Passport Frostbright Reflective Water Bottle



Good thermal bottle, though you do need to squeeze it harder than most

At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

The Passport Frostbright Reflective Water Bottle is a decent bottle that sits well in cages, is easy to use, and keeps cool drinks cool and warm drinks warm. It could perhaps be easier to squeeze, but all in all it's a decent bottle at a decent price.

The first thing you notice about the bottle is that it has been designed with reflective qualities in mind. It has a clear outer layer of plastic, but inside is a high-vis material with snowflakes on. It works too – when light shines on it, it really lights up well.

As well as being high-vis, the bottle is thermal, keeping drinks cold or warm. It worked relatively well at this – I put in cold water and it seemed to be around the same temperature a couple of hours later. It works with warm drinks too, but a bottle full of tea isn't really what you want this time of year.

The shape sits well in bottle cages – I didn't notice much movement and it was never close to popping out.

At the top, it has a traditional screw-on cap and the nozzle is a simple push up or down affair. Both work well, and the nozzle is made from a relatively malleable rubber, which doesn't leave any kind of taste in the mouth.

It isn't the easiest bottle to squeeze, probably because of the space between the outer clear plastic and the inner, where the liquid is held. I had to squeeze it considerably harder than most other bottles to get the same amount out.

As for price, its RRP of £11.99 is very reasonable for a thermal bottle. It also comes in silver and red, blue or black, so you can probably match it to your bike, if you're into that kind of thing.

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. I'd like it even more if it was a bit easier to squeeze.
