Womens Merino 150 Active Blend Short Sleeve Crew (Navy)
This short sleeved tee is designed for higher-intensity days when breathability and movement matter most. A lightweight merino blend paired with a mesh eyelet knit construction delivers exceptional airflow, helping you stay comfortable as the pace increases.
Ultrafine merino wool naturally wicks moisture and resists odour, while added stretch allows the fabric to move with your body. Flatlock stitching reduces friction over longer distances, making it a strong choice for active hiking and fast walking.
Side splits at the hem improve mobility, and a reflective Isobaa logo at the rear adds subtle visibility in low-light conditions. Every detail is considered, without adding unnecessary bulk.
This is performance-driven merino, built to work hard while still feeling soft and comfortable against the skin.

Fabric weight (gsm)
GSM means grams per square metre. Higher GSM usually means a thicker knit, more warmth, and better wind resistance.
Lower GSM usually feels lighter, dries faster, and is better for high output.
Fibre diameter: 17.5µm
Fibre diameter (microns)
Microns measure the thickness of each merino fibre.
Smaller microns usually feel softer against skin because the fibres bend more easily. Larger microns usually feel firmer and can be more rugged for outer layers.

Great cut, really light & super breathable. But the fabric was destroyed within 3 days of wearing it. Either getting caught on the loop side of velcro packing it in & out of my bag, or leaning against a slightly rough stone wall, the threads from the material would get snagged & then ended up as pulls in the fabric & fluffy bits that wouldn't go back.
Not robust enough at the price for a 4 day bike trip, that's for sure! Maybe ok for playing badminton somewhere really hot, or a long run if you're never going to end up climbing over a stile or leaning against a brick wall. Otherwise find a different kind of superlight technical fabric because this one is far too delicate & needs to be babied throughout use if it's not going to get destroyed really quickly.
