The FastBack 4.0 is a 3-liter hydration pack that fits ICE mesh-seat trikes. Features include dual tubing ports, full-zip side opening for easy bladder removal, oversize capacity, zippered tool pocket, tube holder and rear light mount. It can be used with the optional FastBack Clip-on Pump Pack and the Center Velcro Pad allows attachment of the optional tool pouch. The top-flap design works with headrests. Two adjustable bottom straps are included, for attachment versatility; one encircles the seat, the other uses the frame as an anchor point.
