CamelBak Racebak Hydration Jersey - Men's - 2009 BCS

Very interesting, I would say it wouldn't work though. As wetsuits are skin tight, it would just tend to push/pinch the water up, possibly creating a pressure point for you. You could try it, if it ends up being too complicated, just return it or use it for running or biking or something.

It is designed pretty much for your needs. Personally I feel that it limits your options overall (read: lack of storage for a shell), but does cut back on weight and drops the hassle of a pack moving around on your back.

This camelbak is recommended for two hours of exercise. If you're canoeing for 6 hours, you'll need to keep refilling this 3 times. Camelbaks are handy for carrying the water, but not very efficient when it comes to refilling the bladder.

Tony,
I'm an avid canoe racer and prefer to secure a bottle inside the boat unless I'm getting in and out a lot like in adventure racing. But then I'll wear something like this AND secure a bottle in the boat.

I'm sure that it would probably work. However, this system is really for people who are running (or on a bike), to make it easier to carry and access water. If I were in a canoe, I would probably rather have my water in the canoe, rather than having to wear it (unless it were a non-stop race, where this system could have some advantages).

i have a 3L camelbak and it doesn't slosh... you need to remove all the air out of the bladder after filling it up. i just turn mine upside down and gently squeeze the air out until water comes out the mouth-piece

Mid-flight refueling is totally a possibility. Aircraft sold separately.

you should go large, as these are tighter fitting.

I mountain bike race with one here in the Northwest and find that using the Raceback is cooler than wearing a pack, especially when I pre-freeze half of the bladder full of water. ( I fill it up half way, blow it up with air, lay it flat in the freezer so the hole to the tube is clear of the water ) Then fill it the rest of the way and have cool water and cool back.

I prefer to avoid wearing anything besides clothing on my back when I'm riding. Water bottles are fine and the water bottle carrier also carries a coffee cup nicely as well.
