Look, it’s hot out there, so carrying more water than usual is probably a good idea. And Restrap has a new solution to load up with a bit of extra fluids on the go, thanks to new Soft Flasks. Essentially, a soft 0.5L water bottle made of the same material as the latest hydration bladders, you can stuff them in the chest pockets of hydration packs, or even tuck one into a jersey pocket to carry more water for long & hot rides. Then, compress it down to take up less space once you’ve hydrated.

Now, soft collapsible bottles are certainly not something entirely new. Trail runners, especially, have been using them for many years. And that’s where gravel and ultra-distance cycling picked up the whole hydration vest concept. We’ve occasionally used Camelbak flasks since they introduced them in 2016, and their multi-sport hydration packs even started including a pair of expansion flasks back in 2020. But more options are always better in our book.

And the new Restrap Soft Flasks feature a smart-looking cap and valve design that might make it possible to sip some more water without even needing to fully take the bottle out of the pocket. Or even make it a more versatile design that a mountain biker could drink from more easily without removing a full-face helmet?
