The Carbon/Kevlar-made sled is designed to be easy to load and unload due to its wide and flat base. The design of the front part of the sled is very smooth both vertically and horizontally. On the bottom of the sled, there's two skids made of sintered Polyethylene (UHMWPE), same as on XC skis. The shaft is constructed in one piece; there are no connections or attachments that can be broken. Easy to use, and not requiring any maintenance.
