The new women's specific Eja 48 splits the difference between the 58's thru-hiking prowess and the 38's ninja-like streamlined nature. It works great for weekend trips and depending on your packing style can go way further. The incredibly comfortable Exoform harness and AirSpeed ventilated suspension combine with trail-friendly features like Stow-on-the-Go trekking pole carry to make every backpacking trip as comfortable and enjoyable as possible.
Many Osprey packs are available in multiple sizes to fit a range of torso lengths. To determine your torso measurement, please see diagram below:
This measurement starts at the iliac crest, which is the top of your hipbone on the side of your body that acts like a shelf. From this point, measure to the C7 vertebra, the knobby bone at the base of your neck when you put your head down. Reference the torso length below to match the correct pack size.
