Discover the unmatched luxury and comfort of our T-shirt, crafted from 100% 15.5µm ultrafine merino wool. The exceptional feel and appearance of this fabric set it apart from the rest, making it the epitome of sophistication.

Our premium fabric is made using two-ply compact spun Italian yarn, similar to our popular 220-series. However, the finer fibers and thinner yarn result in a fabric weight of 160g/m2. This places our ultrafine merino T-shirt perfectly between our ultralight and superfine offerings, giving you the best of both worlds.

Experience the lightweight, luxurious texture of the ultrafine merino wool fabric, which makes it an ideal choice for layering and all-day comfort. Elevate your wardrobe with this exquisite T-shirt, showcasing the unparalleled quality of 15.5µm merino wool.

Our most luxurious 100% merino wool fabric to date. Made from ultrafine merino wool, with a thickens of only 15.5 micron.  The yarn is two-ply, like our 220 T-shirts, meaning that two thin yarns are twisted together to give a higher fabric weight and extremely luxurious fabric.

The natural properties of the wool makes the shirt stay dry, clean and fresh-smelling for weeks with no need to wash. It will keep you warm when it’s cold and cool when it gets hot - and then they look nice.


Our T-shirts have no visible chest logos or itchy neck labels, because feeling good is the primary intention. We focus on the product and our quality and design speaks for itself.


As the name suggests, this is the best they come. 160 Ultrafine is our most luxurious merino T-shirt to date, knitted from 100% 15.5 ultrafine merino wool with a fabric weight of only 160 g/m2, making it the perfect combination of ultralight and ultrafine and giving it an exclusive look and feel.

T-OSS 160U Ultrafine

Mario Gaab
Nearly perfect

The 160 Ultrafine shirt is from its execution the absolute perfect t-shirt. One of the best fits I ever wore with optimal balance between tightness and comfort. It is a little more tight than the 220 short. I wear M with 1,74m height and 74kg.
The material is outstanding, very nice feeling and it has a really slight shimmer which makes it a noble look.
Only downside for me is that after a year the black colour around the collar is fading. I don't have that problem on the 220 shirt. Don't know where it comes from. Without that it would be the best shirt I ever had.

Very soft giving a luxury feel

Used 6 weeks as undergarment below other long sleeve Loow/wool and/or a cashmere layer while travelling in cold climate. No washing during that time. Just bought 2 more 160U T shirts. Just travelling with a 26l backpack, thanks to nature's fabrics.

Best shirt ever. I got rid of 100 old shirts to now just own several LOOW shirts

I ordered my very first LOOW shirt in November 2015. Since then I only keep buying LOOW shirts.
Mainly because of the wearing comfort they offer and because it is much easier to wear a LOOW shirt a few days then any other shirt. My cotton shirts start smelling quickly, but the LOOW shirts in general dry very quickly and are easy to wear longer than just a single day.
The 160U ultrafine is the perfect every day shirt. No matter if you go for a hike or need a proper black shirt under a jackett.

Light as a feather. Warm as a quilt

A long standing fan of LOOW and yet again this product didn't disappoint. Team LOOW, it's incredible you can make wool feel so soft, so fine and the strenght and warmth qualities are second to none. Will be back.

Own less, but better

wear merino wool

Our T-shirts will be the new favorite in your wardrobe. Made with 100% merino wool (and yes, that means no synthetics at all) it’s silky-soft and a pleasure to wear next to the skin. Our T-shirts are the perfect match between versatile, durable all wrapped up in a classic design.
