The 4" wide strap was a significant improvement over my original 2.5" wide strap. I just completed a band tour of 6 nights straight, playing 2 hour shows, plus the numerous rehearsals leading up to the tour. The comfort increase and pain level decrease delivered by this strap was very noticable. The product quality is great and it was easy to add the Dunlop Straploks. Plus, the team at Italia was very supportive and responsive. They earned this 5 star rating and I recommend them!
