https://www.amazon.com/dp/B08H5J5QWJ?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_2&th=1 The sleeping bag I just use one from Walmart that was rated for like 20-30 degrees F or whatever because I like to sleep warmer (and some airports are colder than others). The sleeping bag is quite big, but fits fine in a carry-on https://www.costco.com/cascade-mountain-tech-ultralight-collapsible-cot.product.4000255068.html The cot is an unusual shape and making packing everything insanely difficult, but it's doable. I probably want to switch it out later Yes I just lay them in an inconspicuous area of the airport and sleep. My equipment is quite colorful so there's no hiding, but afaik, ORD is the only airport so far that'll wake you up and ask to see your flight the next day (morning flights, idk how they react to afternoon/evening flights)
