5 of 5 Solid platform June 1, 2021
Reviewer: Redbeard from NH  
Went with my Red Sox hat size. Large was on the money. Don't be a dink and forget to set and tighten your gear, it will feel like its crushing your skull and seem like a non starter, but if you form fit the helmet straps and dial its gonna fit perfectly. Good hook and loop and the NVG bracket is new. Came with NEO cover and extra pads if you are not running inside helmet comms. Good looking out Guys.

3 of 5 SIZE UP!!!!! May 27, 2021
Reviewer: MRAD from Southeast.  
The helmet is clearly well made, and comes with a nice neoprene cover.  My recommendation is to SIZE UP.  Despite having a 23" head (exactly . . . . I've measured about 100 times before I ordered my first TW helmet.  I ended up buying both because I was right on their line between sizes (which is 23"), and it was a hard decision even with both in hand!).  I'm supposed to have a full 1/4" to play with on this Ops Core, but the headband is VERY tight even when the retention system fully loosened.  It's a real shame, because otherwise, this helmet is fantastic.
