Pant pocket for carrying a kickstand puck.

I sling a [url=https://www.etsy.com/listing/208295277/leather-bag-15-x-11-leather-satchel?ga_order=most_relevant&ga_search_type=all&ga_view_type=gallery&ga_search_query=leather%20messenger%20bag&ref=sr_gallery_17]leather messenger bag over my back when I need to carry more than that.
