Metalux® Undersuit (100g, 200g, 300g)

Description

Metalux® is a unique undersuit material. Northern Diver designed Metalux® to be one of the most lightweight, high-performance and high spec, insulating materials available. We've designed our Metalux® range to be suitable for use in conjunction with all our neoprene and membrane drysuits.

Why does Metalux® have such an enviable reputation?

We're proud to say it's one of the most effective insulative materials available. We've developed these undersuits to insulate and reflect a diver's own body heat back to them. This thermal radiation is combined with reducing air movement through our design to further help the dive retain warmth.

Our Metalux® range retains these impressive insulating qualities whether dry, wet or compressed. The quilted construction means that the undersuits' thermal performance and integrity is retained throughout the life of the garment.

Metalux® undersuits are durable, hard wearing and machine washable.

The flexible panels on the lower back, shoulders, cuffs and feet of each Metalux® undersuit provide exceptional freedom of movement, without sacrificing warmth. We fleece-line the inside of our Metalux® undersuits for comfort and further, added warmth. For your convenience, there's pockets on the thighs and a zipped left chest pocket. We've also developed them to be bacteria and fungus resistant. Not only are Metalux® undersuits machine washable, they'll withstand multiple washes.

What is each Metalux® undersuit designed for?

We class our Metalux® 100g as a temperate undersuit. It's most commonly used for UK Summer diving conditions. We'd only suggest wearing it in colder conditions when worn with a drysuit with thermal properties.

If you feel the cold more or need an undersuit that provides extra thermal protection, we'd suggest you take a look at the Metalux® Arctic 200g and Arctic 300g.

The 200g Metalux® variant is, like the 300g, designed for cold to very cold conditions. It's the intermediate weight and tog in our Metalux® range, sitting between the Arctic 300g and the Temperate 100g. Choosing this undersuit rather than the lighter or heavier models is a personal preference. However, we would advise that it depends on your personal thermal requirements, whether your drysuit offers insulation and if you choose to wear your Metalux® undersuit with other thermal protection.

Our thickest undersuit in the Metalux® family is the Arctic 300g. It's designed for and suited to more extreme diving conditions, although we also recommend it for use with drysuits that don't have thermal properties; like Membrane and Tri-laminate drysuits.

How do I wash my Metalux Undersuit?

Our Metalux Arctic and Temperate undersuits (as with our Thermicore and Thermalux undersuit) have been specifically designed to be machine washable. We advise you select a cool wash (no higher than a 40° wash) and don't add any fabric conditioner - or other additives - just use standard washing detergent. The only other guide is that the undersuit must be allowed to dry naturally not tumble or machine dried. Once fully dry, the undersuit can be hung on a garment hanger or simply stored in a dry environment, away from direct sunlight or any other heat sources.
