I run a bit on the heavier side, but really beginning to replace everything with ultralight. On my last trip since it was going to be colder and 5 days, I went with a pack which is a Dana K2 that comes in at a hefty 7lbs, add my tent at 3 lbs, this trip I went with my heavier bag at 3lbs, canister at 3lbs, air mattress and pillow 1 at 1 lb, water filter, stove and fuel, 2lbs, puts me at 18 for the basic pack Heavy on clothes, big jacket, fleece pants, socks for everyday, shirts put me at 11lbs for clothes. Miscellaneous stuff(headlamp, first aid kit, and other odds and ends, and of course my chair, adds another 5lbs, food, and we eat really well, is another 5lbs, for total of 40lbs for the late fall 5 day trip. This trip were 8-12 miles a day.
In the summer, for a weekender, I go very light, use a much smaller pack that weighs 2lbs, a lighter cool sleeping bag from the 70's 1.5 lbs, canister 3lbs, same tent at 3lbs, air mattress and pillow 1lb, food 5lbs, odds and ends(filter, stove fuel, headlamp, etc and yes the 8 oz chair comes along
for about 3lbs, and clothes 3 lbs for a total weight 21.5 lbs
Weekender mileage wise run fro a couple of miles to 14-15 miles.
Will look at a lighter canister next , and replace the water filter with new technology and lighter. Owning my own business and getting it off the ground has severely limited the amount of time I have for backppacking anymore, so changing equipment has been a slow process. But it is really starting to take off, so I am hoping next summer/fall I can get out more.
