Very warm while being very light, I don't sweat with it and this t-shirt is super comfortable

The T-shirt doesn't warm as much as I expected, but it's probably the size, there aren't many to choose from. The seam across the belly and chest is uncomfortable.

Very comfortable and very warm

Nothing to complain about, the product is comfortable, it keeps you warm and the pockets are practical. The same goes for the thumb straps which are also very practical.

Very good long-sleeved shirt for sleeping in a tent or cycling on a hike

Excellent t-shirt. I wash it by hand and in the washing machine on the 30° Wool program. I dry in an AEG dryer, Wool program. The T-shirt does not shrink even after many washes, it keeps its shape. (the entire washing and rinsing process must take place at the same temperature, if you wash at 30°C, you must also rinse with water at 30°C, cotton programs do not do this). Sometimes I put it in a bath with lanolin. The only caveat is the length of the sleeves, which is too long. Perhaps it is an intention to thermally seal the sleeves of the jacket.
