Some colours make a statement. Black simply means business. The Nayasa Vacuum Flask Hangout in Black is a 600ml double-wall 304-grade stainless steel flask that pairs a clean, no-fuss aesthetic with dependable vacuum insulation — keeping hot drinks warm and cold drinks cool for hours on end. Whether you are hiking, commuting, or grinding through a long office day, the Black Hangout 700 is the flask that gets out of your way and does its job.
The Black Hangout has earned strong reviews from daily users who value its sleek look, its ability to hold temperature through demanding use, and a build quality that takes knocks without complaint. It fits in bags, backpacks, and car cup holders with equal ease, making it a genuinely versatile companion for any kind of day.
The Black Hangout wears an understated, sleek black exterior that works across every context — boardroom to trail, office desk to gym bag. It is the colour that matches everything and draws its own quiet attention, never looking out of place wherever the day takes you.
Both the inner and outer walls are food-grade 304 stainless steel — the same grade used in professional kitchens and trusted for long-term contact with beverages of all kinds. The construction is corrosion-resistant, rust-free, and flavour-neutral, ensuring every sip tastes clean and uncontaminated.
The evacuated air cavity between the double steel walls dramatically slows heat exchange, keeping hot beverages warm and cold drinks refreshingly cool well into the day. Customers who use the Black Hangout on hikes and long commutes confirm it delivers reliable temperature performance across demanding real-world use.
The Hangout 700's screw lid seals firmly against leaks, making it safe to carry in a bag alongside books, electronics, or clothing. Customers have tested it on hikes and at work — no spills, no dampness, no surprises. A flask that earns trust on day one.
The all-stainless construction is inherently resistant to the corrosive effects of everyday beverages — acidic fruit juices, lemon water, hot tea, and black coffee included. The Black Hangout is built to be used hard, washed clean, and used again without any degradation in performance or safety.
The slim profile of the Hangout 700 fits snugly into standard backpack side pockets, gym bag compartments, and car cup holders. At 600ml it hits the sweet spot for all-day carry — generous enough for real hydration needs, compact enough to take anywhere.
The drinking capacity is 600ml — sized for comfortable all-day carry whether you are at a desk, on a hike, or heading to the gym.
