Great set, warm, dry and comfy.
I have two of those in 250 and 320 grade and different shades of blue, so extremely happy to please my OCDs :D Really good fit - both in M fit me well with some room to spare, and I'm usually between S and M in common brands. Had them on on several hikes of various strain and length, and can't fault so far. Keeps me warm, dry and absorbs next to none of body or antiperspirant odour. Perfect buy for layering and honestly the top looks good on it's own if you really need to shed layers. So far they seem to be surviving washing without issues (wool liquids, wool mode, two spin cycles, dry flat on a towel on a rack) so fingers crossed for durability that it holds for a long while. In case you wonder, yes there is actually a weight difference between the grades :D If I recall right there was around 400g difference from 250 to 320 set when I weighted it. I might get one more set just in case for spares if it comes on a good discount :)

Great base layer
Quality merino base layer at a fair price. Used multiple times for hiking, skiing and water sports (kayaking, canyoning, rafting). Warm, breathable, quick drying and fits well. Couldn’t ask for more!

Bought 2 of these. Followed the sizing guide. They don’t seem true to size. . When put on you could feel the cold. As if the material was been overstretched and opening the fabric up to let the cold draughty air in. So Returned these. And went up a size. Then Bought large, the next size up and now they are super comfy and warm, really love them. And they look good, and hug the body nicely looking to buy another one if they come down in the January sales

Feeling dry in wet - a high quality base layer
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.

Sizing is right on.
A heavy duty merino wool base layer set. Bought for a trip inside the arctic circle in January. Arrived on time. Sizing is right on. Can’t comment on durability yet. The free socks were a bonus, but delicate and already have a small hole. So far, I would buy again from the seller.

These are great!!
I'm really impressed with the feel and quality of workmanship of this set. I have no reason to doubt that they are 100% Merino wool. They certainly feel like they are. The seams and stitching are excellent. I am always in-between sizes. I would say the sizing is easy fit not tight. so a large on me fits, but it is a bit looser than other sets I own. Go a size down if you prefer a "snugger" fit. 320g /M2 is what I purchased. They are warm to wear. But I wouldn't say exceptionally so. However, I am happy with them and they are likely to become my go-to set for really cold conditions. I would but more of any weight from this manufacturer.

Good quality stuff 👌
Very good quality garments. Bought these for my husband for the colder months motorcycle rides and he is very happy with them. Washes well and seems to be holding up nicely.

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.

Già a prima vista, appare un prodotto molto curato. La lana è molto pettinata liscia e quasi setosa, a me non dà nessun fastidio sulla pelle. La taglia è perfettamente adeguata anche se io preferito prendere una taglia in meno rispetto a quella consigliata perché voglio utilizzarlo per lo sci e quindi preferisco avere il capo bello aderente le maniche della parte superiore sono effettivamente più lunghe rispetto alla Norma e questo secondo me è un’ulteriore plus. Dovendolo riacquistare probabilmente sceglierei la grammatura massima, perché immaginavo che quella intermedia sarebbe stata più pesante. Comunque è già sufficiente.
