The Black & Blum Explorer Flask Duo isn't just another thermos - it's your companion for serious adventures where temperature matters.

This 1-litre powerhouse keeps drinks piping hot or ice-cold for a full 24 hours, whether you're summiting peaks, hitting the slopes, or camping under the stars.

What sets it apart? Two double-walled stainless steel cups that actually work. No flimsy plastic linings or wobbly bases—these 200ml cups are engineered for real outdoor use with wide, stable bottoms that won't tip on rough terrain.

The ribbed body construction takes whatever nature throws at it, while the easy-pour mechanism prevents spills when your hands are cold or gloved.

Built for sharing adventures:

• 24-hour temperature retention (hot or cold)
• Two premium double-walled steel cups included
• 100% leak-proof vacuum insulation
• Wide-base cups stay stable on rough ground
• Reinforced ribbed body construction
• Removable nylon carry strap
• Easy-pour mechanism reduces spills
• Completely plastic-free drinking experience
• Dishwasher safe (remove strap first)

Whether you're sharing morning coffee on a mountain summit or warming soup after a long hike, this flask delivers the performance and durability that real adventures demand.

Stop settling for lukewarm disappointment, and invest in gear that keeps pace with your biggest expeditions.

Perfect for solo explorers or adventure partnerships where great gear gets shared.
