Fits 5+ days worth of clothing and if traveling by way of airplane, acts as TSA checked luggage. Perfect for longer trips and can easily be tossed in the trunk for a road trip, fitting both your and a partner's belongings. This duffle will survive anything you throw at it and should not be treated preciously. FYI: In the Primary collection, Go-Bags have non-detachable (like a backpack) shoulder straps.
