OSPREY Duro 1.5

Training, racing, and more. The Duro 1.5 is a svelte hydration companion perfect for training runs, long races, or streamlined days in the mountains. While it may be the smallest volume vest-pack in this series, it will carry you further than you ever imagined.
BUILT FOR SPEED
Vest-pack fit provides bounce-free stability and purpose-built for incredible comfort so you can focus on FKT's and PR's.
HYDRATION INCLUDED
Bottles, reservoirs, and add-on flexibility for short runs, long runs, and everything in between. You decide what you need. Duro/Dyna makes it possible.
EASY GEAR ACCESS
Pockets up front for quick access to fuel and soft flasks, trekking pole storage when you need to use your hands as much as your feet to move forward, and room for rain gear and extra layers.
SIZING OVERVIEW
TORSO SIZING
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.
HARNESS SIZING
Osprey Xenith, Xena, Aether, Ariel, Atmos and Aura packs offer interchangeable shoulder harnesses. Harness sizing usually corresponds to pack size. A properly fit harness should terminate 2" to 3" beneath the armpit when at the proper torso length. The webbing should not touch the side of the body below the padding.
WOMEN'S SPECIFIC
True function and comfort along with style. We have over 20 years of experience designing women's packs.
PACK'S SHAPE
The pack's shape is patterned to be more narrow and with added depth in the right places. This allows greater freedom of movement and increases stabilization by lowering the position of the load to a more optimal center of gravity.
HARNESS
The shoulder harness is designed with thoughtful angle changes and varying padding thickness to create an anatomical fit for a woman's neck, shoulders and chest. This is balanced with optimizing where the tension from the pack's load is carried.
HIPBELT
The hipbelt is designed with thoughtful angle changes and varying padding thickness to create an anatomical fit. The hipbelt is also narrower in height for better comfort so it doesn't dig into the ribs or upper thighs when scrambling or climbing.
MEN'S / UNISEX SIZING
WOMEN'S / KID'S SIZING
HIPBELT SIZING
Osprey Xenith, Xena, Aether, Ariel and Variant series packs offer interchangeable hipbelts. To determine hipbelt size, measure around the hips, at the iliac crest, not the waist. The padded portion should wrap well around the hips, leaving a gap of 3" to 6" between the tips of both hip pads when securely tightened.
