A strong fold-out concertina bag built into a bottle lid which holds half a litre
BOTTLEBAG – fold out bag built into a bottle lid holds half a litre – suck to bring bag into cap and clip shut – would be great for camping and runners who want to stash their water bottle in a pocket when finished.
Like the idea, so do many on Kickstarter, I hope they make it.
good idea, they should make it out of liquiglide so you get every last drop.
