The Bibjohn is 5mm thick from the oval ankle openings up to the crotch and up the sides of the hips. From that seam up, the Bibjohn is 2mm thick. This includes the midsection around the stomach, low back, as well as the bib straps that extent up the spine in back and up the chest in front. It is designed this way so when you wear any of our T1 tops, the total rubber thickness remains less than 5mm thick. You have all the needed flexibility while still keeping your spine and vital organs warm. The total thickness also adheres to all rulings from all national and international governing organizations that limit the maximum wetsuit thickness to 5mm.
Whether you like to swim for exercise or are on the swim course of a Triathlon, T1 Wetsuits offer you speed, comfort and buoyancy that will make swimming pure pleasure!
