SIS Yellow Sports Water Bottle, Plastic Water Bottle, Black Logo, Yellow Colour, 800 ml [Design may vary]

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.

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.

The product functions effectively and meets its intended purpose quite well. However, one significant drawback is the rubber seal, which unfortunately does not perform as expected. This flaw allows water to leak through the seal, which can be problematic and may impact the overall usability of the product. It would be greatly improved if the seal were upgraded to prevent this issue.r seal, which unfortunately does not perform as expected.

Not had any issues with leaking or cracking. Easy too clean since it has a wide top. Works fine for the gym

Water bottles ey? Who would have thought it would be such a palaver to find the right one!? But I may have found it with this one: Nice squishy plastic (but firm enough), so it’s easier to squeeze the water into your mouth! Nice soft cap that you can open with your teeth so you can keep one hand on your handlebars. Nice little design (ridge) that enables the bottle to sit in a water holder with ease. Fits my Vico Carbon Elite perfectly!! Nice wide opening, making it easier to fill - and to fit ice in for those extremely hot days out! Nice price - I.e. relatively cheap so if something does happen at least you can get another one, without breaking the bank - and at a cheaper price than a more expensive bottle. BPA free! Which is a good thing. Flow rate is pretty good. The bottle is marked to help you measure out SIS supplements if you are using. Also…sounds a little odd to say, but when you need to quench your thirst it actually TASTES like water (if you have water in your bottle obviously - if you had Lucozade in it, it would taste of that!!). Some bottles can add a plastic-y taste to the water - this one doesn’t! I use a hydration backpack as well as this on a ride, and that definitely has a distinct plastic taste to the water! So it’s nice to get the pure taste from at least 800ml (probably a little more if you fill it right to the brim). Also as it’s quite squeezable - if you’ve got anything left after a ride, you can have a decent water fight with your mates! Onto the bad points; I’ve seen from other reviews that the bottle can get discoloured if you are using a coloured fluid in your bottle - this may be the case, but it doesn’t affect the use - so far mine has stayed the same clear colour due to me just using water. Also other reviews have stated that if you drop it on its head, you will snap the nozzle - my advice is don’t drop the bottle! Although if you do have butterfingers and it does snap it’s not a hugely expensive cost to replace. Overall a pretty good bottle and a piece of kit I will always definitely carry round with me when out on the bike! I tend to use this mountain biking, and the only thing I’d suggest as an improvement is probably a nozzle cover to keep the mud and stuff out of the nozzle, but this would obviously make it a tad harder to open on the bike. Would I buy this bottle again? Maybe, although probably not as since I purchased this, SIS have released a slightly larger 1000ml bottle in the same style - and I’d probably get that instead for that little extra hydration!

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!

This is my husbands choice in water bottle which he takes swimming and also when he works as a lifeguard. The bottle is a great basic water bottle and he only uses it for water doesn’t add anything into it. He had this same bottle a couple of years ago and it lasted well. This purchase was the replacement as the first one had started to leak slightly after a few years of use.

Good size. It’s ok. Doesn’t leak when stood upright. But the nozzle isn’t easily cleaned properly. Not a long-term purchase. Over time, the water becomes tainted easily no matter how the bottle is washed, even with bicarbonate and vinegar. Eventually, the water becomes evil tasting every day. The only solution is to throw the bottle away buy another. The water becomes tainted ones contaminated and the taste is bad daily.

Ottima borraccia a un prezzo accessibile. Leggera e facile da usare anche per bambini durante lo sport. È facile da pulire e il materiale sembra resistente. Consigliata

Ürün kaliteli ,bisiklet sürerken akıtma yapmadı, gayet şık ve güzel.

It does the job. 😊

for the bicycle it gets dirty where you drink, so not ideal. But overal good quality and does not get so easy scratched
