Not very fit, struggle to drink while panting like a bulldog and I need a new water bottle – biggish (750+ ml)

does any type have an easier "valve" than others (or is more easy-squeezy ?)

Also, what about camelback etc – who makes the fastes flowing valves (I have a bladder & tube but hydrapack bite valve is sloooow) – CRC have something that looks just like an inline tap, coulod I use that without a mouthpiece at all ?

Thanks in breathless anticipation

spooky !

just opened my email to read about camelback podium bottle with a high speed jet-flow valve

is that worth an extra fiver, I wonder….
