APCO Mayday Reserve Parachutes
Apco Aviation started manufacturing the Mayday reserve parachute in 1977, and since then put over 30 000 pieces into service in the Paragliding and Hang Gliding markets. The Mayday has hundreds of life saving deployments to its name, from beginners to world champions ( Read letters from saved pilots).
The Mayday Square follows in the proud tradition of the Mayday Range, and is built to the same exacting standards that has made the Mayday range the benchmark of all reserve parachute systems.

Important Sizing Notice
Please make sure that the reserve size you select is compatible with your harness reserve pocket/container.
We are happy to assist with reserve size selection, but it remains the buyer’s responsibility to confirm compatibility with their specific harness.
FlyMachine SA cannot accept returns, refunds, or exchanges if the reserve does not fit your harness pocket after purchase, and cannot be held responsible for incorrect size selection or harness compatibility issues.
Please check your harness manual or contact us before ordering if you are unsure.
Packed Size vs. Volume:
The volume is measured by water displacement, and represents the smallest recommended packed volume, or the volume of the smallest recommended container to be used for the reserve. The specified volume is therefore far lower than the calculated volume that would be derived from the specified measurements.
The Packed Size measurement represents the measurements of the factory packed, but not compressed reserve, ie. the max dimension for each axis, and in its specified deployment bag, as shipped from apco.
The weight may vary by up to ±3%.
