I purchased this bag in the XL and L last year. The XL has been used more than the L, but they both have a musty/moldy/mildew smell. I have occasionally had damp towels, but then leave the bag empty to dry. It's a shame because I've tried using clorox wipes, leaving it inside out in the sun, and everything in between. It's a shame, because now I cannot use them to pack clothes in for risk of smell transferring. Any thoughts LL Bean?
