SFI 3.3 Rated (Tags Affixed); Adult Lightweight Aramid and FRC Blended Fabric Superior Moisture Wicking Properties Hypoallergenic - Won't Irritate Skin Soft and Supple Knit Fabric Dries Quickly Seams are Strategically Placed and Flat Sewn for Comfort Machine Washable Review: Solid SFI balaclava at a fair price - Needed a certified balaclava for HPDE events and this one checks all the boxes without costing a fortune. It fits snugly under my helmet without bunching up and breathes better than some of the thicker options I tried. The SFI 3.3 rating is what the rulebook requires so there's no worrying about tech inspection. Good piece of safety kit that I reach for every track day. Review: Comfort is prioritized. - (Disclaimer, I removed the RaceQuip logo in the front with a seam ripper. But rest assured, this is the very same item.) First of all, this is a great head sock. I intend to use it for a cosplay which involves wearing a helmet and a gas mask on top of that, which I tested. Easy compatibility with both. It’s thin enough to support other head accessories like racing helmets, which obviously it’s intended for. It’s also VERY easy on your face. Firstly, the material is VERY soft and comfortable. No annoying seam going over the mouth, either. It’s a perfect fit, tight enough to hug your face just ever so slightly, but loose enough to get comfortable mouth movement. The eyehole is also excellently cut. Large enough so that practically nothing obstructs your view, but still enough material to guarantee that it goes over your nose without fear of it falling down. You can also pull the nose part down below your chin if you wanted. It also seems as though the neck covering is the perfect length. Just enough to cover the entire neck and get tucked under a shirt. And finally, the breathability is fantastic. Light and easy. Everything about this head sock feels as though it was meticulously and considerately designed for user comfort and applicability, and everything about it hits the Goldilocks zone for me. Just right. It does exactly everything it’s supposed to do. If I ever lose this one or it somehow gets damaged, I know where I’m coming for round two. ## Features - 100% Polyester - Made in the USA - Lightweight Aramid and FRC Blended Fabric - Superior Moisture Wicking Properties - Hypoallergenic - Won't Irritate Skin - Soft and Supple Knit Fabric Dries Quickly - Seams are Strategically Placed and Flat Sewn for Comfort - Machine Washable ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B06XT8T5HS | | Additional Features | Lightweight | | Age Range Description | Adult | | Apparel Fabric Stretch | Medium Stretch | | Apparel Fabric Weight Class | Lightweight | | Best Sellers Rank | #326,098 in Automotive ( See Top 100 in Automotive ) #60 in Racing Apparel | | Brand Name | RaceQuip | | Color | Black | | Customer Reviews | 4.8 out of 5 stars 465 Reviews | | Fabric Type | 100% Polyester | | Fit Type | Universal Fit | | Fit to Size Sentiment | Good | | Global Trade Identification Number | 00887753073792 | | Hat Form Type | Beanie | | Included Components | RaceQuip Underwear Head Sock Balaclava SFI 3.3 Fire Retardant FR Single Layer Hood Black Large 433991 | | Is Waterproof | false | | Item Dimensions | 8 x 11 x 1 inches | | Item Type Name | RaceQuip Underwear Head Sock Balaclava SFI 3.3 Fire Retardant FR Single Layer Hood Black Large 433991 | | Item Weight | 0.1 Pounds | | Manufacturer | Racequip | | Manufacturer Part Number | 433991 | | Manufacturer Warranty Description | Warranty | | Material Type | Polyester | | Number of Items | 1 | | Occasion Type | Birthday, Christmas | | Pattern | Solid | | Pattern Style | Solid | | Product Care Instructions | Machine Wash | | Recommended Uses For Product | outdoor | | Seasons | Year round | | Sleeve Length Description | Sleeveless | | Sport Type | Motorsports | | Style Name | Apparel | | Style Number | 433991 | | Sun Protection | 2E+1 Sun Protection Factor (SPF) | | Theme | Sport | | UPC | 887753073792 | | Unit Count | 1.0 Count | | Water Resistance Level | Not Water Resistant | | character | Sports | ## Images ![RaceQuip® 433991RQP Head Sock - Single Eyeport - SFI 3.3 - Single Layer - Black - Image 1](https://m.media-amazon.com/images/I/71ADNpaYT5L.jpg) ![RaceQuip® 433991RQP Head Sock - Single Eyeport - SFI 3.3 - Single Layer - Black - Image 2](https://m.media-amazon.com/images/I/610FWO--eLL.jpg) ![RaceQuip® 433991RQP Head Sock - Single Eyeport - SFI 3.3 - Single Layer - Black - Image 3](https://m.media-amazon.com/images/I/612quBYBPBL.jpg) ![RaceQuip® 433991RQP Head Sock - Single Eyeport - SFI 3.3 - Single Layer - Black - Image 4](https://m.media-amazon.com/images/I/61Sp0X-62AL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by P***R on September 9, 2021* ### ⭐⭐⭐⭐⭐ Review *by G***D on May 8, 2024* ### ⭐⭐⭐⭐⭐ Review *by M***C on April 2, 2026* ## Frequently Bought Together - RaceQuip Underwear Head Sock Balaclava SFI 3.3 Fire Retardant FR Single Layer Hood Black - Permatex 81630 Ultra Red RTV Silicone Gasket Maker, Suitable for Exhaust Manifold, Header, Turbochargers & Slip Fit Exhaust Parts, Temperature Resistant (up to 343°C), Sensor Safe, Non-Corrosive 85g --- ## 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.us/products/47592391-racequip-433991rqp-head-sock-single-eyeport-sfi-3-3-single](https://www.desertcart.us/products/47592391-racequip-433991rqp-head-sock-single-eyeport-sfi-3-3-single) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-05*
