We have a double sleeping bag from Nemo that has the attached care tag. Admittedly, we haven’t washed it before and I’m nervous. We have a front load washer but it’s not commercial sized and I wonder if anyone has put a big double sleeping bag into a laundromat washer and dryer and it’s survived? Anyone have any advice? It definitely needs a wash after being in several sandy situations the past two years. TIA!
