Merino icebreaker.


The best thermal shirt is the second I buy, the first is the model with a high neck and a zip. It is a slightly more sporty model but this one is more versatile.

The T-shirt is very pleasant to the body. Decently oversized, I usually wear size M, here it just turned out to be S.

The Oasis 200 by Icebreaker is totally recommended for any outdoor enthusiast. Is super warm, non-itchy, odor free and great feel on skin as always with merino wool.

Very good and warm base layer

Very comfortable and warm


Extremely comfortable and warm shirt. Provides adequate warmth when outdoors during cold winter days in Finland. The most comfortable baselayer I've ever worn, well worth the money. Fits as expected, I recommend checking Icebreakers own size chart.

Top fit, collar and material!


We pay a little more than another brand (Odlo for example), but we receive the top of the top of the long-sleeved t-shirt in merino wool: a cut close to the body but not too much, sleeves of the right length , a collar that is not too tight but not wide either, and all the advantages of merino! I weigh 178cm for 72kgs and size M is perfect!

Comfortable and breathable


Used as an undercoat when riding a bicycle. It doesn't become sticky with sweat, and the warmth is perfect.

175 cm size m perfect


175 cm size M perfect. Cool and warm the same time. I recommend for cool weather as tried.

Nice quality


Lovely warm bottom layer that keeps you warm when you are working outside. Does not itch and stays beautiful in the wash.
