Had a Hex, now have a Recon. When I first tried the Recon it felt more on top of my head whereas in the Hex, my head felt more ‘in it’. Felt a bit weird at first but soon got used to it and now the Recon feels absolutely fine, though maybe the Hex was a tiny amount more comfortable.
Sizewise, my head was in between sizes so went for the large/XL which was way too big so returned it for a small/medium which was much better. Sizing may be a small issue so I’d try before you but if you can.
Would recommend the 661 if only coz they look ace!
