Anything over 40lbs is getting excessive (including water) and begins to slow me down. 30lbs is much better and 25lbs is even better, but I would have ditch the full sized down pillow and the in 2 man tent stereo entertainment system, the full sized 8x42 Barksa Binos (great for star gazing during the evening), the umbrella solar powered fan cooling system, the fishing rod and reel, the solar shower and the collapsible kitchen sink etc.
