Want to use your X3 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 X3 trolley. It safely locks our one-piece handles into place, allows for quick seat changes and easy trolley removal.
