Here is my current version of the Hellcat Pack; but with a different look;
Based somewhat on this blog’s instructions….however, significantly different sleep system used. http://libertytreeblogs.blogspot.com/2011/04/building-hellcat-hybrid-ruck-from-us.html
I currently am using USGI ALICE straps and belt pad on this particular version, but I have a MOLLE belt on the other pack, along with longer ALICE padded straps (Similar to Tactical Tailor’s Super Straps) ; May modify my MOLLE shoulder straps to use ALICE style Quick release buckles if I cannot find another MOLLE Quick Release tab and strap The pack currently used, is a Medium LC in standard green, and instead of a MOLLE MSS Sleep System carrier, I used a M1967 sleeping bag carrier to hold my compression bag that holds my underquilt for the hammock; and USGI ALICE pouches for carriage of water and foods. Inside the pack; I have 2 days of clothes, extra socks and underwear, and because of the relatively cold weather, a set of Polypros long johns underwear, acrylic fleece sweater and USGI Extreme Cold Weather Parka with liner and hood. In the compression sack on the bottom, is my Underquilt wrapped in an USGI poncho.
earlier version of the Hellcat pack; 4x MOLLE first aid pouches up top, two SAW ammo pouches on lower sides, shows the MOLLE kidney belt lashed to frameview from rear, long ALICE padded straps, MOLLE kidney belt, behind the straps, Spec Ops HUMP hydration bladder and a 2-man nylon tent, folded into a square and lashed to the frame along with its poles and stakes.
