Arzarf makes silicone grip accessories for insulated water bottles, tumblers, and more. They fit a variety of bottles including Nalgene, Hydro Flask, Yeti, EcoVessel, Klean Kanteen, Miir, Pelican, Stanley, and so many more. Reusable bottles are an important step in minimizing our environmental impact and reducing single-use plastic proliferation. Arzarf makes it easier to use those reusable bottles, especially when a user has gloves on, is sweaty or wet, or has small hands - like kids! Arzarfs make the perfect every day accessory for your insulated bottle, too.
