I'm going "caving" for a whole 7 day period.....it's an indoor cave, but, it's underground and the temp literally ranges from 32 degrees all the way to at least 80 degrees F, but, I have this lightweight jacket from Abercrombie I bought 3 of them for $29 on clearance a few weeks ago since it was the best deal and I think it's literally perfect for it, but, they said any jacket, pants, hats, gloves, etc will be extremely dirty from all the mud you'll be encountering throughout the cave, but, at the end of the cave tour (it goes from 6am to 10am), they will take all of our dirty/muddy clothing and will be washing and drying them for us. The only thing that I'm worried about is that my jacket is going to be getting shrunk since they will be washing and drying everything on the longest, hottest and most powerful cycle because they said it's the only way to make sure all the mud and dirt will be gone (they said that each family will share the same washer and dryer). They said washing will take around 3 hours and drying will take around 3 to 4 hours and they'll be calling us when the dryer has 30 minutes left so we can go back to get it.

What should I do? Should I go ahead and wear this lightweight puffer jacket since it's going to be both cold/wet in some parts and warm/wet in other parts of the cave? Do you think my jacket will shrink?!?!
