SunGod Ultras Air 8KO Sunglasses Review 2026
SunGod is a direct-to-consumer British brand that’s built a strong following among cyclists and triathletes for lightweight, customisable sunglasses with a lifetime warranty — and the Ultras Air, fitted with SunGod’s 8KO photochromic Iris lens, is the pick for anyone who wants one pair of glasses to handle both bright summer training and duller early-morning starts.
Key Specs
- Weight — SunGod’s Ultras frame sits among the lightest in its range, built for all-day comfort on long rides and runs
- Lens — 8KO technology: 2mm nylon rather than standard polycarbonate, which SunGod says gives sharper optical clarity and less distortion at the lens edges
- Photochromic — the Iris lens automatically adjusts tint as light conditions change, so you don’t need to swap lenses between an overcast warm-up and full sun later in a session
- Coatings — hydroleophobic coating to shed sweat and rain, plus triple-layer scratch resistance
Why It Matters for Triathletes
A photochromic lens is genuinely useful across a triathlon training week rather than a gimmick — a dawn open-water swim session, a midday turbo ride and an evening run all present different light conditions, and one pair that adapts means one less thing to pack. The deep lens shape (SunGod design their lenses to sit close to the face across their full width) also gives good peripheral vision, which matters in a bike pack or on technical descents.
Buying Tips
- SunGod sells direct and lets you customise frame and lens colour combinations on their own site — the version stocked on Tredz is a fixed colourway, useful if you want to buy through an existing account or bundle with other kit
- SunGod backs all its glasses with a lifetime warranty against breakage, which is worth factoring into the price versus a cheaper pair you’ll replace after a crash
- If you wear prescription lenses, check SunGod’s own site for prescription insert compatibility before buying — this isn’t offered through the Tredz listing
Care and Maintenance
Rinse with fresh water after every open-water swim or sweaty session to stop salt and sweat degrading the lens coating, and store in a hard case rather than a jersey pocket to avoid scratches from grit or keys.
