The Waterproof Body 2X Base Layer is an ultra-heavyweight, high-performance thermal insulation garment engineered specifically for extreme cold-water and technical drysuit diving. Fabricated from an exceptional 665g/m2 PowerStretch hollow-fiber matrix, Body 2X delivers maximum sub-surface thermal protection without creating rigid bulk. Inspired by the adaptive fur structure of the polar bear, its specialized filaments trap vast internal air reservoirs to combat severe deep-water hydro-compression. Available as individual tops and trousers, this premium modular system features elite moisture-wicking capillary action, integrated limb anchors, and factory-prepared p-valve access lines, providing a critical defensive foundation for extended exposure profiles. Technical Base Layer Features 665g/m2 Ultra-Heavyweight Insulation: Premium, high-density fabric weight engineered for freezing environments, offering more than double the thermal capture capacity of standard base layers Biomimetic Hollow-Fiber Technology: Advanced filament weave centers a permanent air bubble inside each thread to deliver ultimate thermal retention under direct compression at depth Independent Modular Sizing System: Separated top and trousers layout allows divers to independently customize sizing parameters or mix fabric weights across core muscle groups Capillary Moisture-Wicking Grid: Advanced technical fabric pulls metabolic sweat immediately away from the skin, moving it to the exterior surface for quick evaporation to block post-dive damp-chill ASTM D 3512 Grade 4.0 Anti-Pilling: Hardcore exterior jersey face independently verified to resist friction fuzzing and piling from heavy internal drysuit materials Pre-Routed Pee-Valve Integration: Factory-prepared pass-through pathways allow effortless, seamless routing for standard external catheter and P-valve hose configurations Secure Thumb-Loops & Foot Straps: Low-profile thumb loops and wide elastic ankle anchors lock the sleeves and pant legs perfectly in position, preventing bunching during tight drysuit entry Slim Drawcord Adjustable Waist: Tapered, low-bulk waist paneling features an integrated adjustment cord for a secure, flush fit beneath high-loft mid-layers Gender-Specific Tailored Paneling: Anatomically mapped structural cuts accommodate distinct physiological profiles, optimizing next-to-skin surface contact and comfort Technical Specifications Technical Parameter Material & Construction Standard Garment Packaging Standard Modular Custom Matrix (Top & Trousers Sold Separately) Fabric Weight Density Extreme Heavyweight: 665 g/m2 (Body 2X Specification) Material Composition PowerStretch Hollow-Fiber (90% Polyester / 10% Elastane) Anti-Pilling Rating ASTM D 3512 - Grade 4.0 Verification Hardware Integration Pee Hose Prepared Ports / Slim Waist Cord / Elastic Anchors Environmental Consideration 100% Plastic-Free Ocean-Safe Packaging apex Technology 665G/M2 BIOMIMETIC POLAR HOLLOW-FILAMENT MATRIX Standard undergarments rely entirely on the spaces between yarn strands to retain air. However, under direct drysuit squeeze or intense hydrostatic pressure, these spaces collapse flat, triggering an immediate drop in core body temperature. The Body 2X addresses this with an ultra-dense 665g/m2 hollow-filament polyester weave inspired by polar bear fur. By anchoring a permanent, sealed air micro-cell directly inside each individual fiber, the fabric secures an uncrushable thermal airspace that preserves core warmth through long technical sub-surface exposures. CAPILLARY ADVANCED WICKING ARCHITECTURE Physical exertion during equipment configuration or pre-dive surface transits rapidly generates sweat. If this moisture is permitted to pool against the skin under water, it forms a high-velocity thermal bridge that draws body heat away twenty-five times faster than dry air. The deep knit design of the Body 2X relies on capillary pressure to immediately lift perspiration away from the skin. It pumps fluid molecules outward to the exterior jersey face where they disperse cleanly, keeping the diver's skin dry and warm throughout the descent. TECHNICAL EXTREMITY UTILITY MATRIX Because technical diving demands absolute gear integration, the Body 2X completely abandons standard apparel cuts in favor of low-bulk utility sculpting. The separate top and trousers configuration allows for customized structural pairings, finished with smooth flatlock lines that prevent seam chafing. Outfitted with factory-routed p-valve exit tracts on both thighs and secure elastic thumb and ankle anchors, it interfaces cleanly with heavy primary undergarments and advanced commercial dive configurations without shifting.

The Waterproof Body X Base Layer is a high-performance, modular thermal insulation system engineered for technical and cold-water drysuit diving. Crafted from a premium PowerStretch hollow-fiber matrix, Body X mimics the structural evolution of polar bear fur to deliver an exceptional warmth-to-weight ratio. Available as individual tops and trousers, this fully customizable system allows divers to mix and match sizes and weights to perfectly balance localized metabolic heat requirements. With its advanced moisture-wicking capillary action, integrated thumb loops, foot straps, and pre-routed utility paths, the Body X stands as an elite foundational defense against sub-surface thermal loss. Technical Base Layer Features Biomimetic Hollow-Fiber Polyester: Advanced filament structure traps an internal micro-cushion of air within each fiber, maximizing thermal capture without increasing garment bulk Independent Modular Sizing System: Separated top and trousers layout allows divers to choose distinct sizing profiles and insulation densities for the upper and lower body Capillary Moisture-Wicking Grid: Technical weave pulls metabolic sweat quickly away from the skin, driving moisture to the exterior surface for rapid evaporation to prevent post-dive damp-chill ASTM D 3512 Grade 4.0 Anti-Pilling: High-grade structural face verified by rigorous testing standards to resist friction fuzzing and wear from drysuit internal linings Pre-Routed Pee-Valve Integration: Factory-prepared channeling pathways enable seamless routing for external catheter and P-valve hose setups Secure Thumb-Loops & Foot Straps: Low-profile thumb loops and wide elastic ankle anchors hold the sleeves and pant legs perfectly in position, preventing bunching during drysuit entry Slim Drawcord Adjustable Waist: Tailored, low-bulk waist paneling features an integrated adjustment cord for a secure, flush fit beneath high-loft mid-layers Gender-Specific Tailored Paneling: Anatomically mapped structural cuts accommodate distinct physiological profiles, optimizing next-to-skin surface contact and comfort Technical Specifications Technical Parameter Material & Construction Standard Garment Packaging Standard Modular Custom Matrix (Top & Trousers Sold Separately) Material Composition PowerStretch Hollow-Fiber (90% Polyester / 10% Elastane) Anti-Pilling Rating ASTM D 3512 - Grade 4.0 Verification Fabric Densities (Series Options) Body X: 285g/m2 | Body 2X (Extreme Cold): 665g/m2 Hardware Integration Pee Hose Prepared Ports / Slim Waist Cord / Elastic Anchors Environmental Consideration 100% Plastic-Free Ocean-Safe Packaging Technology BIOMIMETIC POLAR HOLLOW-FILAMENT MATRIX Standard fleece fibers rely entirely on the gaps between threads to hold ambient air. However, under drysuit squeeze, these gaps quickly collapse, resulting in a sudden drop in core body temperature. The Body X utilizes advanced hollow-filament polyester technology inspired by polar bear fur. By centering a permanent, air-filled pocket within each individual thread, the fabric preserves an indestructible inner layer of air that keeps insulating even under direct physical compression at depth. CAPILLARY ADVANCED WICKING ARCHITECTURE Physical exertion during gear transport or pre-dive setup generates rapid sweating. If this moisture is allowed to pool against the skin under water, it turns into a thermal bridge that drains body heat up to twenty-five times faster than dry air. The knit design of the Body X relies on capillary action to instantly draw sweat molecules away from the skin. It forces the liquid outward to the exterior jersey face where it quickly disperses, keeping the diver's skin perfectly dry throughout long tech-diving profiles. MODULAR COMFORT & UTILITY SCHEMATIC Because physiological cold sensitivity and muscle mass vary wildly across upper and lower body quadrants, fixed one-piece undergarments often compromise comfort. The Body X modular layout separates the top from the trousers, giving technical divers the freedom to vary sizing parameters or step up to the heavier 665g/m2 Body 2X layer on the torso while keeping the legs streamlined. This modular layout is finished with low-bulk flatlock stitching and factory-routed P-valve channels to ensure seamless integration into advanced diving systems.
