1200g High-Altitude Balloon — Built to Rise

A balloon built to chart new heights, not just birthdays.

This 1200g high-altitude balloon is made from durable neoprene and engineered to climb well beyond where an ordinary party balloon would burst — reaching a burst diameter of up to 8.6 metres (28.3 ft) from a ground inflation span of around 5.5 metres (18 ft). Think of it as your vessel for the thin air above the crow's nest.

Filled with hydrogen, it holds over 58 cubic metres of lifting gas, giving it real capacity for high-altitude projects such as weather tracking, near-space photography rigs, or science experiments that need genuine lift and a real ceiling. A harness and cargo net aren't included, so you'll need to rig your own gear for whatever payload you're sending up.

Hydrogen is flammable, so handle and fill it with proper care and in line with your local regulations — this is a serious piece of kit for a serious voyage, not a casual novelty.
