The FTC Matriosac 3 is a throwline bag set is composed of two round bags, that fit into each other and fold to a compact size. Two sets for throwing can be stored, i.e. 2 throwlines and 4 throwbags. The inner pocket is oriented so that when the bag is carried with the side handle, the gear stays nicely put. It is also equipped with a large pocket under the large bag, for extra gear (cambium saver, throwbags, carabiners etc.).

Folding the bag holds the throwline flat at the bottom and four straps with quick-release buckles hold the set folded together.

Once it is open, the FTC Matriosac 3 is very stable, held on the ground by the bags and accessories held in the bottom pockets that act as ballast. Its round profile means a lesser wind surface area. The bottom is reinforced and waterproof – it is therefore stronger and offers the gear a better protection against ground moisture.
