LL Bean makes very durable bags. Both Dry bags and luggage. We ditched suitcases many years back and only use the LL Bean duffle bags. Less weight and easily stores anywhere on a boat or hotel. My wife and I have the XL bag with hard bottoms for the rollers and the kids have the Large bags. Depending where we travel, we may steal the kids bags, if we don't need all the space. For sailing, the XL is nice for snorkeling gear on the bottom. I have used the dry bag while kayaking with good results.
