Berkley Gulp! Alive! Crawlers are infused with Gulp! Alive! attractant for ultimate fish-captivating power. Nightcrawler design wiggles with perfect live-bait imitation, but soft plastic construction lasts much longer. Ideal for jig or drop shot rigs for bass, and crawler rigs for walleye, the Gulp! Alive! Crawlers' 4'' size makes it ideal for clear water when a downsized presentation can make a big difference. Because the Gulp! Alive! Crawlers actually live in Berkley's "Magic Gravy", Gulp! Alive! attractant, they absorb 20% more attractant and are 20% more potent. And when you're done catching, simply put the Crawlers back in their live well to marinate in the potent Gulp! Alive! attractant to recharge for another day. Size: 4".
