For centuries swimming pools have been one of the best ways to make neighbours jealous—second only to ride-on lawnmowers and chocolate-sauce moats. Keep up with the underwater Joneses with today’s Groupon: for $20, you get $40 worth of swimwear and accessories at Ly Sports on Wyandotte Street East.

Ly Sports supplies the duds for poolside catwalks with swimwear and accessories from name brands that include Speedo, Durafast, and Endurance. Snorkelers can keep up with underwater acquaintances or turn co-worker's heads at the office with adjustable dive fins by Speedo ($39.99) or intimidate swim meet competition while sporting a pair of Speed Socket goggles ($31.99), a silicone-strapped competition goggle that can be custom-fitted with the help of knowledgeable staff. Ly Sports also stocks swim apparel for the competitive backstroker and the casual toe-dipper alike, with versatile swimwear selections that include 100 per cent chlorine resistant Endurance Jammer swimsuits ($49.99). Customers can also slip into a women’s Endurance Splitsville one-piece suit ($74.99), which is composed of a special Endurance Lite fabric designed to channel water and reduce drag, leading to swifter swimming during triathlons and bathtub duckie rescue missions.
