Is she going to be using these in the rain? Pluses for Ortleib are absolute waterproofing, both now and for years/decades to come. On/off the racks is so easy she never needs to open them in the rain. The yellow ones have another plus. They just might get noticed by an otherwise oblivious driver. (And those have been observed around college campuses.) Ortleibs are also up to college life abuse. Falling off the rack while going downhill, loaded and heavy, simply doesn't phase them. (Mine, at 14 and 24 years old have done that a few times. Skidded some nice long distances. Only repairs I have done are once, a routine raft repair after I stuck a very sharp kitchen knife through it and new hardware about every 8 years. (Used to be $35 a pair for the hooks.)
