Bike bottles come in various shapes and sizes, but Cambridge based Passport’s Frostbright is, at first glimpse, a regular-looking plastic sport-top. However, there’s more to it than that. Aiming to keep your favourite in-ride beverage cool, there’s also a road safety take. I’m pleased to say that I’ve been impressed by it.
Solid bottle that keeps your fuilds pretty cool...All in all, good value for money.

"Overall, it's a decent bottle. Its thermal properties are good, it doesn't move around in the cage, and has a useful high visibility element – all at a decent price."
