Guyot Designs SplashGuard-Universal, Aqua Camo

This works so well with my water bottle. They really stay put and keep my water from spilling everywhere!

Love this addition to my Nalgene type water bottle. Never again will I spill all over myself!

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.

I really enjoy the splash guard I bought for my Nalgene bottle. It fits the large opening perfectly and does exactly what its supposed to do. The first time I attempted to use it, I did push it down too far past the opening of the bottle which resulted in it falling to the bottom of my bottle but it stays perfectly in place just resting right on top of the opening. I have been using it every day for weeks now and have no problems. It holds up in the dishwasher which makes cleaning it super simple and easy.I've had my water bottle practically forever and although I do like its carrying capacity, I don't like how difficult it can be at times to drink out of. Especially if I am trying to drink as I am walking or doing some other task. The splash guard fixes that.Shipment was fast as expected. Overall a great purchase.

Fits into standard 32oz Nalgene

Before and especially after her kidney transplant my daughter has to drink a lot of water. A lot... So she carries this huge water bottle with her everywhere. She loves the wide-mouth bottles without complicated sipping spouts and/or some other contraptions that easily break or are hard to clean. One downside is that quite a few times she ended up spilling water on herself while trying to drink it during long car rides. So this little insert solved the problem! Personally, I wish it would come with the bottle as a set. And although it is a bit pricey to buy separately, it is extremely useful, easy to clean and very durable, so I do recommend it!

I'm SO glad that I found this handy little splash guard. I love my Nalgene wide mouth water bottle but I hated trying to drink from it without spilling or splashing water in my face...especially while moving. This wonderful splash guard solves all of that. It fits perfectly, stays put and keeps me dry. It's very easy to use, easy to remove for cleaning and it doesn't create any funny tastes in the water. One of the best purchases I've made in a while! I highly recommend this!
