My last one like this. IT IS NEW, no usage, no scrapes etc. Fits about 1-3 days worth of clothing and if traveling by way of airplane, acts as a TSA approved personal item. It's lightweight and agile, yet just as strong as the bigger versions. Built for overnight adventures, road trips and beach hangs. I do not know Liter Size, sorry. Please see picture for Measurements or ask for more measures if needed.
