K2 Source Goggles

Lens swapping

Thumbnail-size connection points are easy to handle with gloves on: Flick them open and switch between the dark emerald- and light amber-tinted lenses.

Case

Skier’s conundrum: Do you tote spare lenses in a heavy, brick-size hard case or a soft sleeve that leaves them vulnerable to damage? Enter the Source’s included case: It has a hard shield to protect lenses, but packs down flat. “Finally, a case I actually take with me into the backcountry,” one tester says. We liked stowing it in our thigh pockets for easy access.

Fit

Enjoy massive field of vision with the oversized lenses. Folks with smaller faces felt pressure on their nose bridges, though.
