Bushwhacker 2VI Mips Helmet

What Our Gearhead® Experts Are Saying:

"I've tested the Bushwhacker 2VI MIPS across full enduro race days and the 2vi shell architecture is a meaningful differentiator — the variable elasticity construction responds differently to high-energy impacts than a standard single-shell design, and combined with MIPS Air the rotational protection here is as thorough as anything I've worn in this category. The 360 Occigrip retention system holds the helmet precisely in place through the hardest hits and most aggressive body positions, and the Fidlock magnetic buckle is one of those details that sounds minor until you've used it and can't go back."

Trail and enduro riding at speed places demands on a helmet that go beyond the impact scenarios most lids are designed around — the crashes are faster, more varied in angle and force, and more likely to involve the oblique and rotational mechanics that single-axis impact testing doesn't fully capture. The Sweet Protection Bushwhacker 2VI MIPS Helmet is built to address that full range of crash mechanics rather than optimizing for a narrow standard, drawing on Sweet Protection's deep background in snow sports protection engineering to bring a more sophisticated impact management system to the mountain bike category.

The structural core of the Bushwhacker 2VI MIPS is the 2vi Technology shell, a 4-piece variable elasticity injection molded construction that uses different material stiffness values across zones of the helmet to respond appropriately to impacts of varying energy and direction. This architecture works in combination with a multi-density EPS liner that further tailors impact absorption at different locations across the helmet, allowing the system to manage both high-energy direct impacts and lower-energy but more dangerous rotational loads more effectively than a uniform single-shell design. MIPS Air adds a low-friction slip-plane layer between the helmet and the rider's head, reducing the rotational forces transmitted to the brain during angled impacts. Together, the 2vi shell, multi-density EPS, and MIPS Air form a three-layer protection architecture that operates across a wider range of real-world crash conditions than any single technology addresses alone.

Thermal management is handled by the STACC ventilation system, engineered to direct airflow through the helmet with particular attention to the superficial temporal arteries — the vascular structures on the sides of the head where heat transfer to and from the brain is most efficient. Keeping those areas cool during sustained trail efforts has a measurable effect on comfort and cognitive performance over the course of a long ride or race stage. The 360 Occigrip Fit System provides full-perimeter retention that wraps the head at the occipital level and adjusts to hold the helmet stable through aggressive body positions, hard braking, and the sudden directional changes of technical singletrack. The magnetic Fidlock buckle closes and releases with a single hand in a fraction of the time required by traditional buckle systems, a practical advantage in trail contexts where gloves, mud, and fatigue all complicate fine motor tasks. An adjustable visor adds versatility for changing light conditions and doubles as goggle retention between runs or on mixed-effort days. The Bushwhacker 2VI MIPS meets U.S. CPSC certification standards and is backed by a two-year manufacturer warranty.
