Sven Can See is a Clever Anti-Fog Solution for Glasses and Goggles

For anyone who wears eyeglasses, fogged lenses can be a source of frustration. For the scuba diver or winter sports enthusiast, they can be a serious safety issue. And for the soldier, fire fighter, or first responder, lens fog can be a matter of life and death. In fact, I can’t think of a single situation, aside from a throwaway gag in a 1980s comedy, in which fogged-up glasses or goggles are ever desirable .

But how to combat lens fog? There’s the old spit and rub technique, but that usually has modest efficacy and requires saliva to be mere millimeters from your eyes. There are pricey anti-fog lenses that come pre-treated, but they won’t help your existing eyewear. You could simply wipe your glasses, goggles, or mask every time the surface fogs up, but that’s not ideal when you’re skiing down a double black diamond slope, a couple hundred feet under water, or engaged in active combat.

The best idea is to apply a few spritzes of Sven Can See anti-fog gel to your lenses, smear the stuff all over the glasses/goggles/mask, and then enjoy eight hours or more of anti-fog protection.

Allow me to share my personal experience with the brand. I attended an Outdoor Retailer event in New York City. I’d never heard of Sven Can See, which launched in 2015, and I can’t say I had ever given any thought to anti-fog products, annoying as lens fog can certainly be.

Sven Can See had a booth set up rather near the entrance; as I stood nearby, studying a display laden with hiking boots, a gentleman caught my ear and asked if he could introduce me to the brand. It turned out to be Scott Newman, the president of the company (which was named for a fictional character from a story he would tell his daughter) who had developed the solution after enduring the frustration of fogged-up eyewear during winter hikes in northern Maine.

Newman explained how the formula is made from natural ingredients and is 100 percent safe for regular use. It’s largely coconut-derived, I recall him saying, though the actual formula is kept secret. The ingredients list only “biodegradable surfactants”.

One application of Sven Can See usually lasts at least eight hours. For extreme wintry conditions, they also make an Anti-Fog/Frost Xtreme Cold Spray, and, for dirty lenses, they offer a lens cleaner. (Clean lenses subsequently treated with anti-fog spray resist fogging better, see?)

Thus far I’ve primarily used Sven Can See on the sunglasses I wear while running or hiking, and no fog yet, baby. As the temperature drops, I’ll continue applying it to my glasses and will ideally hit the slopes.

The Pebble Flow travel trailer is packed with tech and ready to change vanlife forever
The future of RV'ing is bright, tech-forward, and all-electric for serious on- and off-grid camping.

It seems clear that the future of the world's vehicles is electric. As it turns out, running all our cars and pickups on dead dinosaur juice is only going to take us so far—literally. And the battery-powered revolution has begun in the RV industry, too, thanks in large part to the official drop of the all-electric Pebble Flow travel trailer.
California-based Pebble first announced its electric travel trailer back in 2023. Based on the long list of next-gen features and specs, I was stoked—tentatively, though, as vehicle manufacturers have a history of overpromising and underdelivering when it comes to concept announcements. I'm happy to report that the company has begun delivering its Flow Founders Edition, and everything we loved about the original seems to have come to fruition.

It's a 100% electric RV designed to move seamlessly between on- and off-grid camping, making it the perfect go-anywhere live/work/play space for modern nomads. Pebble promises up to seven days of off-grid camping, including full use of all onboard appliances. This is no small feat. RV owners who've tried to venture too far from the frontcountry know the struggle of keeping cool in the summer with a beastly, power-hungry air conditioner. But, it appears Pebble has finally solved this problem.
It's clear that Pebble put just as much thought into the interior design as well. The furniture is not only sleek, modern, and handsome, but the living quarters easily transform between office, bedroom, and lounge as needed. Panoramic windows with one-touch instant privacy glass envelop the space, creating a vibe that's bright, airy, and breezy. Tasteful ambient lighting and high-end finishes throughout elevate the look and feel well above the bargain basement vibe found in most "ordinary" RVs.

Wildfire forces closure of Grand Canyon’s North Rim for the season—and maybe longer
Grand Canyon National Park faces massive closures due to natural disaster
A sweeping view of Grand Canyon on a winter morning

The Grand Canyon is one of the many areas currently affected by the Dragon Bravo Wildfire, which began last month. According to AZ Central, officials speculate that the fire began due to a lightning strike, which then spread rapidly due to sustained winds of 20 miles per hour, with gusts reaching up to 40 miles per hour. As of July 27th, 2025, the fire was still active, and the National Park Service reports that somewhere between 50 and 80 structures have been lost, including many administrative buildings and visitor facilities. Fortunately, they also report that no one has been injured, and no loss of life has been reported. Unfortunately, this devastating fire has closed the North Rim for the remainder of the season, and possibly longer.

Torsus Praetorian Liberra is a luxe motorhome disguised as a rugged, off-road RV
Go-anywhere capability meets high-end studio apartment luxury in an impossibly over-the-top design.
A Torsus Praetorian Liberra off-road RV parked in a desolate landscape.

In the world of driveable RVs, the largest rigs (think over-the-top, Taylor Swift tour-worthy motorhomes with all the fixin's) typically trade off-road capability for luxury. Of course, longer wheelbases, high-clearance roofs, and insanely heavy curb weights just aren't conducive to off-roading because, well, physics. But for those who refuse to compromise, there's the all-new, all-absurd Torsus Praetorian Liberra.
Everything we know about the Torsus Praetorian Liberra off-road RV

On the outside, the Torsus Praetorian Liberra exudes "Martian tour shuttle bus" vibes with the sort of straightforward, all-business silhouette found on personnel-carrying trucks and transport vans. But the upgraded ground clearance, chunky, oversized tires, and high-intensity light arrays hint at something more at play. German builder Dämmler bills the original Torsus Praetorian as "a vehicle that deliberately finds its territory off the beaten track. Whether it's transporting miners through open-cast mines, tourists to volcanoes, or military operations, the Praetorian knows its job." In its base trim, it's not designed as a chariot for uber-wealthy overlanders. But Dämmler sought to expand the vehicle's initial intent with the all-new Liberra model: "A perfect companion for discovering the world, the Liberra combines it into a new type of motorhome." This is a go-anywhere rig designed to take you from A to B ... to Z, and everywhere in between in style.
The Liberra shares the same underpinnings as the OG Torsus Praetorian, including a MAN TGM chassis and a beefy, six-cylinder diesel that pushes power to all four tires. With a 27.5-inch (70 cm) ground clearance, it's more than capable of fording rivers and driving over just about anything you need it to. Rounding out its off-road-centric design are three differential locks and an integrated cable winch, in case your off-roading goes a little more "off" than you were expecting. It's all wrapped in an ultra-durable GRP skin with a mil-spec external finish.
But what separates the Liberra model from its predecessor is the interior. Every last fixture, feature, and piece of furniture has been swapped out to create a rolling luxury studio apartment. The rear sleeping quarters are available in one of two configurations: A pair of beds designed to sleep up to four adults or a single, larger bed that's perfect for couples sans children. Beyond that, both configurations include a generous, full-featured wet bath, tons of storage, and a kitchenette. Extensive wood detailing, tasteful accent lighting, and a high-end fit and finish throughout elevates the interior well above what we've come to expect from "ordinary" RVs.
