The SisterPack by APEX gives users the ability to freely modify other pack systems made with 1" webbing and hardware. Evolve and adapt your pack system as needed to get the most out of your gear.
The SisterPack works perfectly with all packs made by APEX. Add some CarryAll Pouches to your configuration and you will have a pack system ready to handle everything you throw into it.
To attach, use the top side G-Hooks to capture a loop on both the top sides of your main pack, then utilize the bottom 1" hardware to attach to the bottom of your main pack.
***special hardware may be needed to attach the SisterPack to your system
