Very smooth, efficient and fast! I have also returned one item due to sizing and the exchange happened fast. I was able to travel to Helsinki with my new thermals and was warm and cozy!

The sizing charts of some items are not to precise. I bought NB leggings in XL because it was the right one according to my personal measurements, but it was extremely big in person and I had to exchange it with L which according to your sizing chart would not fit me. Even the L is roomy on me!
