OutdoorMaster MIPS Bike Helmet, Gray, Size Large — Youth & Adult Cycling Helmet with 26 Vents and Two Removable Liners

OutdoorMaster MIPS Bike Helmet is a lightweight, ventilated adult cycling helmet with MIPS rotational protection and two removable liners for a customizable, secure fit across road, mountain and commuter rides.

Designed for riders who want versatile protection and comfort, this OutdoorMaster helmet pairs a Multi-directional Impact Protection System (MIPS) with an adjustable retention system and 26 aerodynamic vents. It works for commuting, road training, mountain trails, e-scooter trips or skate sessions, and the two removable inner pads let you tune fit and cushioning by season or preference. Built to fit most adults (50–62 cm), it balances safety features, breathability and low weight for longer rides.

How does the MIPS system improve helmet safety?

The integrated MIPS layer is engineered to reduce certain rotational forces transferred to the head in angled impacts. It provides a low-friction layer that allows slight relative movement between the helmet shell and your head, helping manage energy from oblique collisions. This is an added safety technology alongside the helmet’s EPS shell.

• Dedicated low-friction MIPS liner for rotational energy management
• Combines with a protective EPS core and outer shell
• Designed to work in many common impact scenarios

How do I get a precise fit for different head sizes?

OutdoorMaster uses a three-way fit system featuring vertical adjustment, a 360° dial and adjustable side straps so you can fine-tune height and circumference. That combination lets the helmet sit correctly on the head and remain stable during activity. The range accommodates most adult head sizes from about 50 to 62 cm.

• 360° rear adjusting knob for micro-fit changes
• Up-and-down shell positioning for proper helmet sit
• Adjustable side straps to secure chin and ear fit

Will this helmet stay comfortable on long rides or hot days?

Yes — the helmet is engineered to keep weight low and airflow high. Weighing approximately 278 g, it minimizes fatigue while 26 vents channel air across the head to reduce heat build-up. Soft, removable inner pads and a cushioned chin strap add comfort for extended wear.

• Super-light construction around 278 g for reduced neck strain
• 26 vents arranged for efficient airflow and cooling
• Soft, removable inner pads for washing or seasonal changes

Can I use this helmet for multiple sports and conditions?

The OutdoorMaster MIPS helmet is a multi-sport design suitable for road cycling, mountain biking, commuting, e-scooters, skateboarding and other non-motorized wheeled activities. Its ventilation and removable liners make it adaptable for warmer or cooler weather, and the adjustable fit suits different head shapes.

• Unisex sizing and styling for men and women
• Two removable liners for fit or comfort adjustments
• Versatile for commuting, recreational cycling and skate sports

Who is this for? Riders who want a balance of safety technology, lightness and ventilation—commuters, weekend road cyclists, light-trail riders and multi-sport enthusiasts—will appreciate the OutdoorMaster MIPS helmet. It’s particularly helpful for those who need an easily adjustable, washable interior and reliable fit across different activities and seasons. Always measure head circumference (about one inch above the eyebrows) to choose the best fit within the 50–62 cm range.
