Where in Colorado are you from? We live outside of Vail. I recommend Patagonia Black Hole rolling duffle bags. They are made of a durable water resistant fabric. We have one of these for “boat stuff” that we check. I think it’s either 75 or 100 liters. Then my husband and kids all have the duffel that you can wear as a backpack for their stuff. This is a carry on. I have the rolling carry on because I had shoulder surgery years ago and couldn’t carry my bag on my shoulder. Love them all! We have even used the small duffles for rafting trips and they kept out the water.
