Invision
A firm fit- better foam maybe?
Small- may expose your chin if you have a big head, but they feel like a small profile
Very difficult to rmove and replce lenses
The lenses fog more than most I have used, so if you sweat, look out
JT Flex7 Ize
Fold up nice and small in the gear bag
The bottom gets deformed easily when you fold it up in the gear bag
Good anti-fog, but delicate
Large coverage but not a large profile
Crappy foam- they feel wiggly on my face
Profiler
Fold up almost as small as JT, but not quite
Easiest lens to change out of these three
Best field of vision out of these
Best anti-fog treatment, for durability and effectiveness
The rubber can tear after long use
Fill sometimes sprays inside the goggle, which is scary but mostly harmless
Slightly bigger profile than the others
Excellent foam, but not as nice as the Invision
