High quality product, excellent value for money.
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.

water bottle for sports.
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.

No frills sports bottle
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.

Wouldn't buy again
I bought two of these to take on holiday during the hot weather to save buying bottles of water every two mins. One was absolutely fine but the other one the lid didn't fit properly which meant the water leaked all out the side as soon as you tipped which my mum discovered after she filled it and went to take a drink and got soaked! It went straight in the bin! Id say it's 50/50 on if you get one that isn't broken!

Leak free and sturdy
🧴 Science in Sport SIS Clear Sports Water Bottle – 800ml, Transparent For a bottle that costs less than a fancy coffee, this SIS 800ml delivers excellent value for money. It’s lightweight, durable, and designed with athletes in mind—but it’s just as handy for everyday hydration, whether you’re at the gym, on the bike, or chasing toddlers around the park. 💧 Leak-proof confidence The standout feature? That push-close top. Unlike twist caps or flip lids that can wear out or loosen over time, this valve-style closure stays snug and secure. No drips in your gym bag, no mystery puddles in the car cupholder. It’s a small detail that makes a big difference—especially if you’ve been burned by leaky bottles before. 📏 Practical design Clear body for easy mixing Fits standard bottle cages and backpack pockets Dishwasher safe for hassle-free cleaning BPA-free plastic with a sturdy feel—not flimsy or brittle 💰 Verdict: At around £3.75, it’s a no-brainer. You’re getting a reliable, well-designed bottle that punches above its price tag. And with the push-top staying leak-free long after cheaper alternatives give up, it’s a smart pick for anyone who values function over fuss.

Used these for the bike leg of an Ironman race. They fit in the bottle cages well and they are easy to open with you mouth while riding. The optic yellow makes it easy to spot your bike during transition which is a nice added bonus.
