The carrier system is comparable to the belt system of a backpack. It is individually adjustable to all body sizes and comes equipped with safety reflectors. After adjusting the belts to your body size, the carrier system can be fastened very easily and within a few seconds. Highest carrying comfort is guaranteed. The Swing Handsfree Umbrella and Telescope Handsfree Umbrella can be attached to this carrier system by the clips which come with the umbrellas. Together, with this carrier system, the Swing Handsfree and TeleScope Handsfree are ideal for hikers without a backpack, for mothers with their baby stroller, for nature photographers, and for everyone who stays outside in rain or sun who need to keep both hands free. Material: 100% Synthetic.
