Black+Blum Insulated Bottle Bag, Slate

Meet the Black+Blum Insulated Bottle Bag – Slate, a lightweight and versatile carrier designed for hands-free hydration. Made from recycled PET fabric (equivalent to 2.5 plastic bottles), this bag is eco-conscious and durable, with a food-safe PEVA insulated lining that helps keep drinks cool.

No matter the bottle—water bottle, tumbler, can, or even a wine bottle—the adjustable drawstring closure holds it securely in place. A cleverly integrated side pocket offers space for your phone, keys, or cards, eliminating the need for extra storage. The reinforced adjustable strap adapts for shoulder or cross-body wear, offering comfort and freedom of movement on daily walks, commutes, or festivals.

Compact yet functional, it measures approximately 11.5 × 10.5 × 20 cm and weighs just ~4 oz (113 g). The insulated lining and water-repellent interior effectively keep drinks cool and moisture away from your hands or bag contents. Note: this item is hand-wash only and features welded seams to reduce drips, but isn’t designed to hold liquids directly inside.

Styled in a subtle slate-grey tone, it pairs effortlessly with other Black+Blum accessories—think matching Lunch Bag, Tote Bag, or Explorer Flask Duo—for coordinated, sustainable travel gear.
