Nature's Best Materials, Engineered for Peak Performance
Unlocking Nature's Full Potential Through Intelligent Design.
For decades, hunters have compromised: warmth or breathability, comfort or durability, natural fibers or performance. Hillman's game-changing SYNERTECH™ technology eliminates these trade-offs by combining nature's best materials in revolutionary ways never seen before. This proprietary merino wool-bamboo fiber blend multiplies performance beyond what either material can achieve alone, delivering the ultimate foundation for serious hunters who refuse to compromise.
Temperature Regulation Across All Conditions
Dawn's freezing temperatures, midday warmth, evening cooling - your body temperature management system faces constant demands. SYNERTECH™ base layers effectively extend your comfortable temperature range, allowing you to hunt longer in more varied conditions with less gear.
SYNERTECH™'s natural fiber blend provides dynamic thermal regulation that automatically adjusts to changing conditions and activity levels, maintaining optimal comfort. Merino wool's crimped fiber structure traps insulating air pockets while allowing excess heat to escape.
The Science of Synergy
SYNERTECH™ represents a fundamental breakthrough in technical fabric engineering. By precisely blending ultra-fine merino wool with natural bamboo fibers, we've created a material that doesn't just combine benefits - it multiplies them. The result is 50% more efficient moisture management, superior thermal regulation, and enhanced durability compared to pure merino wool.
This isn't simply mixing two materials. SYNERTECH™ employs advanced processing techniques that allow merino's exceptional insulation and bamboo's superior moisture-wicking properties to work in perfect harmony. Each fiber enhances the other's strengths while compensating for limitations, creating performance that exceeds the sum of its parts. The synergistic effect delivers unprecedented efficiency for hunters facing extreme and variable conditions.
Unmatched Comfort Against Your Skin
Synertech's innovative construction places ultra-soft bamboo fibers directly against your skin, creating a silky-smooth barrier that eliminates the scratchiness sometimes associated with wool. While merino's exceptional insulation works from the outer layer, bamboo's gentle touch ensures all-day comfort without irritation. Experience the perfect balance: merino's warmth with bamboo's luxurious softness for extended wear.
Natural Odor Elimination Technology
Scent control can make or break a hunt. SYNERTECH™ provides natural, permanent antibacterial protection that synthetic treatments can't match. Both merino wool and bamboo fiber possess inherent antimicrobial properties that prevent odor-causing bacteria from colonizing the fabric. Unlike chemical treatments that wash out over time, SYNERTECH™'s odor resistance is built into the fiber structure itself.
This natural defense system works continuously without degrading. The combination of merino's keratin protein structure and bamboo's natural bamboo kun agent creates an inhospitable environment for bacterial growth. Extended hunts without washing opportunities? Multi-day backcountry expeditions? SYNERTECH™ base layers stay fresh and scent-free, keeping you undetected when it matters most. This permanent odor resistance delivers confidence that lasts season after season.
Superior Comfort for Extended Wear
Comfort directly impacts hunting performance. Distraction from itchy, clammy, or restrictive base layers ruins focus and endurance. SYNERTECH™ delivers exceptional next-to-skin comfort, allowing complete concentration on the hunt. The ultra-soft fiber blend feels soft against skin while providing technical performance that keeps you comfortable from dawn to dusk.

Unmatched Moisture Management
Effective moisture management is critical for maintaining body temperature and comfort during variable activity levels. SYNERTECH™ excels at moving moisture away from skin and facilitating rapid evaporation - drying up to four times faster than cotton. This superior performance prevents the dangerouts combination of sweat and cold that leads to hypothermia in extreme conditions.
The hybrid fiber structure creates an optimal moisture transport system. Bamboo's hollow fiber structure pulls moisture away from skin through capillary action, while merino's hydrophilic exterior and hydrophobic interior facilitate rapid transfer to the fabric surface. There, both materials' high surface area promotes fast evaporation. The result: you stay dry during intense activity and maintain warmth during rest periods, regardless of weather conditions.
Sustainable Technology
SYNERTECH™ combines high performance with environmental responsibility. Both merino wool and bamboo are renewable, biodegradable natural fibers with significantly lower environmental impact than synthetic alternatives. Merino sheep produce new fleece annually, while bamboo grows rapidly without pesticides or irrigation.
Choosing SYNERTECH™ means investing in gear that performs exceptionally while respecting the wild places we hunt. The natural durability of these fibers means garments last longer, reducing replacement frequency and overall environmental impact. Unlike synthetic base layers that shed microplastics with each wash, SYNERTECH™ fabrics return harmlessly to nature at end of life.

Started with the 2BL base layers, then added the hoodie. Now my entire foundation is Synertech and my hunting comfort has never been better. The consistency across products means perfect layering compatibility. Every piece performs as advertised. Hillman has earned a customer for life.

Wore synthetic base layers for 15 years. Made the switch to Hillman's Synertech line this season and won't go back. Natural fibers just perform better for hunting - no plastic smell, genuine odor resistance, more comfortable temperature regulation. The Synertech blend gives you all the benefits of natural materials with performance that rivals or exceeds synthetics. Worth the investment.

I sweat heavily during the walk to my stand, and regular base layers always left me cold and damp once I sat down. The 2BL long johns wick moisture so fast I'm actually dry by the time I'm settled in. Wore them through November's rut in temps from 20-45°F and never once felt uncomfortable. The bamboo blend really does make a difference - these dry in half the time of my pure merino stuff.

Guided hunts for 20 years, tried every base layer on the market. These are the real deal. Synertech delivers warmth without the bulk of heavier layers. Clients constantly ask what I'm wearing because I'm comfortable while they're freezing or sweating. The odor resistance is legit - I've gone a full week without washing on remote hunts. Finally found base layers I can recommend without hesitation.

Sit all day in Iowa cold and these keep me hunting longer. The fit is perfect - not too tight, moves with you. What impressed me most is how they regulate temperature. Morning sits at 15°F, afternoon warming to 40°F, and I stayed comfortable the whole time. No more layering and unlayering constantly. The Synertech technology isn't just marketing hype.

The 3ML hoodie is incredibly versatile. Worn as outer layer in 50°F weather, mid-layer in 20°F weather - works perfectly either way. The moisture management is excellent during uphill climbs, and it breathes way better than my synthetic hoodies. Love that it's merino-bamboo blend - gets all the benefits of merino without the weight. Three weeks of hard hunting and still looks brand new.
