The standard A1 and the new MIPS-equipped model look the same from the outside, but the new helmet's yellow MIPS webbing (on right) is visible when it's flipped over.
TLD Updates the A1
Troy Lee Designs have updated their popular A1 all-mountain helmet, although this iteration won't hit the shelves with just fresh colours and new graphics. The latest version now includes MIPS, a technology still relatively new to mountain bike helmets, but one that's gaining popularity quickly. All other features of the current A1 remain unchanged, including its shape, multi-directional adjustable harness, the one-piece removable liner, and certification for CPSC 1203, CE EN 1078 and AS NZ 2063: 2008 standards.

MIPS - which is the acronym for Multi-directional Impact Protection System - is gaining steam largely thanks to the extra protection it claims to offer against rotational forces on the brain when a rider hits the dirt. This technology allows the helmet to slide relative to the head, removing some of the forces on the brain during a spill. The system is clearly visible on the inside of the updated A1 (note the yellow webbing in the above photo) and despite the addition of this to the classic TLD half lid, the outer shell is the same size and has not changed in shape.
If the loud colours or styles of the $215 USD MIPS-equipped A1 Vertigo aren’t for you, there is a gloss-on-matte black Drone version available with MIPS that retails for $189 USD.
