Awesome !

I love this tank top. Discreet, it disappears to bring a touch of warmth, softness and comfort under my sweater/t-shirt. Both on hikes and in town. No odors in a multi-day test.

A classic that never leaves me

Merino usually stretches, so I recommend taking the smaller size. I use it as an undershirt in winter, in summer for multi-day hiking. It doesn't bite or rub, it doesn't get cold or wet. It doesn't smell like sweat even after a few days. Merino when wet itself smells a little like sheep, but only in a wet state, it may scare some, but its practical properties outweigh it.

Excellent, including during pregnancy

I'm very satisfied because: - it's nice on the skin, it doesn't scratch at all - the length covers the back well, it lies well and it doesn't keep rising on the back so that I have to keep rearranging it - after 2 winters of wearing it, the second of which in pregnancy (all pregnancy, autumn-winter-spring) looks like new; he didn't flinch; - although it stretched very well on the pregnant belly, it kept its original shape and did not stay stretched, nor did the fabric thin out; at the beginning of the 9th month it covers my pregnant belly (big, very big) all the way down, which is surprising considering that it is not designed for pregnant women; in addition, I don't even feel that it tightens me (and I'm sensitive to it, I can't stand anything tightening on my stomach) - very good thermal insulation, I also tested it in Iceland (end of June) - it actually absorbs moisture very well and it does not promote unpleasant odors, on the contrary For me it was the first merino tank top model tested, and I don't feel the need to explore others (as I usually do with any product) because it effectively meets all my needs. That's why I recommend giving it a try.

Love it ❤️

I used it as a first layer under the merino wool blouse from the same collection, it is extremely comfortable and nice on the skin. I will also use it in autumn because it absorbs sweat excellently.

I use them almost every day

I immediately bought a few and I use them all the time. Fantastic!

Best buy for traveling…

Best purchase for travel and everyday wear! The fabric is a little scratchy at first, but after a few washes, not at all. Does not retain odors, keeps you warmer than a classic tank top and wicks away perspiration more quickly. I still wear it under all my sweaters today and it's an essential for hiking, and even sports. The only downside is that the straps are not adjustable so it is slightly large at the front.

How to wash your merino wool t-shirt

We recommend that you machine wash your Merino wool T-shirt at 86°F on a normal cycle, preferably with liquid detergent. Dry flat. NEVER tumble dry unless you want to end up with a Merino T-shirt fit only for a doll!For more information:

Product testing

We've tested the material in a climate-controlled room in order to determine its performance level. The results highlighted the heat-regulation properties of wool. Indeed, after making a physical effort and sweating a lot, wool helps to maintain a consistent body temperature while synthetic fabrics cool down faster. The unpleasant cooling or freezing effect is therefore reduced by the Merino wool.
