DoubleTwist barbags work great with RePack seatbags to create a balanced load on your bike. Using a high volume barbag in conjunction with a seatbag to carry your gear on bikepacking trips allows you to use a smaller or reduced volume seatbag, instead of just using a larger seatbag alone that extends further behind your saddle and would negatively affect your ability to get behind the seat on a steep downhill. The load balance of using a seatbag and barbag together also really helps when tackling steep uphills and technical trails.
