Top tube bags are designed to offer easy access on the go to smaller items such as valuables, snacks or low bulk layers such as arm warmers - they make a good alternative be used instead of stuffing your jersey pockets or a saddle bag.
Capacity wise, Restrap’s Race Top Tube Bag sits in the middle of the sizes on offer by bikepacking bag brands. 1.5 litres is a useful amount of storage space and one advantage of going for something a bit smaller is that you’re less likely to hit your knees on it.
