    Reality… walking with a huge rack of horns on your upper pack is a GREAT way to get shot by a hunter, like even better then wearing brown, it is in fact the best way to get shot accidentally by a hunter, especially while crossing on open field.

  2. When is the new frame from shot show releasing?

  3. I got this one with pair of batwings, and this is awesome carrier for various purposes. You can hike for day with batwings, adding duffle makes enough to camp couple of days. When emergency situation, it can carry wounded person, work as stretcher (only have tried 120lb woman). But I’m curious, is it ok to load such a weighty object on the bent part for long time?

  4. When will the new bags be revealed that are mentioned at shot show?

  5. wtf. why they lead out w saying Mainframe n basically also sayin it’s a Mod sys?! which is it?! i just researched newest packs n read Modular was best – now im
    confused. sorry if its me but what gives lol/smh
