Proudly made in the USA, this innovative solution combines durability and style, ensuring you look your best in any professional setting. ## Description Shirt Lock is made of a flexible, hook on hook material that is worn over your shirt and under your pants, about 2" below your waistline. The belt grips both the shirt and the pants, holding your shirt tails down and your pants up. Shirt Lock was developed for men and women. Whether it be for business, military and police uniforms, Scouts, school, sports, or ROTC Shirt Lock will keep you looking tailored and professional. It's a great alternative to suspenders, shirt stays, or the rubber belt. We recommend the 1.5" width for officers wearing a Duty Belt as it provides extra support. Shirt Lock recommends the 40" belt for waist sizes up to 40" and the 50" for waist sizes up to 50". Do not use on silk or wool Review: Best Shirt Keeper I've Used So Far - I have been using this for a couple of months now, and I can report that it does a great job. I use this to keep my uniform shirt tucked in and it works perfectly. I have been using the rubber belt style shirt keepers for years, and they usually last no more than a year before the holes start tearing. This is sturdy and I have a feeling it will last for years. Very happy with this purchase and very happy with it's performance. Review: Good but wore out too fast - I really enjoyed this product when I first got it. It held my shirt great. However, I have been wearing everyday for about 2 months and it has begun to wear out. It doesn't grip as well anymore, and the elastic area is stretched. I am not sure it's worth $20 every 2 months. Needs just a little better quality in thickness of belt and grippyness. ## Features - Shirt stay belt by Shirt Lock will keep your shirt tucked in all day! - Velcro-type material grips the nap on your shirt holding it in place! - If you've ever worn shirt stays or the rubber belt, you'll love Shirt Lock! - Worn as an undergarment belt, completely hidden from view! - For Police, Military, Everyday Professional or Casual, or Sports! ## Technical Specifications | Specification | Value | |---------------|-------| | Care instructions | Machine Wash | | Fabric type | 100% Nylon | | Origin | Made in USA | ## Images ![Shirt Lock Undergarment Belt Alternative to Shirt Stays 1"x 40" - Image 1](https://m.media-amazon.com/images/I/61CjIx9F34L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Best Shirt Keeper I've Used So Far *by C***S on January 10, 2015* I have been using this for a couple of months now, and I can report that it does a great job.
