This is the link to an equipment list I've prepared for a hike in the Wind River Mountains the last two weeks of August this year.
I'm 63 years old and in good shape.

The issues I'm concerned with are:
Pack: The Osprey 85L vs. Hyperlight Ice Pack 4000. I already own the Osprey 85L pack which is 3 pounds heavier than the Hyperlight Ice Pack 4000. It is however, extremely comfortable. With the pack loaded correctly, I'm barely aware of the load, which I attribute to the luxurious suspension. ( which weighs extra). Can the Ice Pack be as comfortable? Last year I did a shorter version of this trip with a GoLite Jam 2 and a 25 lbs load. The pack is light, but it was painful compared to the Osprey. I don't want to spend another 350 dollars to save three pounds but end up in agony.
Food: Most of the hike is above 9500 ft. and in the past when I get to that altitude, I have not much appetite. The rule of thumb '2 lbs per day', is more than twice what I feel comfortable with. Glorious trout live in these mountain lakes that I count on catching, and I have a bit of a Winter battery pack formed around my waist, so I will hardly be lacking for food.
Tent: The Big Agnes 2 is a bit heavy compared to ultralights, but its self standing and fast to set up. Often, stakes won't go into rock. Mosquitoes are still abundant this time of year. The extra space is necessary for a pack this big.
GPS plus batteries: Too much weight. I feel challenged to use just the compass and topo maps.
Bear Spray: Skip it. The chances are remote, and any way at my age, an epitaph that reads: 'Et by Grizzly' is better than a nursing home.
Camera: The camera weight is extravagant, but the GX7 is converted to infrared which makes incredible photos of the mountains, from which I paint oil landscapes; the primary excuse to make this hike.
Clothes: I've found that in The Winds, I wear the rain gear pretty much all the time – it rains quite a bit, and the mosquitos can't bite through it.
Nothing on the list is written in stone; any helpful comments or suggestions are welcomed!
