Helmet size chart

These size charts and conversions are a guide. Try on your helmet before riding to check comfort and fit.

How to measure your size

Wrap a measuring tape around your head, keeping the tape level from front to back. Compare your head circumference with the guide below.

With the fit system loose, allow a little room. The helmet should sit low enough to protect your forehead without obstructing your vision. Adjust the fit system once you have the correct size.

This is the general Giro helmet guide. Available sizes depend on the model. Select only a size listed for this product.

Description

Lighter, cooler, sleeker, plus all the added protection of Spherical Technology powered by Mips and our new DryCore sweat management system: the Aries Spherical is like nothing before.

Details

A helmet that feels like it isn't there: the all-new Aries™ Spherical is like nothing before. Its sleeker form and lighter weight (only 270 grams in size medium, CE certification), deliver sensational comfort and cooling power. Spherical Technology™, our ball-and-socket design powered by Mips®, adds protection by redirecting energy away from the brain in certain impacts, and Progressive Layering with dual densities of Nanobead EPS foam adds more comprehensive energy management. 24 Wind Tunnel vents are maximized by the AURA II Reinforcement Arch, while a plush DryCore™ brow pad manages sweat and combines with a network of intricately engineered deep internal channeling to elevate comfort. From the proven reliability and adjustability of the Roc Loc® 5+ Air fit system, to full lower hardbody coverage to enhance durability, to the meticulous production quality, the Aries is state-of-the-art performance, protection, and style.

Warranty & Return

  • Please choose carefully: Before purchasing tents, sleeping bags or other outdoor gear, check the dimensions, specifications and suitability for your intended use. Contact us if you need help choosing.
  • Change-of-mind returns: Contact us within 14 days of delivery. Items must be unused, clean, complete and returned with their original packaging. For eligible change-of-mind returns of tents, sleeping bags and similar outdoor products that have been unpacked and cannot be restored to their original factory-packed condition, a 10% restocking fee applies. Return shipping is at your expense. Opening an item for inspection is different from using it; returned items must still meet our return conditions. These fees and conditions apply only to change-of-mind returns. See our Returns Policy.
  • Faults & warranty: If your outdoor gear has a fault, arrives damaged or does not perform as it should, contact us with your order number, a description of the issue and photos where possible. We will assess the issue and arrange the appropriate remedy. Any manufacturer’s warranty is additional to your rights under Australian Consumer Law.
  • Outdoor use & care: Normal wear, accidental damage, misuse, unsuitable storage and failure to follow care instructions are generally not covered by a manufacturer’s warranty. We assess each issue individually; this does not exclude a remedy where Australian Consumer Law applies. Follow the manufacturer’s instructions for setup, cleaning, drying and storage.
  • Your consumer rights: Our goods come with guarantees that cannot be excluded under Australian Consumer Law. You are entitled to a replacement or refund for a major failure and compensation for any other reasonably foreseeable loss or damage. You are also entitled to have the goods repaired or replaced if they fail to be of acceptable quality and the failure does not amount to a major failure. Change-of-mind time limits, packaging requirements and restocking fees do not limit these rights. See our Warranty Policy for more information.
