The most innovative and compact carp retention system ever, using the proven Nash Carp Care sling design with high water exchange and a net suitable for protecting mucus, now featuring inflatable buoyancy tubes that support a carp in an upright position, but when deflated allow the sling to fold into its small pocket. The carry bag with taped seams is equipped with a one-way valve, allowing it to connect to the inflatable tubes, and the rolled-down neck acts as a pump. Both tubes can be inflated in seconds without manual blowing. Innovative inflatable tubes support carps in an upright position while also providing compact packing. The carry case also functions as an inflation pump. Webbing carry handles with a self-centering metal loop also serve as a weighing harness. Fixing cord with 3/8 BSF threading for securing with pegs and poles.
