The AP Valves 25kg Lift Bag is manufactured from bright red heavy-duty polyurethane coated nylon with extremely durable high-frequency welded seams.

You have three choices of models:

• The Open-ended version which is easily filled from your second stage but the gas is free to escape should the opening become the highest point.
• The Open-ended version with an over-pressure / dump valve features a pull-cord dump / over-pressurisation valve that adds a level of control over the lift back buoyancy.
• The Self-sealing version features a unique duckbill baffle that seals shut on inflation to prevent air spillage at the surface. It is also fitted with an over-pressurisation dump valve to prevent the lift bag from rupturing during ascent.
