Good tow systems come in small packages. Kokatat Slipstream Tow Line is a full featured tow system but in the smallest package available so it is more comfortable to wear 99.999% of the time (when you are wearing it just in case but not actually towing). It comes with the smallest diameter floating line of any tow system (keeping the bulk minimized), an nylon carabiner instead of metal biner (so it doesn't take a huge float to keep it from sinking), a small line float (thanks to the nylon biner whick keeps the bulk minimized), pull-ball on string for the quick release safety cam-buckle. An internal quick-release on the belt allows you to go from short tow to long tow (letting all the line out; see the red pull-ball at the end of the bag in the photo). The bag opens up like a blanket making it easier to repack the line.

Meets Canadian Coast Guard Regulations as a buoyant heaving line.
