Lightweight, streamlined climbing and mountaineering pack for long days in the mountains. The 38 adds ski carry, helmet carry, hipbelt gear loops and removable top lid.
Your torso size is the most important measurement and is what determines your pack size. Many Osprey packs are available in multiple sizes to fit a range of torso lengths. To determine your torso measurement at home have a friend measure the length of your back along the spine. Start at the iliac crest which is an imaginary line drawn across the top of your hip bones. From this level, measure to the C7 vertebrae, the knobby bone at the base of your neck that protrudes when you put your head down. Make sure to keep your back straight while your friend makes the measurement. If you are between sizes, it's best to come into our store, where you can try on both sizes.

The Right Shoe Project
Shoes are made in many factories around the world and even models within the same brand can be quite different. To assist our customers in choosing the right size, we measure every shoe we receive. All this information is compiled so you can simply enter the length of your foot in centimetres, choose your preferred fit, and our calculator will recommend a size for you! Then, as you browse the website across various brands and models of shoes, we will provide a recommendation of your sizing in each model.
Still not sure? If you're in Brisbane, feel free to come in to our store in Milton for a fitting. Otherwise, you can contact our team for assistance and advice.
If you would like to contribute to helping other customers please contact us with your shoe size, foot length and how well your shoes fit.
