FULL-FACE CYCLING HELMET FOX PROFRAME RS HEATSTACK

Fox Proframe RS Heatstack full-face MTB helmet

Fox Proframe RS Heatstack is a premium lightweight full-face MTB helmet, designed for enduro, trail, and downhill riding, where you want maximum protection without the feel of a heavy DH helmet. It combines the advanced Mips® Integra Split system, precise BOA® fit, efficient ventilation, and a premium Ionic+ interior in a construction certified to the ASTM-F1952 downhill standard.

Mips® Integra Split for advanced protection

The Mips® Integra Split system combines two different protective layers and an intermediate low-friction layer. The construction is designed to help reduce rotational forces in certain impacts while more effectively managing energy at different impact speeds.

BOA® Fit System for precise fit

The BOA® system enables very precise micro-adjustments to the fit even while wearing the helmet. By turning the dial you can quickly loosen or tighten the system, and the four-position adjustable rear cradle allows further adjustment of the helmet’s position on your head.

Lightweight full-face feel with effective cooling

Proframe RS is designed to reduce the contact surface with the head and increase airflow through the helmet. The result is better cooling on climbs, transfers, and long enduro stages, without sacrificing the protection of a full-face construction.

Ionic+ interior and adjustable cheek pads

The antimicrobial Ionic+ liner helps wick moisture and control unpleasant odors. The set includes two pairs of cheek pads: the thinner ones are installed as standard, while the thicker ones allow a tighter and more secure fit.

FIDLOCK® and 3-position visor

The FIDLOCK® magnetic closure allows quick and easy opening and closing even with gloves. The visor is adjustable to three positions and compatible with MTB goggles, and there is a removable GoPro® mount located under the visor.
