Ranked #4 in Best Sunglasses For Running

Julbo Ultimate Reactiv

4.5

1 sourceall derived$254.95as of Oct 16

The Julbo Ultimate is a wraparound sport sunglass with a single panoramic Trivex lens, available with Julbo's REACTIV photochromic lenses. Engearment wore the REACTIV 1-3 high contrast version Nordic skiing and mountain biking and made it its new go-to for changing light: the lens adapts very rapidly across a 13% to 72% light transmission range, and the moldable CustomFIT temples and shapeable 3D nose pads give a snug fit it barely felt. It is the most expensive pair on this page.

Strengths

— REACTIV photochromic lens adapts very rapidly to changing light, per Engearment
— Wide light transmission range, 13% to 72%, per Engearment
— Pliable CustomFIT temples hold the shape they are molded to, and Engearment got no hot spots or headaches over hours of exercise

Watch-outs

— Engearment could sense the outside and bottom edges of the lens in its peripheral vision

SunGod Ultras Air

4.7

1 source$205as of Oct 11

The SunGod Ultras Air is an ultralight option at 24.5g, featuring Grip-Lock hydrophilic nose pads that secure the fit during heavy sweating by increasing friction as moisture rises. The frameless design and 8KO spherical lenses provide optical clarity without fogging, while construction from recycled materials supports sustainable cycling values. However, the compact shape may feel too restrictive for runners with larger heads, and some users report that the nose pads become pinchy on broader noses after extended wear. This model fits athletes prioritizing minimal weight and secure grip in hot conditions, but those with wider facial structures or sensitive nasal bridges should look elsewhere.

Strengths

— Weighs only 24.5g, making it the brand's lightest frame to date and nearly unnoticeable on the face.
— Features Grip-Lock hydrophilic nose pads that increase grip as sweat rises to prevent slipping during high-intensity runs.
— Utilizes 8KO spherical lens technology for optical clarity in changing light conditions without fogging up.

Watch-outs

— The compact, closer-fitting shape may feel too small or restrictive for runners with larger heads compared to the original Ultras model.
— Some reviewers noted that the nose pads can be pinchy on broader noses after extended wear.

How they stack up

Julbo Ultimate Reactiv

The only photochromic lens on this page: the Goodr OG uses a fixed polarized lens. At $254.95 on Julbo's US store it costs more than the Ombraz Refugio ($195) and the SunGod Ultras Air ($205), and about ten times the $24 Goodr OG.

SunGod Ultras Air

At just 24.5g, SunGod Ultras Air is significantly lighter than the Julbo Ultimate Reactiv and Ombraz Refugio, making it nearly unnoticeable on the face. Its Grip-Lock hydrophilic nose pads increase friction as sweat rises, offering a different anti-slip mechanism compared to the special grip coating on Goodr OG.
