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. Review: Merino tech - 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 ## Features - Midweight - Merino Wool Base Layer men set Available in: Lightweight = 165 g/m², Midweight = 250 g/m², Heavyweight = 320 g/m².

And what does 17.5 micron mean?** A: 17.5 micron superfine merino fibers are finer than human hair — too fine to feel itchy, even on sensitive skin. Standard wool (25+ microns) causes irritation; this doesn't. OEKO-TEX certified, tested against 100+ harmful substances. **Q: How do I wash and dry it to keep it looking new ? Will it shrink or lose shape?** A: Machine wash cold max 30°C, delicate cycle, inside out. Lay flat to dry — tumble drying permanently damages merino fibers. Store clean and dry; keep merino in sealed bags to prevent moths. Wear 3–5 days between washes — merino resists odor naturally **Q: Which weight should I choose — 165, 250, or 320 g/m²?** A: 165 g/m² — active pursuits, travel, spring/summer, 40–60°F. 250 g/m² — cold weather, most outdoor activities, 25–45°F. 320 g/m² — frost and low activity, 10–35°F, extreme conditions. Rule: the higher the activity level — the lighter the weight. **Q: Where does the merino wool sourced from and is this product certified?** A: Our products are made from Australian merino wool, RWS certified — independent farm audit confirming animal welfare and land management standards. Every component tested against 100+ harmful substances under OEKO-TEX Standard 100. **Q: Does it fit true to size?** A: Choose your regular size if you prefer slim fit. For more relaxed fit order size up ## Customer Reviews ### ⭐⭐⭐⭐⭐ Feeling dry in wet - a high quality base layer *by P***M on 20 November 2025* If you never tried merino base layer, you may not know what you are missing!
