Fourth Element Wetsuits are amongst the warmest and stylish wetsuits we offer at The Scuba Doctor. Fourth Element made their name designing undersuits for drysuit diving so they know their way when it comes to thermal protection for divers! The Proteus range of wetsuits has certainly cemented their position as a premium dive wetsuit manufacturer.
The Proteus has an internal bib on the 3mm, 5mm and 7mm which in effect gives you an additional 2mm thickness on any of the suits. The internal bib also stops the initial flush of cold water down your back when you jump in for that first dive! Although please note that the Proteus is what's called an athletic v-shaped designed wetsuit which in layman terms means a tight-fitting suit — so we have had people go up one possibly two sizes even when using the Fourth Element Wetsuit size chart.
