Want to use your X2 Trolley with a harness instead of a seat? Alien Flier’s X2 Harness Adaptor makes it possible! Includes Pop n’ Snap* ring and a locking carabineer.

*Alien Flier’s Pop N’ Snap ring is a star feature of our new X2 trolley. It safely locks our one-piece handles into place, allows for quick seat changes and easy trolley removal. This, along with our EZUp Cable System, makes the Alien Flier X2 completely PORTABLE and thoroughly DURABLE!
