I think Sette is pp's house brand. Kinda like Forte at Perf.
Then again, it's just a hydration pack, so what can go wrong.
Might also look at the Hydrapak (Blackburn Design) at Nashbar. They have a $60 one on sale for $30 (look for 10% cpn on this site) and it looks like it might hold quite a bit of stuff too:
