rakesh patelwrote a review of Troy Lee Designs A-1 MIPS Helmet on August 11, 2016
Familiarity: I returned this product before using it
I bought a M/L, though I usually fit into smaller helmets, like the S Smith Forefront. The helmet is pretty bulky on the exterior. The interior fit around my head well, just felt the exterior was too large. Uncertain if MIPs adds to bulk.
