Mattresses and pillows oh my…I recently purchased a pack liner and so I wanted to open up my pack and clean things up a bit before my next hike; and it’s also s much a mental exercise than anything else. I was also surprised because I found extra pillows in here.From left to right…giant ziplock easily replaced with a waterproof compression sack or pack liner. Ziplocks are cheap and replaced at any grocery. Pack liners too.Borah net bivy with ridge zipper; it will be placed in the liner/bag without a stuff sack6x9 black tarp in a blue stuff sack. I will certainly leave the sack behind because I need quick deploy and I do not mind if the pack is wet.Sleeping bag liner. This one is for winter and frankly never worked. I was just meant to add a little comfort (more below)polycryo groundsheet. Not really necessary because I consider the bivy generally disposable, however, condensation from the ground means it can collect sand or other bits and if the bivy is to be packed in the liner it should be dry.small black synthetic pilow and medium brown inflatable from Snugpak. This was a surprise because I remember making the purchase just not putting it in my pack. The combination gave me some comfort and choices.The mattress is a regular length Klymit ultra light. It’s loft is not as high as the other but it’s longer and just as comfortable. Different fill valve too. So I’m not a fan of the sleeping bag liner and I like the blanket … the weight is close to the same but the volume is a bit different but it should work. The blanket is also better if it gets wet. Where the liner is a fail when when.I plan to carry an umbrella in order to block the rain from the head end of the tarp, however, ponchos and rain jackets have many functions. The yellow poncho is light and can double as a tarp. The black poncho has sleeves and because it’s black it can keep you warmer and it should dry faster. For the time-being I think warmer and dry faster are better.
