I’ve enjoyed reading Jim’s pack weight poll. I haven’t done the math, but I suspect that the average pack weight from that thread is 7-8 lbs. So here’s my question. At what point does reducing pack weight stop being about practical weight reduction and start becoming an exercise in gram counting for gram counting’s sake.
Don’t get me wrong. I’m in awe of people who take multi-day backpacking trips with a 5 lb (or lighter) pack. If you are reducing pack weight (and the amount of gear that you carry) to see how light you can go or to test your limits, that’s an admirable goal, but from a physiological standpoint, is there a difference between the amount of energy that you expend carrying an 8 lb pack vs. a 5 lb pack?
Dan McHale, on his letter page brings up an excellent point. If you calculate the weight of your body, clothing and pack weight including consumables, the percentage difference of a few pounds is much less that 1%. Can your body really feel that at the end of a day?
