Name: SDS - Molle Medical Pack (USGI issue)
Cost: Over $300 retail, but routinely available for $30-75 surplus as they are apparently being replaced (with the same in UCP?)
Capacity/Dimensions: Did not measure. Same height as a 3-day, slightly wider and squarer. I can fit all gear for 3 days of casual living, including: ICS fly and poles, bivy, light sleeping bag, NODs, batteries, food, ammo, goretex, etc.
Pros: Panel loading. Much easier to take advantage of space. Many storage areas: two flaps (flop to side to allow access to inner pack removable by twin SRs each have two mesh pockets; water/radio pouch; map/info pouch with clear cover on lid; small pouches along top and bottom edges close with velcro, take up no room. Some PALS on sides. Pockets provided to fit side pals are good size. QD shoulder straps for ditching. External tiedown on top for oversized items. Compression straps across body of pack.
Cons: Presuming use as an assault pack, not a medpack . . . IV sling snaps in, and is odd and not useful. Remove and store. Velcro closures on storage areas are poor, feels like items will fall out when not all folded and sealed. No waist belt or possibility of one. No water or radio passthru. Zippers are very coarse and can hang up. Storm flap is SDS-style, so backwards; tends to be not covering zippers. No sternum strap as standard (can fit ALICE one though). No PALS on face or interior. No tietown or lashpoints on bottom for oversize gear. Does not fit any framesheet.
