The reviewer noticed increased pressure points from the Southwest 55L’s thin shoulder-strap padding when loads exceeded 30 pounds. The Southwest 55L uses a roll-top closure that leaves a smooth top panel for sleeping pads or bear canisters. The reviewer found the Southwest 55L’s dual-density hipbelt foam stable and comfortable, effectively transferring pack weight onto the hips.
The reviewer says the Southwest 55L’s curved frame separates it from the back, though airflow is lower than with mesh trampoline designs. Two removable aluminum stays give the Southwest 55L structure and load transfer without traditional load lifters, according to the reviewer.
