Science in Sport Sports Bottle, Yellow, 800ml | BPA-Free Leakproof, Ergonomic Design, Reusable Training Bottle

Excellent sports bottle and great quality. I use this at work and the gym! Quality is excellent and will no doubt last a long time. You won’t be disappointed.

I’ve purchased three of the Science in Sport SIS Yellow bottles, and they continue to impress me every time. The bright yellow colour not only looks fantastic but also makes the bottle incredibly easy to spot, whether it’s in the gym bag or attached to my bike—no more rummaging around or losing your bottle during a busy session. One of the standout features is the waterproof and leakproof design. Thanks to the secure, lockable valve, I never have to worry about any spills in my bag or car—these bottles keep every drop where it belongs, even during hectic cycling or gym workouts. The flexible yet durable plastic copes well with drops and daily use, so it’s built to last and still feels comfortable to squeeze for a quick drink. The ergonomic shape makes it super easy to grip, and its flexibility is perfect for sports and on-the-go hydration. The bottle also features a wide neck for easy filling and cleaning, plus clear measurement markings, which save time when mixing up energy powders or electrolytes. After trying many different brands, I can honestly say these bottles are some of the best. They’re reliable, flexible, and their yellow colour makes them stand out from the crowd—a great choice for anyone who values both function and style in a sports bottle.

Does what it needs to and doesn’t leak. Slight criticism would be that the top doesn’t open easily.

Great value, works well

SIS bottles are always my first brand to buy!! Last for years, highly recommend!!

Just what I needed

Always good quality water bottles and easy to clean had a few of these now and last a while even being used up to 4 times a week at football

Looks decent and for £5 i cant complain, well maybe 1 complaint ia the smell inside the bottle, I've washed it thoroughly and with baking soda and the smell is still there

€4 each for a bottle was great deal on at the time. Relative drinks heaps of water & bedbound so 6 =€24 delivered :)

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.

Superbra flaska (800ml). Läcker inte och rymmer lagomt med vatten eller saft att ha på jobbet. Köper igen när jag behöver fler. Uppdatering 231118 - upptäckt att den läcker vid gängan där man skruvsr på locket. Mejlat reklamation idag då den inte var möjlig att returnera/återbetalas. Får se vad Amazon svarar.

bonne qualité et ne fuit pas

Does the job.
