The ILV-20 is a dual chamber, 23-pound buoyancy Infant Life Vest, (FAA/TSO-CI3d defines "infant" as a wearer with a weight less than 35 pounds).* The underarm configuration allows this vest to be used by wearers whose shorter necks prevent use of the standard "Yoke-type" vest.

Note: All of Switlik Parachute Company's "Airline Passenger" Life Vests are also provided for child (35 pounds and above) use.
