“My Mariposa is more comfortable than my Kakwa 40. Same gear load out and everything. Honestly has way too much space in it for me lol. They just recently updated their packs and I can't imagine how they can make it even more comfortable.”

“The sleeping pad you seek is a used Therm-a-Rest Z Lite. It's good to just above freezing temperatures, findable for $20, 10oz before you cut it to size. It's not fun and it's big but warmth per weight and weight per dollar are unbeatable.”
