Here are the major changes in the new design:
1. Added stretchy binding on the edges of the fleece shoulder
2. Removed binding on the shoulder straps, helping them slide more easily through the buckles
3. Seat back is approx 1-1.5 inch taller
4. Waist belt webbing is approx 2 inches longer
5. The construction of the seat is now three vertical panels, versus three horizontal pieces.
Other quality details that aren't visible include interior reinforcement for the leg openings, and an extra structural layer under the center print
panel. Lining is plush quilted microfiber (vs. fleece on the classic version).
