Female-specific back length and contoured straps Materials are 100% recycled The hip belt has convenient pockets Adjustable Airspeed carrying system The main material is 100 denier ripstop nylon Flexible side pockets Attachment points for loose straps Two ice axe holders Stow-on-the-Go hiking pole holders Detachable straps for attaching the sleeping pad Chest strap with an emergency whistle on the buckle
