How to Measure:: For best results, have someone take the measurement for you.
Torso:: Start at the iliac crest (the top of your hipbone that you can feel like a shelf on the side of your body). From this level on your spine, measure to the C7 vertebrae, the knobby bone at the base of your neck when you put your head down. Make sure to keep your back straight while having the measurement taken.
Hip:: Measure around your hips, at your iliac crest, not your waist.

Siskin 8L Backpack

The Osprey Packs Siskin 8L Backpack offers just enough room for your water and a few absolute essentials when you're hitting the trails for a day of mountain biking or hiking. The included 2.5L reservoir keeps you hydrated while the u-zip main compartment opens wide so you can stuff in a spare tube, repair tools, snacks, and an extra layer. The front of the pack has a LidLock attachment point for your standard size helmet, or, if you've got your full face helmet, the side compression straps expand so it fits comfortably. The Siskin's mesh covered backpanel and supportive shoulder straps make carrying the pack comfortable and easy so you can focus on the trail ahead.

Great for MTB but also great for Skiing

I originally bought this for MTB and I think it was a little late for the season but then tried it out skiing and couldn't be happier for those longer days. Have used so much and have no complaints!

All Day Adventures

Familiarity: I've put it through the wringer

I love this pack. Its light, comfortable, and carries just what I need. You dont need much for a mountain biking day and this pack is perfect for water, food, and tools. This is my go to pack for longer days in the desert. I would highly recommend this or even the Salida is a great bike pack for longer days on wheels!
