Standard (M) 24.4 to 34.6 inches, Small (S) 21.25 to 27.6 inches or Strap extender PLEASE ENSURE YOU CHOOSE THE CORRECT REPLACEMENT STRAP FOR YOUR MONITOR Review: Genuine Brand Name replacement option - I was thankful to find this replacement strap available on desertcart for my MyZone heart rate monitor. I usually buy them from the MyZone website periodically, but standard shipping takes a while. It's genuine, and works perfectly. This is my 3rd replacement belt in 5 years of near daily use. The quality holds up for a long time. The elastic does begin to give towards the end of its lifespan but since it's adjustable, it's never a problem in getting the right fit. It also takes a long time before it begins to latch on to body sweat/odor. Definitely follow the directives in washing the belt in the sink after every use with warm water, and gently wring it out and air dry. And wash often in the laundry. I usually wash it between 1-2 times a week. Eventually as the belt ages, even soaking it in concentrated detergent/solution won't fully remove the understandable (at least in my experience) and totally normal odor that comes with the build up of sweat after long term use. So I do try to have 2 belts on hand at all times to alternate between through the week. If you need a replacement belt for your compatible heart rate monitor by MyZone, definitely go for it in buying it here. And buy two while you are at it. Review: Great replacement strap! - Original strap that came with my monitor finally snapped. This replacement worked great. ## Features - MEDIUM SIZING: Fits chest circumferences from 21.25"–27.5", supporting confident movement during all types of training. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07ZR4XTBZ | | Best Sellers Rank | #65,652 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #173 in Exercise Straps | | Brand Name | MYZONE | | Color | MZ-Switch | | Customer Reviews | 4.6 out of 5 stars 817 Reviews | | Item Weight | 20 g | | Manufacturer | Myzone | | Material | Elastine, Polyamide | | Model Number | m | | Number of Items | 1 | | Number of Packs | 1 | | Part Number | m | | Size | Medium | | Style | Modern | | Unit Count | 1 Count | ## Images ![Myzone Replacement & Extension Chest Straps – Adjustable Straps for, MZ-Max & MZ-3 (Small , Medium & Extender Options - Image 1](https://m.media-amazon.com/images/I/51e+fBxvkSL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Genuine Brand Name replacement option *by J***T on April 10, 2024* I was thankful to find this replacement strap available on Amazon for my MyZone heart rate monitor.

This replacement worked great. ### ⭐⭐⭐⭐⭐ Perfect *by J***M on June 12, 2025* I've had my monitor for about 2.5 years and recently it has started to not record here and there during my workouts. I thought maybe it was time to replace it, but read a couple of reviews about switching out the band and decided to try that first. I have used my new band several times now and it works like it is new. No more issues with recording my workouts. ## Frequently Bought Together - MYZONE Chest Straps - MYZONE MZ-3 Replacement Charging Cable --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hu/products/535979119-myzone-replacement-and-extension-chest-straps-adjustable-straps-for-mz](https://www.desertcart.hu/products/535979119-myzone-replacement-and-extension-chest-straps-adjustable-straps-for-mz) --- *Product available on Desertcart Hungary* *Store origin: HU* *Last updated: 2026-08-16*
