Giro Tyrant Spherical MIPS Helmet

Unlike traditional MIPS liners that sit against your head, Spherical technology uses a ball-and-socket design where the outer shell rotates independently around the inner liner. This allows the helmet to redirect impact forces more effectively while eliminating the plastic slip-plane liner that can sometimes cause hair pulling or heat buildup.

No, it is a hybrid design. It offers significantly more coverage than a traditional half-shell helmet, particularly around the ears and the back of the head, but it lacks the chin bar found on full-face models.

Yes, the Tyrant is specifically designed to be eyewear-compatible. The adjustable visor allows you to tilt it upward to stash goggles, and the internal shape is sculpted to accommodate the arms of most riding glasses without interference.

While it offers more coverage than a standard trail helmet, it features 14 vents with internal channeling designed to pull air over your head. It will run slightly warmer than a minimalist XC helmet, but it is well-ventilated enough for all-day trail riding.

Yes, the internal padding is removable. This makes it easy to wash away sweat and grime after a long ride to keep the helmet fresh.
