Baby Sling BUDDY BUDDY OSHIRI SUPPORI Buddy Buddy Oshiri Suppori Sling, Size L This size is perfect for women. It may be a bit small for men. I only tried it on once and just carried it in my bag. I never actually used it, and my child outgrew it. This product only requires one hand to support the baby, so I think it would be useful for carrying children who feel heavy, even for short periods or when they are small.
