It’s been a little over a year since Form released its second-generation smart swim goggles into the world. Since then, the company has been working on a way to ensure its headgear is even more attractive to swimmers who like to get out in the rough. Today, it’s announcing the Smart Swim 2 Pro, a modest upgrade on its predecessor with a focus on durability.

The 2 Pro’s lenses are now made of Gorilla Glass 3, which adds a gram or two more weight but should keep them scratch-free for far longer. Given the amount of open-water swimmers that use Form’s goggles, having faith that your lenses can take nature’s elbows is probably worth it.

If you’ve ever used a pair of regular goggles for a long time, you might notice how the anti-fog coating starts to wear off. Especially if you, like me, absentmindedly commit the sin of wiping the inside of their goggles with a finger when your view is obscured. Form may be proud of its current anti-fog coating, but realized there was a better way to keep the lenses clear for longer.

Consequently, the 2 Pro comes with a bottle of anti-fog spray that users need to apply before a swim. This isn’t a way of squeezing more cash out of the user base, however, as the company is proud to admit it’s just baby shampoo diluted with water. But Form has tested the correct ratio for optimal application and there are markings on the bottle showing you what you need to refill.

At the same time, Form is rolling out new features for its premium subscribers, including more data-driven program planning and more tips on where you need to improve. The company also revealed that its premium features are paying off, with swimmers seeing 1.4 times the gains in speed compared to the users who use the hardware alone.

The Form Smart Swim 2 Pro is available to buy July 15 for $329 in the US, $449 in Canada and €329 in Europe.
