Svala Merino Extreme O-Neck Base Layer Set

We doubt you'll find a higher quality base layer than this: Merino Wool Extreme from Svala. The shirt features an O-Neck crew collar, set-in sleeves, and an extended hem in the back.

Svala Merino Extreme base layers have a 2-layer construction: the inside is moisture-wicking polypropylene and the exterior is warm Merino Wool blend with a bit of polyamide added for durability. This design keeps the skin always dry and warm: moisture is transferred away from the skin to avoid "evaporation cooling" even when you stop moving. The natural anti-bacterial properties of Merino Wool keep the garment fresh day after day.

All seams are flat to prevent pressure points and chafing. Thanks to its long fibers, Merino Wool doesn't itch as ordinary wool often does.

This set includes the Merino Extreme O-Neck Shirt and Merino Extreme Long Underpants. These are available separately, in case you want the top and bottom in different sizes.

Size info

These are not ordinary sizes – pay attention to get it right! Beginning from the small end, the sizes run a bit large, e.g., if you normally wear a medium, pick the Small Svala. However, the sizes grow in small increments of 4 cm / 1.57" between shirts and 5 cm / 2" between pants, so the sizes upwards from XL are smaller than you would expect.

The recommended chest circumferences in the table are true to size. Following those, you will get a fit that stays against the skin as a base layer should. The measurement laid flat from armpit to armpit is pretty much half of the recommended chest size, e.g., a Medium (102 cm) is 51 cm from pit to pit. A slightly undersized shirt will stretch to fit with ease.

The waist sizes are the maximum we recommend. The fit is very close, so if you are exactly on the mark, you can even pick the larger size without any bagginess.

In case your measurements don't match the top and bottom of the set, you can get these separately without a price penalty.

Recommended body measurements

If you don't know your chest circumference for sure, just lay a nicely fitting shirt on the table, measure it from pit to pit, multiply by two, and compare. Note that the knit is stretchy.

The pant sleeves are made to avoid bunching when used by people shorter than average. If your ankles need coverage, use long socks.

Materials and care

Made of 75 % Merino Wool, 22 % polypropylene, and 3 % polyamide. The inside layer is moisture-wicking polypropylene, and the outer layer is SuperWash and anti-moth-treated Merino Wool.

All dyeing and finishing chemicals meet the ÖKO TEX 100 standard. All the Merino Wool is mulesing-free.

Thanks to its antibacterial properties, Merino Wool is odor-resistant and can often be just aired instead of washed. The product does not require washing before use.

When it is time to wash, use the wool program of your washing machine, preferably with a wool-specific detergent. Shape when moist.
