What Our Gearhead(R) Experts Are Saying: "I've rotated the Grimnir 2Vi Mips Helmet into storm and bluebird days, and the carbon shell-to-weight ratio is noticeable the moment it's on. The Occigrip dial locks in a low-profile fit, the fixed vents keep temps in check, and the Mips layer adds confidence when things get rowdy. It runs a touch snug-if you're between sizes, I'd size up."We count on the Sweet Protection Grimnir 2Vi Mips Helmet when we want maximum protection without extra bulk. Sweet Protection's thermoplastic laminated carbon shell keeps weight low yet feels rock solid on the chair, the traverse, and in tight trees. Add in the Mips low-friction layer and multi-impact EPS, and we get advanced protection from both rotational and direct impacts while we chase fresh lines. Comfort is dialed, too. The Occigrip fit system fine-tunes stability with gloves on, four strategic vents regulate heat on back-to-back laps, and the slim, goggle-compatible silhouette plays nicely with modern frames. Audio-ready ear pads make it easy to add tunes or a comms drop-in for resort days. If you sit near the top of a size range, consider sizing up for the best fit-this lid runs on the snug side.
