Science in Sport SIS Clear Sports Water Bottle, Plastic Water Bottle, Black Logo, Transparent Colour, 800 ml

I bought a couple of these water bottles due to the hot weather as the old one had had enough. A very wise choice. The bottle is durable and made from good quality materials. A very important thing is that it doesn't leak (I expected a trusted seal from SIS), so I'm very glad about this. It holds an amount which is enough for me and one session for hydration. Easy to carry and fits well into rucksack pocket and bicycle holder. Looks great and can see how much liquid is remaining. I haven't noticed any difference in taste due to plastic whether with water or fizzy drinks. Great for gym, cycling, walking/running, well anything really. Very pleased thanks guys.

A classic. Sturdy and reliable. Doesn’t develop odours. Easy to clean. Very easy to drink out of - not much squeeze at all is needed for a quick and full flow yet when the mouthpiece is closed it’s tight and secure enough to not have to worry about leaks in a bag even if upside down.

Great bottle for everyday use, and easy to use while walking or running. It does get leaky if you don't tighten the cap properly and some times when I in a rush id often forget that and end up with water running all over my shirt :(

I've been using the Science in Sport 600ml bottle for a week now and it’s become my go-to for both gym training and everyday hydration. The clear design makes it easy to see how much liquid is left.The bottle is lightweight, and the nozzle is secure but easy to open with one hand (or teeth). It doesn’t leak, even when shaken or squeezed and it’s easy to clean after use. Overall, it is a reliable and practical bottle. Highly recommend!

Good quality bottles that seem very durable and long lasting.Would buy again.

Great! Well worth having! Doesn’t leak, sturdy and easy to clean. So good I bought 2 more and have had no problems whatsoever.

Bottle is fine, but really annoying label stuck to it that is a pain to get off despite careful peeling. Unnecessary.

This drink bottle is cheap (£5 at the time of writing and now reduced to £3.75), plastic and simple. Indeed, there is no capacity markings on the side of the bottle (800 ml) and the sports top is disappointingly rather stiff to open and close if using your fingers. Of course, using your teeth to open will in time destroy the mouthpiece, if not your teeth! I am hoping that this mouthpiece will loosen a little with use. I do like the indent two-thirds up which makes this easy to grip and from which to hold to drink.Water leaks from this if the sports cap is left up but otherwise, turn it upside down and I did not experience any leaks.Purchased for hiking in the Madeira levadas, this was tested out initially in the gym and to my satisfaction. This is certainly suitable and capacious enough for my forthcoming hiking trip. It is a no frills sports bottle suitable for my needs.
