The unique segmented bodies that are found in the Berkley Sqwormer series produce an enhanced ultra-limber action that’s genuinely new to the bass market. The lures are also impregnated with Bio-Salt, which simulates the salt content of live prey and which lab studies show bass prefer 100 percent over table salt. Sqwormers come in 4-,7- and 10-inch worms, plus tube, lizard, craw and paddler styles.
