A purely functional and lightweight baselayer made from merino wool, simply the best material you can wear next to the skin. This is a damn good baselayer for active, demanding use.

• Active fit: snug and comfortable.
• Raglan sleeves: no chafing seams on the top of the shoulders adds comfort when carrying rucksacks.
• Flatlock seams: no thick folds that could cause discomfort.
• Long hem: the hem is longer at the back to keep it safely tucked in when moving about.
• Velcro for Finnish M05 rank insignia on the left sleeve.
• 80/20 merino wool/polyester, 180 g/m² / 5.3 oz/yd².
• 19.5 micron.

L1 - Base Layer

The first layer of the Särmä TST clothing system, tasked with moisture management. A good next-to-skin base layer keeps you feeling comfortable in all conditions. To do this, it needs to be lightweight and effectively moisture-wicking. We use a lightweight merino wool blend for our base layers, a natural and very functional material for this purpose.

High quality Merino wool

Made from 80% merino wool and 20% polyester, weight 180 g/m2 / 5.3 oz/yd². The polyester content adds abrasion resistance to the otherwise quite weak wool. Merino wool is a fantastic choice for next-to-skin wear. Most notably it feels good against the skin and retains its insulating properties even when soaking wet.

Mulesing free! All our merino wool products are made using mulesing-free certified merino wool.

Made in Lithuania.

Wash and care

This merino wool blend is machine-washable at 40°(104°F), but washing is seldom necessary - wool cleans itself. Don't leave these in a wet lump after washing. Reshape them gently while still damp. When not in use, air them out and give them a good shake after that.

Sizing

In addition to the simple size, we added the recommended height, chest, and waist measurements. These are quite form-fitting; by picking your size, you will get just that, but these do stretch a bit. Pick a size larger if a bit looser fit is required.

Our model's measurements are about 175 / 96 cm (5' 9" / 38"), and he is wearing the size Medium..
