Yeah, I was going to get the Hydrapak. It would definitely fit with the Dakine pack, but after seeing that test, I'd rather get something more durable.
I just got the 100oz Camelbak Antidote, and it's nice! It's pretty low-profile when filled, and doesn't have a slide seal at the top that could rupture with too much pressure.
Also, because it doesn't have a twist-to-open valve, it's easier to use with one hand. I haven't tried fitting it with the pack yet, but I also bought one of these straight valves with it in case the 90-degree standard valve doesn't fit in the hydro sleeve:
Looks like I'm good to go then. Thanks for the advice.
