Having the correct fit goes a long way in making your trip more comfortable and ultimately more enjoyable.
Some backpacks are available in multiple sizes, from extra small to large, which fit a range of torso lengths. These ranges vary by manufacturer and by gender. Check the product specifications tab for your sizing details of the brand you intend on buying.
The pack's weight should be distributed to your waist (1) and NOT on your shoulders.
CAPACITY GUIDE:
The size pack you'll need is tied to the length of your trip and how much weight and bulk you want to carry.
Weekend: (1-3 Nights: 30- 50Lt)
Multiday: (3-5 Nights: 50-80Lt)
Extended: (5+ Nights: 70+ Lt)

TORSO LENGTH:
