WHAT SIZE BACKPACK DO I NEED? Pack Size Torso Length Extra small Up to 15"+ Small 16" to 17"+ Medium/Regular 18" to 19"+ Large/Tall 20"+ (These are general figures. Torso-length ranges can vary slightly by brand.) HERE'S HOW TO MEASURE YOUR TORSO 1. Have a friend locate your C7 vertebra, the most prominent bony bump on the back of your neck when you tilt your head forward. 2. Put your hands on the top edge of your hipbones with your thumbs reaching behind you. Imagine a line running across your low back between your thumbs. 3. Using a flexible measuring tape, your friend should start at the C7 vertebra and measure down your spine to the point where the tape crosses the imaginary line between your thumbs. This distance is your torso length. х HOW REI DETERMINES PAČK VOLUME REI's test team uses a standardized test method, known as the ASTM F2153, to calculate the volume of our REI-brand backpacks. The tester fills the packs-including all the pockets-with gumball-sized plastic balls. The balls are then poured out into a measuring cylinder calibrated to measure liters. Extended Capacity? Many packs are designed with features to increase the carrying capacity beyond the normal capacity. This is also measured at REI, and listed as the Extended Capacity. Prefer cubic inch measurements? To convert liters to cubic inches multiply by 61. THE OLD GAME OF "GUESS THE NUMBER OF JELLY BEANS IN THE JAR" So how many of those 20mm balls would fill a 4,000 in pack? (If you said 15,384, you're correct!) AND NOW FOR THE REALLY SCIENTIFIC PART: How many of the following would fill a 4,000 in³ pack? ITEM NUMBER APPROX. VOLUME, EACH Bacon slices: 1.3 in 4 in 9 in 26.6 in 33.5 in 3,076 iPhones: 1,000 Clif Bars: 444 Hiking socks, rolled pairs: 150 Apples, medium: 119 Wall phones, rotary-dial: 16 250 in Cats, cooperative: Actual results may vary HOW DO I LOAD MY PACK? воттом Sleeping bag and things you'll need only at night (except for your flashlight or headlamp). DISTRIBUTING PACK WEIGHT MIDDLE Heaviest items such as food, hydration system, stove and cook set. They should be close to the spine for good support. Stuff softer, lightweight items around these, such as tent fly and extra HEAVY clothes. MEDIUM TOP LIGHTWEIGHT Lighter-weight items like clothing in a stuff sack and essentials that you'll need easy access to. OUTER POCKETS Snacks, map & compass, sunglasses, toilet paper and trowel, headlamp, sunscreen, first aid and other items you'll need to get to. STUFF POCKET You can stash hat, gloves and an extra layer in the stuff pocket if your pack has one. Some packs have convenient hipbelt pockets for a snack, lip balm, or moleskin, OUTER STRAPS Secure sleeping pad, trekking poles and tent poles with the bottom straps and side straps. Use the daisy chain and lash points for other items like crampons. HOW DO I ADJUST THE FIT OF MY BACKPACK? WHAT TO TAKE THE TEN ESSENTIAL "SYSTEMS" 1. Navigation (map and compass) 2.
