Metalux Temperate 100g Undersuit


The Metalux® Temperate 100g is most commonly used for UK summer diving conditions. When worn with a drysuit with thermal properties, it's also a good match for colder conditions. For extra thermal protection, take a look at the Metalux® Arctic 200g and Arctic 300g. Metalux® is one of the most lightweight, high-performance insulating materials available, which works by reflecting thermal radiation and reducing air movement. Its thermal performance is retained for the life of the undersuit, and...

Toasty Warm

By Barry Francis on 17 Aug. 2015

Having owned a previous under suit by ND and now owning another drysuit, I thought I would treat myself to a new undersuit as the old one was too small. I really feel the cold when diving but wearing this suit I feel so comfortable here in the UK - even at the beginning of the season when sea temperatures are a cool 7-9 degrees .... I didnt feel cold at all even after a 40 minute dive! What a way to stay warm ! Great suit!

Warm, Non-Restrictive, Comfortable Undersuit

By Anonymous Customer on 23 Apr. 2014

Well, I have been using this undersuit now for the past year, and I must say that it kept me warm in water as cool as 8 degrees. Now the water is a rather warm 15 - 18 degrees I find that the undersuit leaves me sweating during and after a dive. I wear this with my Neoprene Northern Diver Divemaster Drysuit, and I must say it has been the best buy I have done following a rather chilled dive in a tri-laminate suit. I have never been cold since..

Fantastic Undersuit

By Trev Ridgway on 11 Sep. 2014

I bought a Northern Diver Metalux Temperate Undersuit in December, to use under my membrane drysuit. With the thought that this would do me for both winter and summer, donning additional layers in winter. How wrong.. Having dived in the resent cold snap, using the Metalux, I found that I was so warm during the first dive that I removed my base layer for the the other dives. Even standing around between dives, I found that I was still ok. I think Northern Diver have a winner with the Metalux Temperate, it is a fantastic product. My thanks to AL Wright for the help and advice he gave me. Fantastic Customer Service, without a doubt.

Warm as a Warm Thing on a Warm Day

By Daryl Townsend - Flood Team on 05 Dec. 2015

We trained as Water Rescue Technicians mid Jan 2012. Although we thought we had good undersuits, boy were we wrong.... Numb leg, frozen feet etc... This year we had the Northern Diver Metalux Temperate undersuit and I could actually feel my legs at the end of a long day in the north Wales water. 1 degree C temp, at best and I was almost sweating... The suits are fantastic. Many thanks to Craig and the Northern Diver team.

Almost too warm

By Luke on 07 Feb. 2014

I have just started using the new style of 100gsm metalux undersuit, having been using the old style of the same weight, under my ND Divemaster drysuit for about 18 months in all condtions, and the difference is huge. The design and manufacture guys at ND have really done us proud on this one. Compared to the old style with the stretchy joints, this has none of the thinner patches for articulation, but it is better cut and more comfortable without being restrictive. The outer of the suit, rather than being quilted is made from continuous panels. As soon as you step into this suit, you notice that you are going to be warm. In the water the undersuit feels good, and retains a good thickness of insulation around you, and again, there is no noticeable restriction in movement. In 11 degrees, I usually throw on a base layer underneath my undersuit, just to take any chance of a chill off later in the dive, in the new Metalux, well, lets just say, due to being properly warm, I lost the base layer after the first dive. Later in the day on another dive I found myself leaving the undersuit slightly unzipped to get a little cooling! I am now looking forward to the winter again, so I can really put this undersuit to the test. But for now it gets a solid 10/10 in my book, just a shame the weather has cheered up and the water is getting too warm to use it..!
