Simpler is often better, and if you prefer going light and moving fast in the woods, mountains and beyond, the Tempest 40 is the pack for you. 40L of capacity is perfect for committing day hikes and lightweight multi-day trips. Ventilated and comfortable, the women's specific BioStretch™ harness and continuous wrap hipbelt combine with a fiberglass frame to create an incredibly stable carry system that hugs your body so you can stay balanced on the trail, ridge or peak. We scratched our heads and updated our AirScape™ backpanel to use less material and glue while making it more breathable to keep you cool on hot days. When uphills turn technical, our Stow-on-the-Go™ trekking pole carry system keeps your hands free for upward movement. Zippered hipbelts, side stretch mesh pockets with dual access, a harness pocket, and top-lid storage provide all the organization you need.Features and Specifications

Sizing and Fitting of your Osprey Pack

Fit is the key to pack performance. Take the time to get it right. Most Osprey packs are available in multiple sizes to fit a range of torso lengths. To find your torso length, have a friend measure your back along the spine (as shown in the picture below) from the level of your iliac crest (the top of your hipbones) to your C7 (the knobby bone at the base of your neck). Use the table below to determine your pack size.
