Okay, maybe not ultra light, but considerably lighter. I typically carry a lot of heavy, and bulky gear. When heading out for 3 days, I'm packed to about 45lbs in a Kelty Tioga 5500(90L). On the other hand my day kits are bare bones. I need to hit middle ground. So now I want to put together a kit based off of my Watershed Animas pack. https://www.drybags.com/product/animas/ I've had this pack for about a year and have never used it. I packed it full of towels and other junk the other day and it's quite comfortable for a frameless pack. I'm thinking if i can keep my weight around 15-20lbs before water it'll work out fine. It's a 40L pack, so can hold a decent amount of gear. I'm also trying to only use gear that's fairly quick into use as well. No wood stoves and such. Gear list so far: Animas pack (37.6oz) 6x10 Etowah tarp (18oz) Thermarest Ridgerest pad (14oz) Jungle blanket (25oz) Sea to Summit pillow (2.8oz) MSR Pocket Rocket 2 (2.6oz) Toaks 550 pot (3.5oz) Titanium chop sticks (0.4oz) So as of right now, I'm at 6.5lbs. I'll update this as I go. I might actually like lightweight business ETA: This is a 3 season kit.
