Guyot Designs SplashGuard-Universal

Do you ever spill half of the water in your water bottle all over your shirt and pants, making you look like an incapable child? Do you ever want to take a sweet sip of water as you're walking to class, but instead end up choking/almost drowning because a tidal wave of water came right at you when you tried to swig the bottle up too quickly? Do people ever look on at you with sympathy as you attempt to explain your situation of being the owner of the widest-mouthed water bottle in the existence of mankind?Looks like you need a SPLASHGUARD! You'll be glad you did.Never again will I look like an clumsy oaf walking around with a huge liquid stain down the front of my shirt and pants. Gone are the days of almost drowning when I try to take a cautious swig of water when I'm trapped in bumper-to-bumper rush hour traffic. Sure, the thing smells a little rubbery when you first pull it out of its little baggy. But give it a quick wash, plug it into the mouth of your bottle (it fits as snug as a bug in a rug), and bring it up to your own mouth for the most satisfying, thirst-quenching drink of your life. Prepare for that day, because you will never forget it.

These should be standard issue. I pop a spill guard in each 32 oz. Nalgene I buy. The yellow "smiley" guard doubles as a motivational device.The guard is designed for the standard 32 oz. bottle so make sure your bottle's mouth is comparable. It fits snugly—like a plug—and works as designed: The divot cut from the circle lets water pass.For cleaning, the guard easily pops out without degrading its seal. My brother pops the guard into the bottle and shakes it with soapy water, though I recommend a more rigorous scrubbing.

SERIOUSLY this is a game changer for drinking out of Nalgene bottles! Before I got this super cute Smiley splashguard if I attempted to walk and drink from my Nalgene I spilled on myself at least 50% of the time... I never do now! lol ... but seriously, you don't even realize how awkward drinking is out of a Nalgene until you get this and discover the ease of drinking! LOVE LOVE LOVE it! I recommend them to everyone I see using a Nalgene!BTW I have had like all of the Nalgene styles (small opening, flip top opening....) and I think the traditional wide mouth with the guard is the best.

After getting splashed numerous times, I decided it was time for a SplashGuard. Very happy with this product! It fits my 48oz Nalgene perfectly & does exactly what I need it to do. The diameter of the SplashGuard measures about 2in, give or take a little. These are designed to fit most wide mouth bottles. I love that there are plenty of color/design options with these! Would like to add a few more to my collection, just for fun. :)

fits perfectly, only problem was the "clean air" color that is completely misleading. The photo clearly shows an aqua/light blue color, but when i opened the package it was completely white. Don't trust the colors you see here. other than that it was great, so if you don't mind the color, i'd say go for this one.

I've only been using this for a day, but it's been a crucial purchase for me. I'm a little clumsy because of my carpal tunnel (and just naturally too), so often my shirts would end up getting more of a drink than I did. This addition to my waterbottle makes drinking so much easier.Only gripe: The Clear Air isn't blue. It's a cloudy, opaque white, which ended up actually being a good thing for me. I'm much happier with the white one instead of some of the other options sold here. It would be nice though, from a consumer end, to know that I was getting a white one instead of a blue.But, it's a $7 piece of silicone that does its job and the color honestly does not weigh too heavily on my enjoyment and relief when I can actually take a Sip and not a Spill.Oh, yeah: I have a 32oz Nalgene.

These guards are great. The 'vent' hole at the top allows your water to flow without 'chugging'. It's why you poke two holes, not one, in a can of soup or motor oil.My only issue is that I ordered the colors Mango and Orange, because the Mango looked more yellow in the photos and I want to be able to keep them separate while still somewhat matching our Nalgene bottles, one with orange, one with yellow accents so my husband and I can more easily tell our bottles apart on the go. What I received was two Mango guards. That's okay, but be advised they're probably actually the same, or I was shipped a wrong item. (They're aren't currently the same price, though.)Now I'm trying to decide whether to order a yellow one, but that smiley face would bug me when I'm running up a rocky trail and swearing at it.... :-p I'd love to find them in more solid colors without the printed designs.

Works perfectly for the normal wide mouthed Nalgene bottles. The 'sky' color is actually whitish in person, and doesn't have a blue tint that I can tell. The only issue is that it smelled as though it had been stored inside a bag of mentho-lyptus (the blue Halls flavor) cough drops prior to being shipped, and the smell (thus flavor imparted to the water) was quite strong.. Very odd. I put it in boiling water for a few minutes which reduced the scent significantly, and it's only a little discernible now, so that's fine. Good product though.
