We strive to get you the gear you want at a competitive price. If you find an item we offer from a competitor at a lower price, let us know. We will do our best to instantly match their price. To qualify for the Price Match, your purchase must meet the following conditions:
Price Matches may only be honored on identical items. The product must be the same make and model (i.e., the same size, color, year, etc.).
The identical items must be in stock and ready for immediate delivery at the competing dealer.
Price Matching voids any currently advertised Jenson USA promotions or special offers (i.e. free shipping, free headset...). If the competitor offers free shipping on the specific item, Jenson USA will still match the price and free shipping offer.
The product must be brand new. We do not Price Match refurbished or used items.
Our Price Match Policy is valid only for qualified Internet retailers.
The competing dealer must be an authorized US retailer for the brand. This means that the manufacturer lists this dealer as an authorized and official retail web site.
The competing online retailer's principle business must be located within the United States.
Our Price Match Policy does not combine with any competitor’s coupons, rebates, promotional offers, or product-combo deals on your order.
Some items may not be eligible for price match due to manufacturer pricing requirements.
The Price Match Policy is subject to change at any time.
If you have any questions regarding a Price Match, one of our Gear Advisors will be happy to lend you expert guidance via phone, email, or chat.
Price Matches made post-purchase will be refunded via gift card
The Giro Aries Spherical Helmet is designed with top-knotch protection, exceptional airflow, and modern styling in mind, for wherever the roads take you. At the heart of the Aries is the MIPS® Spherical Technology, a ball-and-socket design that redirects rotational impact forces from certain angled impacts. This protection continues with the dual-density EPS foam for high and low-speed impact absorption, and an Aura II Reinforcement Arch for improved structural integrity. This results in the Aries Spherical being Virginia Tech’s #1 safety-rated helmet they’ve tested so far. The featherlight Aries also boasts 21 Wind Tunnel vents and Deep Internal Channeling to direct a high volume of air over the head, keeping you cool while keeping you safe.
Spherical Technology powered by MIPS® is a ball-and-socket design that allows the inner and outer helmet layers to rotate separately, absorbing rotational forces during certain impacts
21 Wind Tunnel vents with Deep Internal Channeling provide a wind tunnel effect, for a massive amount of cooling airflow throughout the helmet
Aura II Reinforcing Arch improves the structural rigidity of the helmet while allowing for oversized vent ports
Eyewear docking ports with rubber grippers keep your glasses securely stowed on your helmet during extended climbs or in changing light conditions
Roc Loc® 5+ Air Fit System combines easy helmet retention with optimized airflow by suspending the helmet slightly above the rider’s head
Progressive Layering™ uses two densities of EPS foam to protect from both high and low-speed impacts
