Description

Without question one of the most popular drysuit undergarments on the market, the two-piece Arctic undersuit is suitable for use on its own underneath neoprene drysuits or in a layering system with base layers under a trilaminate suit. Low bulk, high insulation, the high density fabrics maximise thermal protection whilst wicking away moisture from perspiration and suit leaks.

The Arctic top is designed with a long body portion to ensure adequate overlap between the top and trousers. Thumb loops prevent the sleeves from riding up during donning (remember to remove them and tuck them back underneath the wrist seals after donning). Tuck the top into the waistband of the trousers before donning drysuit to prevent any separation during the dive.

The Arctic leggings feature secure foot loops to keep leggings in place when donning the drysuit. A high waistband ensures that separation of top and leggings is minimised. Tuck the top into the waistband before donning the drysuit. The lower legs are single layered to prevent too much bulk around the ankles, making donning easier. Short and regular leg lengths are available.

The Arctic undersuit is complemented by the Arctic socks, which completes the thermal protection system, offering low bulk thermal protection to the extremities. The two layer construction is warm and comfortable, and the inner liner can be pulled out from the outer liner to speed drying times.

Fourth Element Arctic Undergarment

Your drysuit doesn't keep you warm — this does

A drysuit is a shell. What keeps you warm is the loft underneath it, and getting that layer right is the difference between enjoying a winter dive and counting down the minutes.

We stock the Santi and Fourth Element ranges we dive ourselves, from merino base layers through to heated systems for long decompression and rebreather dives. Thicker is not automatically better — an undergarment that's too bulky compresses, kills your fit and drives your weighting up.

Come in with your suit and we'll match it properly. It's a five-minute conversation that saves a lot of cold diving.

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.
