3 Bundle B55 Strings are made using 3 separate bundles of B55 string material & #62 serving for long life. Just the string for older bows & non fast flight capable bows.
The advantage of the 3 bundle construction is it give a perfectly round string for good nock fit & is a lot quieter than 2 bundle strings.
Try them out you will be impressed.
