I’ve a Volt, considered the charge but the actual size of the packs is pretty similar. If I want less stuff I don’t take a pack at all and use jersey pockets. With all the compression straps done up it’s pretty small inside.
Only criticism I have is the tool organizer bit it right at the bottom, I’d much prefer it where the MP3 player pocket is at the top. Solved it by making a tool roll that’s easy enough to grab and pull out from under stuff.
Helmet strap isn’t really stable enough to hold a heavy FF off road. Never noticed it digging in, but it just swings side to side.
