If you're considering the RAID, I would like to bring up another contender -
http://www.rstacticalgear.com/pd_sap.cfm
Thats a Tactical Assault System/Patriot PErformance Small Assault Pack.
They run 150.00 are built better (IMO) than the RAID and offers several advantages.
INCLUDED -
twin 6061 AL stays for structure, External pocket layout ala 3 day packs, internal Map/MPH pocket with PALS weebing, PALS around the Periphery of the pack body, the dimension is slightly shorter than the RAID, but I see that as a plus.
And to boot they ARE available, I use one in grey for my work bag and have another on the way in for a review cross comparison between Kifaru, Eagle, PPM and BHI
Stay tuned.
