Aqua Sphere Men's Energize Compression Speed Suit - High-Performance Swimwear for Competitive Swimming & Triathlon Training

I’m 5’9, 137 lbs, 31” waist.I ordered a 30.It fits perfect.It doesn’t absorb any water. I swim 2k several times a week.It zips on the back so it’s helpful to have someone zip and lock.Very pleased with it and would definitely recommend it, especially at the price I paid.I'm very large for a tri competitor. At 6'2" and 200 lbs, it's tough to find gear that fits correctly. This is the most comfortable suit I've found by far without being baggy in the legs. My only complaint is the cryptic sizing chart w/ no translation. For reference, my chest is about 48, waist is 36. I bought size 38 US and it works for me.I'm 5' 10" tall, 31" waist, (40" chest). I ordered the 32" as per the sizing guide. It fits just fine in the waist, but is way too tight under the arms where my lat muscles are. There is no way I can move my arms in this size without getting cuts under my arms.Perfect fit! Size 30 (international sizing = xs) i stand 5'10", 31" waist. Just add a ribbon or leash on the zipper for easy removal. ;-)Fantastic speed suit. Size got true to sizing. Have worn in 3 races this season.Great Product
