ELITE Jet Biodegradable MTB,

Bought 2 - great large cycling bottle but the lid hinge is quite fragile and already snapped off 1 of the 2 lids. Still useable but don't expect it to last long.

Useless cap cover - broke off even before I has used the bottle on the bike.

A good big bottle. Transparent so you can check it's cleaned well after use.The tricky thing is the cap. It's good because it completely cover the mouth piece. When you are cycling in rain on grimy road or dry and dusty, the crud gets all over the mouth piece which goes into.. well your mouth when you drink. This completely covers the top of the bottle, so stops the crud getting any where near the mouth piece. However the way it hinges, is attached to the bottle and seals all seems fairly flimsy. So while it hasn't broken yet it's bound to at some point.Contrast that with the silicone small cover for a camelback.. that grips the mouth piece well and doesn't seem like it'll suffer the same use break down. However it is small only covering the mouth piece rather than top of bottle. On balance for it's durability and easier use, I prefer the camelback. But other may find this complete cover a better solution...
