As reference, this fits similarly to the Patagonia R1 full zip and retro-x vest where I'm a medium (5'10, 165 lbs, 32 waist).
If the vest is layered over the R1, the R1 hangs about 1 inch longer in the back. So the tech vest runs short and will have a very slimming look, but nothing I would complain about.
I initially ordered a L but it was a bit too baggy, particularly around the stomach.
This fits close to the body so I can't put a thick hoody under it, but this layers very well over a t-shirt and light midlayer, and under a ski jacket.
If you have a gut, then I'd order a size up, but otherwise, get your usual size.
Quality is great as expected from MHW.
Smith said it's fully detachable via velcro, but with the help of BC's live chat, I found that one mine (cyan team) the plastic arm of the BOA over the temples are detachable..just give it a tug and the arms will pop off and you can slip off the earpads completely.
Thanks, it didn't come with a tool but I have a torx screwdriver that fit and undid the screw. I took off the ratchet knob, but even if I unwire the BOA, doesn't look like it can come apart enough to completely detach the ear pads. I'm going to shoot an email to Smith in the meantime...
I can unclip the earpads, but how do I get it completely detached from the helmet? The boa plastic straps are woven into the pads so they won't come completely off unless the boa system can come separated too. Is this even possible?
