Great but...

Delivery was fast, but the package arrived two days late due to a problem with the Post Office. The packaging arrived intact. We'll get a second one, which is very convenient.

Rather impressed

I'm impressed! Excellent outer material, with inner lining and separation between the upper and lower parts. On the semi-rigid side, the belt is not structured, but the weight distribution is effective and comfortable!

Alright

The backpack is great. It's large, has multiple compartments, and back support. The only downside is that the zippers were all open. Otherwise, nothing to report. Thank you, Antoine T.

Very good quality. I am very satisfied with this sleeping bag. It contains a good amount of down and the zippers are of good quality. Perfect size. I am 1.89 meters tall and it is very comfortable for me.
