This rearming kit from the Swedish company CM Hammar AB will make any lifejacket with a Hammar A1 lifejacket inflator operational again after inflation. An opener key and an instruction manual (in English, German, French, Swedish, Norwegian, Danish, Finnish, Estonian, Dutch, Italian and Spanish) is also included in the package. The only thing else you'll need is a Co2-cylinder which is sold separately on the previous page.
