Review: Indirect eye protection upgrade for your helmet - This is a feature that should have come standard from HJC, but cost savings help HJC meet their price point I guess Chin curtains can help minimally with cold, but that is not the point The breath guard is intended to prevent fogging, and a pinlock insert can be added if fogging is a serious issue for you. Chin curtains are meant to cut down on wind noise, but mostly to prevent air/dirt/bikes from entering the helmet and messing with your eyes This chin curtain does exactly that It is not uncomfortable, but is very functional Install is not necessarily hard, but it does require some effort. Because the helmet did not come standard with it, you need to loosen the glue around the edge to allow to hard "blade" of the chin curtain to slide into the helmet frame. Make sure to push it in centered the first time, and make sure to push the "blade" all the way down to flush with the edge seal. The beauty is that you have to install it only once, so this is not an issue Get yourself one and you will love it Review: Fit HJC C70 Small & reduced wind noise - The circulation in this helmet is a bit much for me. This curtain helped out a lot. I wear earplugs, but this also adds quite a bit of sound dampening. The insertion into the lining was a little tricky. I went from one side to the other as I didn't have luck starting in the middle, as I saw on some YouTube tutorials. It's not perfect, and I could probably pull it out and trim the plastic a bit to make it sit more flush, but I don't think it will move the way it is. Certainly worth it IMO. ## Features - Prevents fogging by deflecting Air Inlet - This helmet is DOT approved and FMVSS 218 certified for legal on-road motorcycle use in the United States. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00SXH866C | | Additional Features | Ventilation | | Age Range (Description) | Adult | | Age Range Description | Adult | | Best Sellers Rank | #1,167,268 in Automotive ( See Top 100 in Automotive ) #634 in Powersports Helmet Hardware | | Brand | HJC | | Brand Name | HJC | | Color | Black | | Customer Reviews | 4.2 out of 5 stars 63 Reviews | | Included Components | not_applicable | | Item Dimensions | 6 x 4 x 1 inches | | Manufacturer | HJC | | Manufacturer Part Number | 0918-3705-00 | | Model Name | Chin Curtain for IS-17 Helmets | | Model Number | IS-17 CHIN CURTAIN | | Number of Items | 1 | | Outer Material | Polycarbonate (PC) | | Product Style | Street | | Recommended Uses For Product | Motorcycling | | Size | One Size | | Special Feature | Ventilation | | Unit Count | 1 Count | ## Product Details - **Brand:** HJC - **Color:** Black - **Age Range (Description):** Adult - **Size:** One Size - **Special Feature:** Ventilation ## Images ![HJC IS-17 Chin Curtain Mouthpiece Street Motorcycle Helmet Accessories - Black/One Size - Image 1](https://m.media-amazon.com/images/I/8101XYZy1qL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Indirect eye protection upgrade for your helmet *by R***. on February 23, 2017* This is a feature that should have come standard from HJC, but cost savings help HJC meet their price point I guess Chin curtains can help minimally with cold, but that is not the point The breath guard is intended to prevent fogging, and a pinlock insert can be added if fogging is a serious issue for you.

This curtain helped out a lot. I wear earplugs, but this also adds quite a bit of sound dampening. The insertion into the lining was a little tricky.

Certainly worth it IMO. ### ⭐⭐⭐⭐⭐ Works for the C70 helmet as well *by J***N on December 25, 2020* This chin curtain works for the C70 as well as the is-17. This is a Must-Have for fall and winter riding!! It decreases The wind by maybe 40%. This makes a huge difference! It took me about 10 minutes to put it in. However, once it is in, it is very solid and will not come out on its own. You have to work it in as the helmet was not made for chin curtains. Once you get the front of it in the rest of it slides in easily. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/33374821-hjc-is-17-chin-curtain-mouthpiece-street-motorcycle-helmet-accessories](https://www.desertcart.us/products/33374821-hjc-is-17-chin-curtain-mouthpiece-street-motorcycle-helmet-accessories) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-09-01*
