Yonex BG80 is a mid-gauge badminton string at 0.68mm, striking a balance between the extra durability of thicker strings and the added feel and spin of thinner ones. It's a solid middle-of-the-road option for players who want a crisp, powerful response without sacrificing too much string life — well suited to club players and intermediates who play regularly but don't want to restring every week. Thinner than an all-durability string like the BG65, it offers noticeably more bite on the shuttle for spin and touch shots, while still holding tension better than the thinnest tournament-grade options. Each reel is a 10m set, enough for a full racquet stringing, and it comes in multiple colors.
