Back to get dropped wear

When I unload small back pack, I found it open and a wear be dropped. As the fastener was loose, the back was opened.
The wear was most favorite one. And it was expensive. But, I'd be tired and I wanted to escape from mountain. So, I considered whether I would back to mountain in order to get the wear or not for a while.
As A result, I got it after I climbed again for about 30 minutes. It was hard job.
Climbing same road without long interval was not interesting.
