Here's my $0.02 the SOL looks like a pretty good edc supliment and I like the idea of the dry bag. If I bought one I'd swap out the fox40 and matches for a mini bic, water purification tabs, baby bottle liners, and a tube of super glue. Between this modified SOL and my normal EDC (compas on watch, BM 551, Fox40 on keycahin, paracord on wrist, and bandana) I think the SOL would be a good compromise between function and size.

shelter (heat sheet, to supplement improvised shelter built with knife and maybe paracord)
water purification and transportation (purification tabs and baby bottle liners)
signalling (fox40 and mirror)
2x compasses
fishing gear
duct tape
First aid (super glue and a bandanna)
