I am 172cm tall and weigh 51kg. I bought a size small, and it fits perfectly with my protective gear underneath. I prefer a snug fit, and both the length of the pants and the jacket are just right for me! The jacket has an extra layer of thin cotton, and the inner pocket for my phone is quite spacious! There are also small square pockets on the sleeves, which is very practical. The clothing has drawstrings for adjustment, and while the pants don't have cotton padding, they do have a fleece lining inside. The snow protection is also quite high, and there are plenty of pockets, which are very useful. Overall, it's fantastic!
