Welcome to Arzarf!

Our primary goal in creating the Arzarf was to help everyone get a better grip. Even the best insulated water bottle can be a nuisance when your hand is too slick to grasp it well! That’s why it was important to get the texture just right. 

We wanted our water bottle sleeve to give you an easy way to get a firm grip, no matter how sweaty your hand may be. Likewise, the depth of the ridges on our silicone sleeve, combined with the gently squishy texture, was designed to help little hands get a grip on big bottles. Give your toddler help drinking from a big ol’ Hydro Flask, and more! The combination of ridges and silicone sleeve make it as easy as possible for anyone to get a better grip on better hydration.

The idea for the Arzarf was inspired, in large part, by the cardboard sleeve that goes around disposable coffee cups — as well as the traditional zarf that inspired those. We designed our silicone sleeve to serve the same sorts of purposes. On top of creating a better grip, the Arzarf bottle sleeve offers protection against hot and cold. 

We made the Arzarf to handle both freezing and boiling-hot temperatures because that’s what people need. Arzarf silicone sleeves are great for keeping your hands protected and providing a bit of insulation for an ice-cold bottle of beer or a frozen water bottle. When the temperatures drop, enjoy your toasty warm cup of cocoa without scalding your fingers. 

We know that a lot of Arzarf users live an active, on-the-go lifestyle, and you need gear that can keep up. We rigorously tested our water bottle holders to make sure they could keep up. They’re waterproof, by dint of the fact that they are made from silicone — so there’s no need to worry if your water bottle takes a tumble while kayaking or paddle boarding. 

On top of that, we took the time to test different compositions in order to make sure that the overall durability would stand up to wherever your adventures take you. Our silicone bottle sleeves are made to stay strong if you happen to drop it, or even if your toddler decides they want to toss your water bottle across the room repeatedly. We expect plenty of folks to grab their Nalgene or Yeti for a day of mountain biking — and our silicone sleeves are made to handle those rough-and-tumble adventures. Basically, one is made to last through a lot of use, making it a heck of a lot more durable and sustainable than a disposable coffee cup sleeve. 

We know that everyone has a different definition of what makes for the best insulated water bottle — or thermos, or glass, or whatever your preferred receptacle is. Arzarf silicone sleeves are flexible without being one-size-fits-all. We worked for the perfect balance between “stretchy enough to fit a wide range of bottles” and “not so stretchy it will slip off or fall apart.” Use the size guide to find the right size for your favorite water bottle and trust that there is just enough stretch to keep the Arzarf where you place it, no matter where your adventures take you!
