This is one of my favourite thermal shirts. Thanks to the merino wool, it keeps you very warm and absorbs unpleasant odours more slowly. It works great both as a base layer and as a shirt for everyday wear.

The shirt is nicely stretchy, and the material is less thin than that of many other merino shirts. The only issue is that the sizing comes up a bit small: at 1.80 m and 80 kg, I normally wear M to L, but here XL fits a little more loosely. Very good length that stays tucked into your trousers.

This is one of the best thermal shirts I own. Even though it is quite thin, thanks to Merino wool it keeps you very warm, and the ventilation panels do an excellent job of wicking away moisture during intense exercise. The workmanship is of a high standard, and after washing I haven't noticed any shrinkage.

Great T-shirt. I have quite a few different thermal tops from various brands, but they’re not always comfortable – often it’s down to the cut or the material, which can be too tight. This T-shirt is perfect: very comfortable material, not too tight, and it keeps you warm. I use it for motorcycling, in the mountains, or skiing. I definitely recommend it!

It is warm, comfortable, and lightweight. It packs easily and does not retain odours even when you sweat or get it wet. It works well for several days – it really is airy and breathable. I definitely recommend it.

Size L fits perfectly for height 1.77 m, the jacket is very warm, does not irritate the skin, first impressions are definitely positive. I'm curious to see how it performs during a mountain trip.

Combined with leggings, this is a very good series of thermal underwear. Merino wool provides excellent insulation and a pleasant feeling of softness, while nylon strengthens the material and increases its durability. The product copes very well when washing.

The thermal shirt from FreeNord is an excellent choice for those who value high quality thermal clothing. It is warm, lightweight, comfortable, and takes up little space. It doesn't itch or squeeze. Highly recommended.

The shirt is made from a nice-feeling and attractive material. It’s elastic and fits the figure well. I recommend choosing a slightly larger size. At my height of 180 cm and weight of 90 kg it fits just right. I recommend it.

The thermal shirt from Free Nord is worth recommending – it maintains the right body temperature very well. I encourage you to purchase this product.

I bought it some time ago and I can say that it was a good purchase. It's lightweight, comfortable and pleasant to wear. There are no prints and it is made from high-quality material.

Considering its thickness and weight, the shirt (like the leggings) works really well. The fabric is rather thin, but thanks to the nylon, it is durable and resistant to damage. Merino provides good thermal insulation.

The thermal shirt without printing is a perfect option for those who like simplicity. Great material, careful workmanship and comfortable to use make it one of my favourite shirts!

The Free Nord thermal shirt is a purchase I can highly recommend with a clear conscience – it provides exceptional thermal insulation. It is definitely worth buying.
