Description
The fastest wicking thermal baselayer on the market, tried and tested in some of the most extreme environments on the planet. The xerotherm is specified by the FBI and many other professional dive teams.
With flat seams and a long body to ensure that no separation between top and leggings develops, the top is the ideal next-to-skin layer under a drysuit. Thumb loops keep the sleeves in place whilst donning the drysuit and should be removed from the thumb and pushed back through the wrist seals prior to diving.
These simple, minimalist leggings have been designed for maximum performance. The high waistband ensures good overlap of the top and leggings and unique foot pocket design ensures the leggings do not ride up. Flat seams provide next-to-skin comfort throughout the dive.

Your drysuit doesn't keep you warm — this does

Frequently Asked Questions
Find answers to common questions about our gear, courses, and policies.
Which drysuits can I buy off the shelf?
The Avatar Airon and the Bare Aquatrek Evo are our off-the-shelf suits — you can be diving one straight away.
How long does a made-to-measure suit take?
It depends on the brand. Navyfel is about 4 weeks, Bare about 8, Santi 8 to 10, and Fourth Element around 16. If you have a trip booked, work backwards from that date and come and talk to us early.
Which drysuit should I go for?
It depends on the diving you want to do — cave, cold water and travel all pull in different directions on material, seals and pockets. Tell us what you want to use it for and we will tell you honestly which suit fits that.
Does the suit itself keep me warm?
No — the undergarment does. The suit is a shell that keeps water out; the loft underneath is what holds the heat. Getting that layer right matters as much as the suit, and bulkier is not automatically warmer.
