Science in Sport(SIS) Cycling Water Bottle Team Grenadier Fly Blue 550 ml, 130859, Plastic

Good product, it does the job. You can shake it with the lid and cap on and it wont leak. The plastic container part of the bottle is quite rigid so it can withstand reasonable bumps and whatnot. SIS are good products and haven't had any faults with their products in the past. Only issue I have yet to overcome is when you put the protein powder in the bottle, and then mix it with water there is always powder residue at the very bottom to the sides. Its like it needs a mixer ball inside it.

Designed to work, not look like a fashion statement. Had a lot of lumps in the past no mattered what I tried and this just made that all history. Its quite incredible how well it macerates the contents up with just a quick shake.

Cheap and perfect for kids football training

It’s a mixer. It mixes ok with the sieve insert. But you can barely read the levels on the side - ie the important part!!!! Some black ink on that part rather than just the product name would have been helpful.

One seems OK and not leaking but bottle arrived out of shape so wobbles a lot on a flat surface.Other in shape but leaks.
