5. REI Co-op Flash 45
Aside from being extremely affordable, light and comfortable, men and women both liked the REI Co-op Flash 45 but for women, it has specific designs ideal for the woman body. The backpack has a canted hip belt that wraps perfect around the pelvis and has boomerang shaped should straps, perfect to give space for breasts. The backpack a simple layout where it has a single compartment lid, two mesh side pockets and no interior pockets. Although, the
compression is above average for a weekend trip.
