When the hike is steep and long, experienced hikers will look to shave weight. A key target: your choice of shelter. Some will go minimalist with just a tarp or rain fly but I always prefer the tent for its comfort, bug, snake resistence, and total wind and weather proofness. So for these hikes a very light tent is in order. All manufacturers lowball their tent weights; I find them to be about 1 lb underrated. Therefore a quality 2-person tent often weighs about 6.5 lbs. The REI Quarterdome T2 Plus (extended version of the regular Quarterdome) breaks those ranks with a 5 lb tent (about 5 lbs 5 oz after stake, footprint, guyline upgrades that I do). For a tent providing 35 square feet of livability and 15 square feet of vesitbule storage area, that is an achievement (the T3 Plus will have 47+15 sq ft but is heavier).
