Belt size accommodates 32" - 46" waist The original. The classic. The one that started it all. We began Viking Leather with one goal: create the perfect, durable Tool Belt/Apron for the Professional Tradesperson. The 401 is an entry level Belt/Apron and is reflected in the pocket size. The nail pocket and tape measure pocket are smaller than average. It would well for a finishing Carpenter. The 401 model has smaller front pockets to accommodate those hard-to-find small tools. The 401 is the highest value pouch made with 100% Heavy Duty leather and Steel rivets for long-lasting durability. It's perfect for the Professional Tradesperson or home renovator.
