Product Customer Reviews
I Use this for the gym. I do prefer 100% wool or natural fabrics. It does have a high percentage though. Odour control is good. Moisture management also good I think but I haven’t used it in high temperatures yet. I got a small size me having a 37-38 inch chest and it fits like a slim fit t-shirt so the size is good fit for me.
Had my eye on one of these for a while but my size was never available. Popped in to get another item when I was surprised to see my size available. Snapped it up straight away and really pleased with the quality of the materials and fit of the top. Just have to wait for another to come into stock now.
This is the second top I've bought for my husband. He really rates these tops. Merino wool great product
Great product, comfortable. Warm when you need it to be and wicks well when you’re hot. Will be getting more.
Best wool in the world especially for the outdoor person
Great product
I don't understand the design concept of this T-shirt. There is synthetic material in the armpits to improve wicking, yet of course this then gathers bad odours, ie you lose the biggest benefit of merino just where you need it.
.
After reading reviews and description I thought it would be good for me when playing indoor sports but it isn't. It really hot and not very breathable. Could be good outdoors in summer months but let's see
I really didn’t know what to expect from this Considering it’s at least three times cheaper than other sports brands when it’s sunny you feel so much nicer than Cotton or polyester I also love the ventilated back and stretch panels the cut is great too & not riding up on my back. . Iv not yet tried it out in the field but city life’s been great I’ll definitely buy more & other items from shop
Great price for a merino wool base layer. Ideal for through hiking, very pleased.

Perfect, good material. Merino wool is a material.

Additional Product Information
Composition
Main fabric: 89.0% Wool, 11.0% Polyamide ; Yoke: 66.0% Wool, 24.0% Polyamide, 10.0% Elastane
How does the mt500 merino t-shirt limit odours?
The components used reduce bad odours. Laboratory tested to standard ISO 17299-3. Main fabric: 89% Merino woolMesh panels and a mesh fabric under the arms and in the middle of the back: 66% Merino wool, 24% Polyamide, 10% Elastane.
How does the mt500 merino wool t-shirt help perspiration evaporate?
When you make a physical effort and sweat heavily, the merino wool easily traps the insulating warm air and can absorb up to 35% of its weight in moisture without making you feel damp, which is appreciable in cool weather. In hot, dry weather, the evaporation of the water in the wool absorbs energy, which cools the body slightly at the same time.
What is the fit of the mt500 merino wool t-shirt?
This T-shirt has a slightly fitted sports cut to help wick away moisture to the outside of the fabric. Select your usual size, or one size larger if you prefer to wear your T-shirts looser.
Where does the merino wool used for the mt500 merino wool t-shirt come from?
We use wool from merino sheep bred on farms in South Africa that do not practise mulesing. We decided to build a partnership with a group of breeders (Konsortium-Merino) to guarantee traceability, meaning we can guarantee the origin of the wool.
A tip before using the mt500 trekking t-shirt?
For a softer feel, wash your t-shirt before first use.
How do i wash my mt500 merino wool trekking t-shirt?
We recommend you machine wash your Merino wool T-shirt at 86°F on a normal cycle with Merino wool liquid detergent sold under code 8817234. Dry flat and NEVER tumble dry unless you want it to shrink by one or two sizes! You can find an article on looking after merino wool clothing on the Forclaz website.
