Review: 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.
Review: 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 :)
