Love it. much cooler than anything i've tried.
Freaking love this! when i first put it on i thought it was going to be just as hot as everything else, but the two gray vented sections really let the air move through, even with a jersey over it. 100x cooler than my leatt 5.5 body protector. elbows stay in place! can't say that about the leatt 5.5. easier to take off than the leatt as well. took some dead, downed trees to the chest like a joust that i was sure would have at least tore the fabric and perhaps even the foam, but there was barely even a mark. i'm 5'11", 230 lbs, 45" chest. l fits great though slightly on the long side. i've not seen anyone else answer this question, but it worked great with my leatt 4.5 adventure neck brace after removing the top-center pads front and rear, which aren't needed anyways since the leatt covers that area.
