Hey Scorp21, welcome to the forum. Yes the Woobie is probably #1. Myself, DW, DD & DS also sleep with one every night instead of a bed sheet. Had to get different colors/camo so they'd stop fighting over em.

SIDENOTE: last winter my Godfather & I bought the Therm-a-rest Tech Blanket. It's nickname is, "Super Woobie", we both compared notes after some cold shoulder season sleeping and it did magnificent.
