It's not a bad year round list Simon, but you should add everything carried, including w/proof jacket, w/proof trousers, insulating top, spare clothing etc. The only things to be left out of a base-weight is consumables. Food, liquid, fuel etc. You could cut it by 2/3 if you carry a seasonal pack. I don't carry more than a 2-3kg base weight in Summer. I'm no spring chicken either by the way!
Fair point Mike, add either 327g or 920g. That's either 7056g or 7649g, depending on the time of year. Of course, in summer I would only take one hat and no gloves. So that's 6907g, or 6717 if you don't include the fuel. ( Or 8115g for winter, when I take the Paramo and the down jacket. But then I'd have quite a bit of other stuff as well. ) That's the lot, bar consumables. I don't carry spare socks, waterproof trousers, other spare clothing etc. I have included fuel.
Shirley, if you wear Paramo you don't get wet.  Michael, I was 50 last week.  I also have a serious medical condition. It kept me off the hills for 25 years, but has improved to the extent that I restarted backpacking 2 years ago. Mike I would be very interested in a 3kg summer gear list. Would that last for 3 days, 2 nights ? I'm getting horribly reminded of why I stopped posting on OM. So if I suddenly stop replying, apologies. In that event I may start a similar thread on Scottish Hills. |
