he Edge range is our value range, these life jackets are all 150N but in order to reduce cost and weight they are self coved (the bladder has no cover). This makes them very low profile and light weight which makes them ideal for infrequent users or those for who every gram counts. The Edge is available in either Red or Black, with either harness or without and in either manual or automatic inflation. There is also an oral inflate version available in red.
