on time delivery. bag looks pretty good and excellent quality. capable of 21 litres not so big. would be suitable for 3 days travel. the only thing is trolley is occupying more space and it is bit heavier. overall worth to buy.
A worth buying bag . Don't get confused with size ,this bag is well comfortable packing for a 3-4 days trip. So, If this is the size you are looking for .. don't make late just buy because the quality is just awesome. I'm editing this review after 6 months of use ... everything is okay but the threads started coming out !
