This is an unusual but important topic, especially for backpacking. Keep your pack light for safety. In the mountains falling is one of our biggest safety risks. Loose footing, steep hillsides, and adverse weather, including snow and ice, all increase the risk.
Don’t be fatigued and off-balance. Keep light and nimble. It’s not just your enjoyment at risk. Heavy packs are unnatural and can throw you off balance in the worst of times. I know. A long time ago, my friends called me the Winnebago backpacker.
Spend some time to lighten your load. Lay all your gear out and work to reduce weight one step at a time. I do this in the winter. It primes me for the upcoming hiking season.
Essential to your light pack is the 10-pound core. Make it your goal to have your tent, pack, sleeping bag, and sleeping mat under 10 pounds unless you are snow camping.
