$65 GBPCondition: SEE IMAGES PLEASE

Comes from a smoke-free, pet-free home.
Lightly used as sizing was incorrect when first purchased and I failed to return within the time frame.
The scratch on the back was due to the helmet being left on the handle bar and then it scraped against the wall so superficial and absolutely not due to any impact. I was going g to cover with a nice sticker.
Any questions, feel free to message me!
A fantastic lid for trail, enduro, or urban riding.
The peak can be removed for skateboarding snowboarding yet still look great.

Giro was founded in 1985 by Jim Gentes, with obsession for design and answering unmet needs. That obsession led him to start making his own products and ultimately resulted in a company committed to serving the rider through personal expression and advanced performance.
Tyant™ Mips® Helmet is designed to meet the needs of today's progressive trail riders. Equally at home on forest singletrack and at the dirt jumps, Tyrant's attitude ushers in the modern era of mountain biking.
While the style is understated, the Tyrant boasts countless under-the-hood tech breakthroughs including Wind Tunnel Ventilation and Mips Spherical technology. Mips Spherical utilizes a pair of foam layers that work like a ball and socket to redirect impact energy in a crash. One layer is EPS, which is well suited to high-speed crashes. The other is a lower density EPP foam with rebound characteristics to address low-speed, roll-around-in-the-dirt-type spills. The added coverage of this "full cut" design further enhances protective capability, while taking helmet design in a new direction for riders seeking style over speed.
Features
Cheek Pad Ventilation
Allows cool, fresh air to circulate inside the helmet to help cool you, and to address sweat management.
Hardshell With In-Mold hardbody™ Lower Wrap
The two-piece shell combines a tough outer hard shell with a polycarbonate lower shell permanently fused to the liner for durability without excess weight.
Spherical Technology
Spherical Technology's Ball-and-Socket design, powered by Mips®, helps redirect impact forces away from the brain by allowing the outer liner to rotate around the inner liner during a crash. It also eliminates contact with hard plastic or slip-planes against the skin.
Progressive Layering™
Two different materials are used to manage impact energy: One layer is EPS which is well-suited to high-speed crashes. The other is a lower-density EPP foam with rebound characteristics that address the more common, low-speed impacts.
Roc Loc® Air DH Fit System
This revolutionary fit system adds a new dimension to helmet performance by enhancing cooling, as well as fit comfort and stability. Using a patented design that suspends the helmet just slightly off the top of the skull, Roc Loc® Air DH allows cool airflow to pass directly over your head, further enhancing the performance of vents and internal channeling that exhaust heat out of the helmet. Fit and feel adjustments mimic the Roc Loc 5, allowing you to easily custom tune fit tension and fore-aft tilt of the helmet in seconds using a single hand.
Tool-Free Bolt-On Visor
Easily adjustable without need for tools or extra fiddling, and offers plenty of vertical adjustment to stage goggles when you're not wearing them.
Stack Vent Technology
Vents at the brow line help warm air to be drawn up and away from your goggles to eliminate fogging, while allowing seamless integration with goggles.
