Add a splash of fall to your hydration game. The Autumn Glow BotlSok keeps your bottle cool and dressed to impress.

Thermal Insulation Keeps Drinks Cold: Nobody likes sipping lukewarm water or a room-temp protein shake. BotlSok’s high-density neoprene helps keep your drinks colder, longer — whether it’s water, juice, or your favorite post-workout mix — all while keeping your hands warm and dry.
Stops Condensation & Protects Surfaces: Keep your hands dry and your surfaces drip-free with BotlSok’s fully covered bottom and cushy non-slip grip. No puddles, no table rings — plus, BotlSok helps protect your bottle from scratches, dings, and daily wear.
Designed for the Perfect Fit: BotlSok sleeves come in multiple sizes (12oz, 16oz, 24oz, 28oz, 32oz), each sold separately. This page is for the BotlSok for Nalgene Style Bottles. Made from flexible neoprene, it stretches to fit a wide range of bottles and flasks — from glass beer bottles and disposable water bottles to mason jars and heavy-duty reusable bottles.

Durable, No-Scent Material: Made from thick, fabric-coated neoprene with reinforced stitching. Built to stretch, fold, and handle whatever life throws at it.
Soft, Lightweight & Portable: Easily compresses to stash in your bag, car, or gym tote — perfect for hydration on the go.
Budget-Friendly, Eco-Friendly & Washable: 100% reusable and washable. Replaces wasteful paper towels or disposable sleeves — saving you money and reducing waste.
A Style For Everyone: With tons of fun colors and prints, there’s a BotlSok to match your vibe [literally].
