GUB 6300 Rimless Photochromic Cycling Glasses with UV400 PC Shield Lens, Adjustable Nose Pads and Prescription Insert Frame for Road and Mountain Bikes

Photochromic shield lens for changing light

The GUB 6300 uses a single-piece photochromic shield lens that becomes darker in stronger outdoor light and remains lighter under lower-light conditions. The tint response helps one pair cover varied daytime riding environments without requiring a manual lens swap.

Rimless wide-view cycling design

The rimless lower edge keeps the field of view open while the broad wraparound lens adds coverage around the eyes. The shape is intended for road cycling, mountain biking and other outdoor activities where forward and peripheral visibility matter.

UV400 PC lens and lightweight frame

The source identifies a UV400 polycarbonate lens and a PC frame. The complete glasses have a listed net weight of approximately 25 g, reducing carried weight while retaining a full shield-style lens and stable temple arms.

Adjustable soft nose pads

Flexible nose pads can be positioned for a more secure fit and improved lens clearance. Adjust both sides evenly and avoid excessive bending. Fit depends on individual facial shape and helmet position.

Prescription insert frame included

A removable prescription insert frame is included behind the shield lens. Corrective lenses are not included and should be fitted by a qualified optical provider according to the insert dimensions and the wearer's prescription requirements.

Dimensions and included accessories

The source lists an overall width of approximately 146 mm, lens height 73 mm, lens width 60 mm, bridge width 25 mm and temple length 129 mm. The photographed package includes the glasses, prescription insert frame, soft pouch and protective hard case.
