WHAT OUR CUSTOMERS SAY
FAQ
WHAT PAYMENT METHODS DO YOU ACCEPT?
We accept all major Credit Cards, PayPal, and Apple Pay for a seamless and secure global checkout.
IS THE STORE SECURE?
Absolutely. Our entire site and checkout process are 100% encrypted, ensuring your data is completely protected.
HOW DO I FIND MY HELMET SIZE?
Every head is different. To find your perfect low-profile fit, wrap a soft measuring tape around your head, about 1 cm above your eyebrows and ears. Compare your measurement directly with the size chart on our product page. If you are right on the edge between two sizes, we always recommend going one size up for maximum comfort.
DO THEY HAVE A BULKY LOOK?
Not at all. These are explicitly designed as ultra-low-profile shells. They sit deep and tight on your head, completely eliminating the bulky "bobblehead" or "mushroom" look.
IS THE INNER LINER REMOVABLE?
Yes, the inner comfort padding is fully removable and washable. It features high-grade moisture-wicking fabric to keep your head dry and cool during long highway rides.
IS THE PRICE WORTH THE QUALITY?
Absolutely. We cut out the middleman to deliver direct to your garage. Our helmets feature premium injection-molded shells, multi-density EPS impact absorption, and high-grade tailored liners that compete directly with brands twice the price.
WHAT IS YOUR RETURN POLICY?
We’ve got you covered. We offer a solid 60-day return and exchange window from the date you receive your order. Whether you need a different helmet size or a different style of suit, the item must be completely unworn, scratch-free, and in its original packaging.
DO THE SUITS ALLOW FULL MOBILITY?
Absolutely. Our jumpsuits and riding suits are explicitly tailored for the riding position. They feature relaxed shoulders and reinforced back seams, ensuring the fabric doesn't pull or bind when you reach for high risers or lanesplitter bars.
HOW DO I TRACK MY ORDER?
Once your premium kit passes the final detail check and ships, you will receive an email with a real-time tracking link
IS BUYING A HELMET ONLINE RISK-FREE?
Completely. Aside from our bulletproof 60-day exchange policy, every single lid is packed inside a high-density protective box with double padding. We guarantee your helmet will arrive at your door in absolute mint, flawless condition.
