It's a supplier for e.g. adult baby clothing including sleeping bags. I've bought from there site years ago and there are some hints that the quality isn't any longer as good as it had been in the past.
The locking zipper option is interesting but from my point of view too expensive because you may buy the key locking zipper for approximately 3,50 €/pts. and I've paid approximately 5 € for the exchange of a zipper locally.
