Black+Blum Stainless Steel Insulated Explorer Flask with 2 Cups

A rugged 1L insulated flask with two stainless steel cups for sharing hot or cold drinks outdoors.

The Black+Blum Explorer Flask Duo is a vacuum-insulated stainless steel flask for sharing a drink together. With a generous 1L capacity, two integrated steel cups, and a practical carry strap, it is a smart option for couples, friends, or families who want to take tea, coffee, soup, or cold drinks on the go.

Made from durable 304 / 18-8 stainless steel, this flask is built for reliable thermal performance. It keeps drinks hot and cold for up to 24 hours, while the 100% leakproof construction helps prevent spills in bags or picnic baskets. With a reinforced structure, steel cap, and easy-pour mechanism. Double-walled cups keep your drink insulated even after pouring.

The two 200ml cups screw neatly onto the top and bottom, so everything stays together in one compact design. The cups also have a wider base for better stability on uneven ground, which is a thoughtful detail for hiking, festivals, and stop-offs along the way. Fill it with coffee for an early morning walk, hot chocolate for a family day out, or soup for a cold-weather hike.
