Smith Mono Lake vs. Lowdown XL 2 vs. Riptide: Which Smith Sunglasses Are Right for You?
Choosing between Smith's lifestyle and active sunglasses comes down to fit, coverage, and how you'll use them. The Mono Lake, Lowdown XL 2, and Riptide all feature ChromaPop lenses and prescription-ready frames, but each serves a different purpose.
Mono Lake: Retro Aviator for Everyday Versatility
The Mono Lake is a 1991 Archive reissue with a 6-base aviator shape, large coverage, and a modest wraparound fit. It's built for people who want one pair that works everywhere—driving, hiking, beach days, road trips. The medium fit suits medium to large faces, and the adjustable nose bridge lets you dial in comfort. Outside Online called it their favorite everyday sunglasses after testing two dozen pairs, praising its stay-put feel and glare-busting optics. If you want distinctive retro style with modern lens tech, the Mono Lake delivers.
Lowdown XL 2: Casual Rectangular for Daily Wear
The Lowdown XL 2 takes a different approach with a flatter 4-base rectangular lens curve and a lower-profile design. It's more casual and urban-focused, with a shape that works under helmets and in everyday settings where you don't need maximum sun coverage. The XL version fits larger faces, and the 4-base curve accepts a wider range of prescriptions than the Mono Lake's 6-base. Starting at $149, it's also slightly more affordable. Choose the Lowdown XL 2 if you prefer understated rectangular styling over the Mono Lake's bold aviator look.
Riptide: Performance Frames for Active Days
The Riptide is Smith's performance option, with spring hinges that expand at the temples for a snug, flexible fit during runs, bike rides, and high-movement activities. It's available with ChromaPop Glass lenses for superior scratch resistance—ideal if you're hard on your gear. Italian-made frames and a focus on athletic performance make the Riptide the choice for serious outdoor athletes. The trade-off? A higher price (up to $307) and styling that's more sport-focused than the Mono Lake's versatile everyday vibe.
The Verdict
Pick the Mono Lake if you want retro aviator style, large sun coverage, and a frame that handles everything from the beach to the ski hill. Choose the Lowdown XL 2 for a lower-profile rectangular shape that's more casual and prescription-friendly. Go with the Riptide if you need performance features like spring hinges and scratch-resistant glass lenses for active pursuits. All three offer ChromaPop clarity and prescription compatibility—it's just a matter of fit, style, and how hard you'll push them.
