Review on Water Gear Swim Cap - Synthetic Fiber, Comfortable & Durable for Short or Long Hair, Keeps Hair Dry in Competitive & Recreational Pool Time - One Size Fits Adults, Men, Women & Kids by Jim Bijelic

I LOVE IT. LOVE IT. 10 stars. I've always had "compression headaches" from Speedo Lycra baseball caps. I am a bald man with a medium sized head. Did I mention I have no hair? The speedometer cover is 25 1/8" in circumference while the water gear is 29 7/8" in circumference. Diameter at Speedo rubber band = 8.0 inches. Water mechanism cover = 9.5 inches. It fits my head perfectly. NO HEADACHE COMPRESSION. In addition to my hat, I wear a neoprene ear-band-it around my forehead and ears to keep the headphones securely in place while swimming. First I bought a neon orange cap to try. Today after the swim I will order a few more caps in different colors. Hope it works for you too. bald guy
