RSGLike the ability to see how much fluid I've got left. Loses 1 star as the valve is a little stiff to open with teeth. Good value though.
Mr BrettWhy pay more? Great bottles with handy measure guides. Proven to be durable and do not hold old taste
Mr RollinsBasic bottle, useful measurement marks. Does the job
ChristopherGood quality bottles. Plastic is relatively soft making it easy to squeeze fluids out. The lids fit tightly and have a good seal preventing leaks. The openings are quite a tight fit as mentioned by others but I've not had any issues opening and closing when on the move. Overall I would recommend these.
Mr SimmonsGreat bottle as expected
Mr DixonQuality bottle should last a while.
C HTop quality bottles
Simon McCormackGreat product & price to match.
Mr Simpsonstill my favourite water bottles
webikerestricted space in bike frame so got the 600ml , quality is good
Folding GarethWide lid makes for easy filling and cleaning
Mr KhiewGood value and quality.
Mr ChapmanI've got a few of these bottles now and all but one of them are great. One of them started leaking from the lid after a few months so I get water down my front when I tip the bottle up to drink. That might be refreshing in summer so I won't complain!
chris bGreat value

Mr JenkinsonGood quality bottle at a great price
Mr TowersDo what it says with useful measure for SIS products on the side. Not a hint of a plastic taste either !

MarkGreat quality, love the yellow version. Best price on the net too.
Simon WGood bottles for the price (Merlin's is competitive - Wiggle don't seem to be stocking the yellow ones anymore). Tops don't leak and they fit well in my bottle cages. Re-order as the kids keep losing them or chewing the rubber pull-tops!
Dung NguyenIt's good and clear so I can see water in the bottle and it is fit with my black bike. Thanks

Mr DoumaGood product. Easy to drink and opens easy.
lyallI purchased a 1 litre bottle last year. I was using it so often I bought another one.
Mr SpurrNice bottles. I use elite normally. These seem just as good. Slightly thinner case but all high quality material. Easy to open and close on the move. Nice large capacity for when tool bottle takes up the second.
DKLove this bottle! I got the yellow one to match my bike. Not too soft but just right. It works perfectly.
Mr SchembriGood quality bottle. Thicker than some of the cheap and nasty bottles, so I'm sure will be durable

Mr tomlinsonGreat bottles and excellent value
Mr SoutarUsed this for years. Perfect

NestorThe best one-liter bottles made (of very few) for cycling
Mr JenkinsGreat bottles, super price. Very easy to clean
Mrs RothwellGot loads of these bottles - very useful and good price.
ToneWas looking for some 1lt bidons for long rides and these are great for that. Easy to squeeze with a tiny bit of spillage now and again. Saw many riders in the Indian Pacific Wheeelrace using these so thought they can't be too bad.
Mr López SuarezI already have other ones. I purchased a new ones because of usefull transparent plastic and variety of capacity
SimoExcellent quality, the large opening allows easy filled with electrolyte powder, 1 litre model still fits a standard cage
Jersey socksHave bought many of these SIS bottles, great for the bike, gym, travelling , whatever. Easy to use.
stephenI bought the one litre size as I was doing a 100km ride with lots of hills in the heat. Worked very well. Easy to hold and pull out of water cage. Easy to drink from. Make sure you give a good rinse before you use them as I needed to do a couple of quick rinses before use to get the plastic smell out but after that, it was perfect.
Dave KIts my favourite bidon/plastic water bottle as the lids keep sealing for years!!! And the logos don`t scratch off too quickly.
PriceMy bottle of choice and a good range of sizes. Hold up well over time and easy to clean.
RiceThey're bottles. 500ml is right at the top of the SIS "band." I mention this because it is not stated. If you are using powders, the markings are great. When using tablets (like me), any 500ml bottle will get the job done. They don't seem to leak any more than other bottles but the valves do take some time to "break in."
Mr PhelanGot the 600ml wide mouth bottle. Does exactly what you expect and the wide neck makes it easy to add whatever powders, etc you want.
Mr HaeuslerNice big bottle for those long rides. Its big though so may not fit in all frames. Ok for my road bike but does not fit in the MTB
BurgessWanted a couple large bottles for those long rides and the 1000ml versions are perfect.
Mr JordanI've got 2 of the 800ml WIDE neck bottles. The wide neck provides easy access to put in drinks powder and easier cleaning. There is no odour or taste from the plastic and they fit securely in my Elite bottle cages.
Mr AYAZBottle quality is ok. When you put water it is not smelling of plastic. And looks good.
HugoInsulates decently, wish I got the biggest size available
ALBALLAAEasy to squeeze
Mr MulvaneyThese are great. Have to buy some more. One of the few bottles that has a nice wide mouth and nice and clear so can see whats left. Also slightly bigger small size ie 600ml so for me these are ideal.
Mr MorganI got the Big ones. BIG-Both in volume and the ability to swallow the biggest ice cubes without hesitation. I washed them out with soap and water, then baking soda/water mix for a day and they had no plastic smell nor taste.
Mr MosleyEasy use bottle for mixing your drinks correctly
Mr RileyGood quality bottle, top fits securely, no leaks. I had a SiS bottle before this one which lasted me for almost 3 years. So far it feels like this one could do the same. Very pleased with the purchase.
Mr HendershotThese bottles look great on my bike. I love the narrow neck they have.
Mr WilliamsExcellent bottle, durable and doesn't leak. Happy to find the large version with a wide top
Mr DunnettThe wide top option is perfect for powder energy drinks etc. No more waste and sticky mess down the side of the bottle. They also don't leak like some at twice the price.
Mr PrenzelGood size, easy to fill and drink out of.
Mr StewartNice wide neck for putting in drinks powder. Solidly closing bite valve. Good value for money - SIS bottles last for ages.
Mr ChapmanThis is the second one I have purchased. Nice bottle with a wide neck.
Mr NorcrossIt's a water bottle, it does not leak, it works. Great value.
Mr StoneIt's a bottle. Easy to squeeze, measurements on outside useful.
BarryNot a lot to say about a water bottle but these are definitely one of my favs. Robust and very comfortable and functional top.
Mr BirdThis is a good bottle which fits into the cage that I bought, the elite custom race resin bottle cage, it doesn't leak when you go over bumps.
David MorrisNice bottles. We use them for hiking etc, and they don't leak that much.
Mr GonzalezGreat water bottle. Easy to drop into bottle cages while riding, and no hassle getting it out.
RichardGood price, good bottles, good soft nozzle.
Mr ÅgrenEasy to drink from, easy to fill up! Does smell alot and without a real cleaning the water taste "plastic".
Mr ClarkGot the biggest bottle. Stores a litre of water which is good, but it is a little unwieldy. On reflection I would go for the 750ml bottle. Easy to drink from though.
Mr BrookesGreat bottle, and wide neck means you can get the powder in the bottle and not on the table top. Flexible so you can squeeze for quick gulp! Would buy again for this price
Mr BiggsOpted for the small bottle, great for using on a smaller road bike frame where the larger sizes can catch the frame and make them hard to remove. Good quality and cheap as chips!
AndrewValve was a little stiff to start with but soon loosened up. They look good and are easy to squeeze. Excellent value at this price.
M SissonGreat bottles. Like the soft-squeeze cap. Used them a few times now and no hint of a leak. The measuring marks on the side are also handy for making up your carb drinks.
Mr BayleyStruggled to find many 1L bottle for the road. This one is good. Wide neck makes it easy to fill and mix powders in if you want.
Dr GillespieVery pleased with the bottle. Went for the middle size which sits perfectly within a standard cage. As always, the delivery was sharp - can recommend.
Australian Customer* Awesome quality * Fuctions well * Is transparent so you can see liquid level * Looks great on bike
Mr BurkeGood bottles, no problems. They fit well in my Elite cages, firm but not too tight like some other bottles I have that are really hard to extract.
Mr WrightExcellent all round water bottle good price, easy to open when riding
Mr PalhoniI recommend everyone to use this product. The nozzle has two opening stages. Very good. Product shipping was fast and safe
Mr ValdiviaVery nice product, easy to use and the colors match my bike. They keep the water cold and that is a plus in hot weathers.
Mr CliffordI've had a few of these and did prefer the red but qulity is more important than colour and the 800mL size gives you that little bit more range.
Steve W.Smallest size bottle is perfect for a junior MTB where frame space is an issue. Usual perfect service and fast delivery.
Mr LyonQuality bottle and great Merlin price as ever. What more can I say other than I would highly recommend.
Mr HudsonThe best bottle out there why pay more. Good enough to put in dishwasher and light enough to give a good squeeze
Mr GwytherSolid wide mouth bottle with fill markers for SiS powders. Logos and markers much more robust than some previous versions of these bottles which wore/washed off very quickly.
Mr DaviesGood value bottles and fits snuggly into most bottle cages
gmkGreat bottles at a very very cheap price. soft nipple for biting whilst riding.
Mr HawkinsDecent bottle for the price but plastic is easily discoloured by some isotonic drinks and logos do rub off very easily.
Mr Kolmakovgood bottle, but not very pretty
Mr hastongreat servie and product at a good price used this make before never had any problem
Mr simpsona good quality bottle at a good price
Mr RobertsNice bottles. Easy to keep clean due to the removable mouth piece. Bottle measuring/labels on the bottles wear very easily though.
Mr BeaumontHandy graduation on th side of bottle for ease of weighing out supliment powder
