is by far the best. We both got the 250.

Warmth, comfort, and WOOL
This was a gift for my partner/best pal ever. He loves them. I also have my own and they work wonderfully as a layer in the cold weather. They are smooth and flat so that they can layer underneath almost anything. They provide warmth as well as block air that can pass through regular apparel. I would buy them again for myself and as a gift. The gift set with the beanie and socks was such a neat bundle as well!

Expensive but well worth it
I've had this for about 2 years of worn it in the deepest cold of winter, the quality is extremely high it's correct what they say you can wear it outside as is in about 20° weather and stay warm I needed something for my motorcycle how I wash it is on a general wash and I hang dry technically you're not supposed to hang it cuz it will stretch the wool but I do and it's fine after one day of drying yes it's expensive but it's well worth it!

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!

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.
