Review on 🚴 BTR Waterproof Helmet Cover with Reflective Stripes - Universal Size Bike/Bicycle - High Visibility - One Size Fits All by Tim Wadman

I drive about 25 minutes (one way) to work and wanted to keep my head dry enough. This helmet cover doesn't fit me. I saw other reviews and hoped but even the light is straight on for 25 minutes which gets my helmet and head wet. This cover is better than nothing, but even in light but persistent rain, the interior seeps through fairly quickly (<15 minutes). This moisture under the helmet cover is not condensed sweat as I have also tested this cover several times in dry conditions with temperatures similar to rainy days and the underside of the cover is dry. In heavy rain, the rain actually collects on the clumped bottom edges of the cover, resulting in 1-2 ounces of trapped water. (that is, don't take your helmet off indoors on the carpet). Good* Fits well (men's Giro Revel), even in windy conditions (gusts up to 30mph)* Visible downside* Doesn't really block rain (not waterproof)
