Got a long walk with your harness on? It can be a LOT more comfortable to push the leg loops off to the side. Doing this avoids any chafing from the leg loops on sensitive anatomy.
My partner and I were at the trailhead at daybreak, ready to hike in a couple of hours to a moderate five or six pitch alpine rock route in the Sierra backcountry. We had an early start, there were streams for water on the approach and hike back, it was going to stay light late into the evening, and the weather forecast was dry and sunny.
The route was up a long ridge and down the other side, so bringing two backpacks and leaving one at the base was not going to work.
We opted to bring one small pack that the second carried on route, and could be hauled on steeper pitches if necessary. The pack barely fit the rack, two wind shells, and a few snacks. There was no room for shoes, the rope or harnesses. So, we wore the harnesses on the hike in. One person carried the pack, and the other backpack coiled the rope.
Many harnesses have a plastic clip on the back of the leg loops. Unbuckling this clip can make this even easier.
