blue open face motorcycle helmet Westt Helmets, with Built-in Sun Visor - DOT Approved The helmet is made from moisture RetroRide Smart Bluetooth Open-Face Motorcycle

Here is the product link, if you want to know the actual specs

A slight downside is the backplate adds a little weight, but as you can see from the table I put together below, the fluid weighs far more than the hydration bladder, so you won't notice too much of a difference in overall weight

This is making a solid object in layers, so for a helmet, it can be customized to a persons head or specifications

A true go-anywhere helmet with a low-profile lightweight design, extra rear coverage, and a mini visor for a relaxed, modern look for all rides

You still get a respectable-but-not-staggering number of ports, too: three USB 3.0 (two on the left, one on the right), a full-size SD card reader, a headphone jack, and a micro HDMI port

I find them a livable compromise between protection and weight/bulk
