Our Ultralite models take the lightening process to the limits
of extended durability with lighter fabrics and minimalist design. By incorporating internal
dividers on the larger models, we can use simpler and lighter frame
systems while maintaining our superb back shape. Our Ultralite models
achieve weight to volume ratios of up to 1 kg/40L.
Using one of our packs is the first step in lightening up, but
the pack is only a proportion of the load you carry. In order to
achieve really light loads, each essential item will need to be
chosen for the highest performance/weight ratio. If it is heavy
don’t buy it. Buy the lightest. Ultralite kit for a week’s
hiking can be 5 to 10 kgs lighter than standard equipment. This
makes a huge difference to your enjoyment. Travel farther and more
easily by travelling lighter. And when lightening up, don't forget your footwear. The latest research shows a kilo on the feet is equilavent to 6.5 on the back!
The following website will help you find and evaluate ultralite equipment:
OPTIMUM EFFICENCY = LEAST EFFORT
A Bodypack would weigh a little more than a backpack if it were made of the same materials because there are three separate load-carrying compartments rather than one. How do we decide which one is the most efficient? (i.e. requires the least energy to carry a given weight). Let's take some examples.
1. If the Bodypack and the backpack were the same weight, the Bodypack would always be the most efficient, requiring the least energy to carry.
2. If two backpacks are the same weight and you add Balance Pockets to one, then the one with Balance Pockets will use less energy if the load (including the pack) is over 3 kg. With heavier loads, this energy reduction is magnified.
3. Imagine a pack that is 1 kg lighter than our large Ultralite models because it does not have a frame, an effective hipbelt, Balance Pockets or a waterproof-liner. Sports scientist Ray Lloyd concluded from his research that the energy saving posture of our a partially counterbalanced load Bodypacks would make up for 1 kg extra pack weight with loads over 7 kg.
With a fully counterbalanced body-centered load, we may see similar efficencies to African women carrying head supported loads on level ground - carrying 20% of their body weight with no extra energy consumption. However research on body-centered load carrying has yet to be done. Preffosor Stephen Legg is keen to do the research, but we need substantial funds for a conclusive study.
LESS ENERGY = MORE DISTANCE
The graph above shows the relationship between weight carried,
distance covered and the center of gravity of the load (comparing a backpack with a Bodypack containing a partially countered load).
weight alone will not achieve the minimum effort, maximum distance
load carrying. It is the combination of minimum weight and a load
balanced in front and behind which is necessary to achieve the greatest distance with the least effort.
NATURAL BALANCE + LIGHT LOAD =
MAXIMUM COMFORT & EFFICIENCY=
FARTHEST DISTANCE WITH LEAST EFFORT
