Ventilated bicycle helmet with magnetic visor

This GUB cycling helmet combines a vented PC outer shell and EPS foam structure with a detachable magnetic photochromic visor. Choose the verified color and M or L fit range shown in the option label. The visor is supplied with each listed option and can be removed or placed in the raised position demonstrated by the source.

Photochromic visor and three-point attachment

The clear-to-darker photochromic visor changes its appearance with exposure conditions, as shown by the supplier comparison images. Three magnetic attachment points locate the visor on the helmet. The large visor is demonstrated with prescription glasses underneath; actual eyewear clearance depends on frame size and individual fit.

PC shell, EPS structure and ventilation

The detail specification identifies a PC shell and EPS foam construction with 21 ventilation openings. The source close-ups show the shell edge, internal channels and vent arrangement. The shaped liner pads can be removed, and the side sections are thinned in the illustrated construction to accommodate the stated head shape.

Fit adjustment, straps and removable pads

A rear adjustment dial changes the retention fit, while the strap buckle and side strap junctions position the chin straps. The source identifies an ITW buckle and shows the retention cradle, removable padding and buckle detail. Select the correct size first and adjust the retention system and straps to suit the wearer.
