Im going to try and recapture my youth this fall and have pulled out my nearly 10 yro Gregory palisade 80 to clean. The pack is in excellent condition but hasn't been used in about 4 years and parts of the inside are peeling or sticky.
How do I clean this up or repair it? The sticky/peeling material in question is about 20% of the inside of the pack. Pic here is example of peeling.
