I've had a few Springbar canvas duffels for camp gear and stuff. I had been using this smaller duffel for travel. It's perfect to use as an overflow bag if I need to throw clothes in there to make room in my checked bag for trinkets. My one complaint is that it only had handles and I couldn't add a shoulder strap. I bought this larger duffel and it's the perfect size for carry on or to be a checked bag.
I was looking at the Fjallraven canvas duffel but they wanted $95 for it. Then I remembered Springbar and it was less than half the cost for the same quality. This size is perfect because it can easily be a carry-on, checked bag, or I can throw it over my motorcycle and use it for weekend rides. I'm very pleased with it!
