If your outdoor adventures include "packing it in" few things will make the experience more enjoyable than choosing the right backpack. The primary things to consider are: internal or external frame, capacity and proper fit.

Since their introduction in the late '70's internal frame backpacks have become the choice of most backpackers. Rather than a traditional rigid frame these packs use internal "stays". These removable and flexible pieces can often be formed to fit the contours of your back, providing a snug, comfortable fit. This in turn gives the wearer greater control and balance of the load when traversing rugged terrain. And, since these packs tend to be narrower than external frame packs, they provide free arm movement making them a favorite of climbers and skiers. With their close fit and adjustability these are some of the most comfortable packs available.

External frame backpacks have several advantages over the internal frame models. First of all, they typically cost less than half as much as an internal frame pack making them ideal for the occasional or beginning backpacker. No longer the instruments of torture I recall from my youth, these packs have progressed remarkably in the areas of ergonomics, padding and general comfort. And if you need to move serious weight, these are the packs to use. With their contoured frames transferring most of the weight to your hips you can carry a considerable load over easy to moderate terrain with relative ease. On the down side these packs are not as suitable for rough terrain, bushwacking, skiing, etc. as are the internal frame packs.

When it comes to load capacity the first thing to remember is bigger equals more weight - both the weight of the pack to begin with and how much you put in it. Of course everyone's camping needs are different but pack capacities generally break down as follows:

• 2500 - 3000 cu. in. - day packing or overnight
• 3000 - 5000 cu. in. - 2 to 3 day trips
• 5000 - 6000 cu. in. - up to a week
• 6000 plus cu. in. - expedition or winter capacities. Better be in shape!

Basicly you want the least amount of pack capable of carrying the minimum gear you need to be comfortable for the maximum amount of time you plan to be out. It's amazing how much weight affects distance, ie: the greater the weight, the longer the mile. Plan accordingly.

The importance of proper fit can't be overstated. Few things are as ungainly or uncomfortable as a loaded pack that doesn't fit properly. It will wear you out in no time. To determine the correct size pack for your body you need to know your torso length. To accomplish this have someone measure down your back from the base of your neck (7th vertebrae) to the top of your hip bone. Less than 18 inches equals a "small" pack, 18 to 20 inches equals a "medium" pack and over 20 inches equals a "large" pack. Not too tough...but important.
