Based on a tried and true military/sport "free bag" design, the SkyAngle Deployment FreeBagTM attaches directly to the nose cone with a 1" tubular nylon (4,000 psi) tether. All stress points are reinforced with Kevlar® thread. Ingenious in its simplicity and ease-of use, this deployment sleeve completely envelopes the parachute in fireproof Aramid® fabric while insuring a reliable, orderly deployment! Complete illustrated instructions are included. SkyAngle Deployment FreeBagsTM are engineered with high quality materials, impeccable craftsmanship, and are very affordable. They are available in four sizes, three of which are tailored to fit our SkyAngle CERT-3 main chutes. (They work great with other brands as well.)
