I got the medium size for my partner with a body type of 1.67 - 60kg, it was a bit loose but she is very satisfied with the quality and convenience of the pockets.

I am for small but on the label it says up to 1.70 height, I am 1.78, so it constantly squeezes me in the crotch, no matter what I tried.. be careful. Otherwise, it is still in good condition, I take it to the woods and it doesn't tear, without pants inside, even though it is quite thin, you don't get cold.. just before you wear it, remove and reinsert the fastening mechanism, passing it correctly because it is wrongly passed from the industry..

For the money it costs, it's okay. As for the size, its fit is quite narrow, so to be alright, you might need to buy it maybe two sizes larger than what you usually wear. Especially in the crotch area, it's terrible. Very, very narrow.
