The Black Blum Explorer bottle is designed for adventurers! Specifically created for hikers, climbers, and all-around explorers, this ultra-strong, mold-resistant paracord can be used to carry the bottle or easily attach it to a backpack. Weighing just 344 grams, it is much lighter than most other double-walled bottles. The fully stainless-steel bottle is incredibly durable, robust, and minimalist. The wide body makes it more stable on surfaces, while the reinforced ribs on the exterior make it more resistant to impact. With high-quality vacuum insulation, it keeps your drinks cold for 24 hours or hot for 12 hours. The smooth drinking opening securely covers with the cap to keep it free from dirt, and it is designed to enhance ease of drinking. The Explorer Bottle is BPA-free, 100% leakproof, and fits most backpack side pockets with its 86mm diameter.
