My DH uses an Ortlieb Ultimate 5 handlebar bag for his DSLR. He has a camera backpack for hiking and travel, although most of the time he just uses a shoulder strap when we're hiking and wraps it up in one of our backpacks when it's not in use. The camera backpack is pretty heavy when it's fully loaded.
Live with intention. Walk to the edge. Listen hard. Practice wellness. Play with abandon. Laugh. Choose with no regret. Continue to learn. Appreciate your friends. Do what you love. Live as if this is all there is.
