DRYHUNT® NANOMEMBRANE: Breathability Engineered for Hunting
The hunting industry settled for membranes designed for mountaineering and skiing - activities nothing like hunting. GORE-TEX and competitors offer solid hydrophilic membranes where moisture escapes through slow, condensation-like processes. Hillman's Dryhunt® nanomembrane changes everything. Engineered exclusively for hunting, it provides direct breathability through nanopores 0.5 microns wide - allowing instant moisture vapor escape while blocking water droplets 20 times larger. With 360° elasticity, complete silence, and PTFE-free construction, Dryhunt® outperforms every membrane in the hunting industry for what matters most: breathability, mobility, and stealth.
The Electrospinning Breakthrough
Dryhunt® utilizes advanced electrospinning technology to create its revolutionary nanoporous membrane. This process applies high voltage to polymer solutions, drawing ultra-fine nanofibers that deposit randomly to form a three-dimensional network with precisely controlled pore architecture. Unlike GORE-TEX's mechanical stretching of fluoropolymers, electrospinning creates inherently breathable structures without requiring chemical layers or backing materials that restrict airflow.
The randomly oriented nanofibers create a stable mesh with 0.5 micron nanopores - the optimal size for blocking water while allowing unrestricted vapor transmission. This manufacturing precision delivers 360° elasticity because the three-dimensional fiber network stretches naturally without compromising pore structure. Traditional stretched membranes lose waterproofness when extended. Dryhunt® maintains full protection even under critical tension, providing mobility without performance sacrifice.
Direct Breathability: The Game-Changing Difference
99% of membranes out there are solid hydrophilic membranes that don't offer direct breathability. Moisture escapes through these membranes via a condensation-like process, which is highly inefficient and fails to effectively release excess moisture during hunting activity. GORE-TEX forces perspiration through chemical layers that dramatically slow vapor transmission, leaving you damp and uncomfortable.
Dryhunt® provides direct air transmission through its nanoporous structure. As you move, sweat vaporizes and passes instantly through 0.5 micron nanopores - not through slow chemical diffusion. A vaporized sweat molecule measures just 0.000275 microns and easily passes through, resulting in 32,000 g/m²/24h breathability - hundreds of times more efficient than GORE-TEX. This keeps you dry during intense climbs and comfortable during stationary sits, because air flows continuously through the membrane regardless of activity level.
Waterproof Protection Through Nanotechnology
The science of Dryhunt®'s waterproofness is elegantly simple: a water droplet measures 10 microns (μm), while Dryhunt® membrane nanopores measure just 0.5 μm - 20 times smaller. This size difference creates absolute physical barriers that water droplets cannot penetrate, delivering 11,000mm waterproof protection.
This 11,000mm rating exceeds any realistic hunting scenario, even extreme conditions rarely exceed 5,000mm. Dryhunt® provides over 100% safety margin while maintaining superior breathability that solid membranes sacrifice for extreme waterproof ratings you'll never need. The nanoporous structure remains waterproof even when stretched, because the 0.5 micron pores maintain their size during fabric extension. Rain beads off, snow doesn't penetrate, ground moisture stays outside - all while your perspiration escapes freely.
The Science of Silence
After hundreds of acoustic tests, we discovered noise absorption depends on brushing volume, fabric density, and yarn thickness. Heavy fleece fabrics absorb sound well but add unacceptable bulk. The challenge: create thin, lightweight fabric with equivalent sound absorption properties.
The breakthrough came through nano-polyester fiber technology. These fibers create several times more surface hairs per square inch after brushing than conventional fabrics. This dramatically increased surface area absorbs sound energy that would otherwise transmit audibly. Bonded with resonance-absorbing materials, Dryhunt® membrane becomes a silent weapon. The result: Dryhunt® shell fabric performs better in noise absorption than any fabric in its weight class. Brushing against branches, contact with gear, movement in stands - all remain whisper-quiet. Game animals possess acute hearing that detects fabric rustling instantly. Dryhunt®'s engineered silence keeps you undetected when stealth matters most.
PFAS-Free Performance Without Compromise
GORE-TEX and competitors require PTFE and fluorochemicals that persist indefinitely in ecosystems and accumulate in organisms. Dryhunt®'s polyurethane nanofiber construction eliminates these risks entirely while delivering superior breathability through direct nanoporous architecture rather than fluorinated chemistry.
The nanoporous structure achieves waterproof breathable performance through engineering, not harmful chemicals. No fluorinated polymers needed. No persistent environmental contaminants. Just advanced material science creating membranes that protect you without poisoning the wild places you hunt.
Why Dryhunt® Outperforms GORE-TEX
GORE-TEX pioneered waterproof breathable membranes but uses fundamentally inferior technology for hunting applications. The differences are measurable and significant.
Breathability: Dryhunt® provides direct air transmission through nanopores achieving 32,000 g/m²/24h. GORE-TEX forces moisture through solid hydrophilic chemical layers at 25,000 g/m²/24h - 28% less efficient. Result: You stay drier during activity.
Stretch Mobility: Dryhunt® offers 360° elasticity maintaining waterproofness when stretched. GORE-TEX remains rigid, restricting movement. Advantage: unrestricted mobility for shooting positions.
Silence: Dryhunt®'s nano-polyester construction with resonance-absorbing bonding creates acoustic stealth. GORE-TEX fabric generates audible rustling. Advantage: remaining undetected.
Environmental: Dryhunt® contains zero PTFE and harmful fluorochemicals. GORE-TEX requires PTFE throughout. Advantage: no forever chemicals contaminating ecosystems.
GORE-TEX optimized for mountaineering decades ago. Dryhunt® optimized specifically for hunting today.
