DESIGNED TO BE FAST, AND COOL! The Wasp Air Tri is a shorter version of the original Wasp helmet, designed to meet the needs of triathlon riders. Everything about the helmet is shaped around the rider’s position and finding the maximum aerodynamic gains while being ventilated. The aerodynamic performance of the Wasp Air is the result of extensive wind tunnels research, scientific insight in aerodynamics and the use of mathematical models that allow Lazer to compute and optimize the shape of the helmet in the virtual environment. On top of the helmet, there is an Aquaport that allows water to be squirted in the helmet, where it quickly and effectively cools the head. Besides the Aquaport the helmet also has a frontal ventilation grid to draw air into the helmet. The integrated lens is also an integral part of the helmet and can be moved forward so that air can flow into the helmet when needed. This creates an airflow through the helmet with air passing over the rider’s head and out the two tail vents. A trip wire on the top of the surface of the Wasp creates micro vortices to assure for a smooth airflow over the tail of the helmet. The Lazer advanced Turnfit retention system makes sure the helmet is snug and comfortable on the head. - Superior aerodynamic performance - Water cooling system - Panoramic lens - Adjustable lens - Advanced Turnfit system - Closed Aquavent - Lazer LifeBEAM compatible - Lazer Inclination Sensor compatible - Fit System: ATS Advanced Turnfit System - Construction: In-Mold - Ventilation: 3 Vents + Aquavent - Weight: 375g (S) - Certification: CE-CPSC-AS

The most aero road helmet in the peloton now breathes better. The S-Works Evade 3 was reinvented from the inside out to cool better, making it the fastest choice for more stages. Through extensive Computational Fluid Dynamics and Win Tunnel testing, we created a rear "diffuser" that helps minimize drag and improve ventilation. The diffuser helps optimize aero performance by allowing air to release easier and improves ventilation by drawing 10% more air through the helmet at a given speed. The Occipital Base Adjustment optimizes comfort by personalizing fit to individual head shape and helmet angle can be adjusted for compatibility with glasses. An adjustable Tri-Fix web system gives riders added comfort with updated, thinner 10mm webbing that minimizes strap noise. And the ANGi-ready, ultralight Mindset micro-dial fit system with height adjustability has been updated for improved grip and reaction for easy on-the-go fit. Our ultralight and supremely comfortable MIPS Node Air technology is integrated directly into the helmet padding, with a sleek low friction layer designed to dissipate rotational forces. With Specialized's proprietary development work, we added perforations to maximize breathability, performance, comfort, and weight savings. - Enlarged front vents help increase ventilation. - Rear Diffuser for aero and ventilation benefits. - MIPS Air Node is MIPS' most ventilation-focused solution. - Adjustable Tri-Fix web splitter boosts comfort through personalized fit. - Precision, full-wrap polycarbonate shell for increased durability and premium finish. - Dual-density optimized EPS foam.

The S-Works Prevail 3 helmet is perfect for riders who value the comfort and thermoregulation benefits that superior ventilation delivers. It is the ultimate all-around helmet that excels in hot conditions, strenuous climbs, and mountainous stages. With a never-ending quest to push the limits of ventilation, we eliminated air-blocking foam "bridges" from the center, effectively creating thru-air channels that increase the surface area of ventilation by 24.5% compared to the S-Works Prevail II Vent helmet. The all-new S-Works Prevail 3 has the most ventilation area of any helmet we have ever made. When a helmet is impacted, its job is to dissipate the energy of the impact. The conventional approach to helmet design is that more foam (EPS) means better energy management. We re-wrote the book on cycling helmet design by innovating beyond foam. Woven aramid "cables" traverse the helmet and are anchored to carbon fiber side panels. Upon impact, the AirCage technology* works as a suspension bridge and is designed to distribute localized forces throughout the helmet. The Occipital Base Adjustment optimizes comfort by personalizing fit to individual head shape and helmet angle can be adjusted for compatibility with glasses. An adjustable Tri-Fix web system gives riders added comfort with updated, thinner 10mm webbing that minimizes strap noise.
