Paragliding and Mountain Sports Sunglasses: Technical Guide
At altitude, the sun isn't the same as at sea level — there's more UV radiation, more glare off clouds and rock, and constant wind on your face. And in paragliding there's something else: if your glasses come off mid-flight, there's no getting them back. Here's what actually matters before buying paragliding or mountain sunglasses.
Why altitude changes what you need from your sunglasses
UV radiation increases with altitude — the higher you go, the less atmosphere filters the sun. Add glare from clouds, light-colored rock, and, in winter, snow, which multiplies the light hitting your eyes from every angle, not just head-on. Sunglasses built for everyday city use aren't ready for that combination.
What actually matters in paragliding and mountain sunglasses
1. Real UV protection, whatever the model
With more UV exposure at altitude, a tinted lens without real filtering isn't enough. The entire KOH range carries UV400 protection — the minimum baseline before looking at anything else.
2. A frame that holds up to impact and rock contact
On technical mountain terrain, brushing against rock or a fall shouldn't mean a scratched lens or a broken frame. KOH's flexible TR90 absorbs impact better than a rigid frame, without losing its fit or shape.
3. Secure fit — in paragliding there's no room for error
In hiking, losing your glasses is an annoyance. In paragliding, with constant wind on your face throughout the flight, it's a real risk of ending up without them mid-air. A lightweight frame with a real grip on the nose and temples is the first line of defense — and for flying, it's worth going one step further (see below).
4. Lightweight frame that won't weigh you down for hours
On a long hiking route or an extended flight, weight on your face starts to show after several hours. KOH's TR90 frame weighs 35g — built to be worn the whole session without marking or tiring.
Paragliding vs. hiking and trekking: same criteria, different risk
The technical base is the same in both cases — UV protection, a good fit, a lightweight frame — but the risk changes. In trekking, if your glasses fall, you pick them back up off the ground. In paragliding, if they come off mid-flight, they're gone. That's why many pilots use a retention cord or a floating strap like KOH's, compatible with the whole range thanks to the slim-fit design — not essential for a hike, but for flying it's the difference between a scare and a real loss.
Which KOH models work for paragliding and mountain sports
Within the extreme sports sunglasses collection, models like EAGLE, FALCON, or THUNDER give wraparound coverage and a wide field of view, key both in flight and on technical terrain. And if you're flying, pair any model with the KOH floating strap or the KOH Anchor — real insurance against losing them mid-flight.
Frequently asked questions
How do I avoid losing my glasses while paragliding?
With a well-fitted frame as the first line of defense, plus a floating strap or a retention clip like the KOH Anchor — if they come loose, they stay attached to your gear instead of falling.
Which frame holds up best to an impact on technical terrain?
KOH's flexible TR90 frame absorbs impacts and rock contact better than a rigid frame, without losing shape or fit.
Do the same glasses work for paragliding and hiking?
Yes, the technical base is the same. The real difference is the risk of loss — in flight, it's worth going one step further with an added retention system.
Are KOH sunglasses photochromic?
No, no model in the current catalog has a photochromic lens. UV400 protection is fixed across all models in the range.
Which frames hold up best for a full day of flying or hiking?
KOH's 35g TR90 frames are built for exactly that — lightweight, flexible, and with real grip at the contact points, so you don't notice them after hours of wear.
