Drysuit Undersuits, Undervests & Garments

The Apeks ThermiQ Carbon Core sets new standards in base layer thermal protection. Comfort is guaranteed thanks to its triple layer softshell – which keeps you comfortably warm in all environments – as well as its technically advanced graphene lining, which acts as a superconductor – regulating skin temperature by transferring heat from warm spots to cold spots on the body – to provide the ultimate level of warmth and flexibility. 

The ThermiQ Carbon Core can be worn on its own as a thermal rash guard in warm water or as an extra layer underneath a drysuit. Mostly because its breathable fabrics prevent moisture from building up when used underneath a drysuit, whilst its elasticated thumb loops keep the top in place when worn beneath a drysuit. 

A warming undersuit that will keep you comfortable and protected as you explore the expansive world beneath the waters. The combination of the No-Zip technology and the wicking materials, make the ThermiQ Base by Apeks a pleasure to dive in— offering freedom of movement and essential warmth.

Aqualung’s 2mm hooded undervest offers comfort and durability all rolled into one fantastic item! Made from super-stretchy neoprene, this undervest permits for full-range of motion when worn, and is easy to don or doff. Thanks to its 2mm thickness, your core is kept comfortably warm and protected, and this feature is supplemented by strong, long-lasting seams which are glued and blind-stitched to keep the water out.

Finally, the edges are made using binding tape for a neat and non-fraying look that lends this practical undervest an appealingly stylish aesthetic. Wear it on its own or under your hood-less drysuit for enhanced warmth and comfort.
