In 2025, men’s underwear is no longer just about covering essentials—it’s about comfort, style, and smart innovation. From cooling fabrics to odor-resistant finishes and ergonomic pouch designs, the underwear world is undergoing a quiet revolution driven by underwear tech.
At Sunin we believe comfort is a technology—one that blends form, function, and feeling.
1. Sustainable Fabrics with High-Tech Functionality
Today’s conscious consumers are demanding more than just fit—they want eco-friendliness without compromising performance. According to a 2025 trend report by KG Garment, over 62% of male consumers aged 18–35 now prefer underwear made from sustainable materials like bamboo viscose, TENCEL™, and organic cotton.
Our latest microfiber and modal-spandex blends at SONEI are designed not only for ultra-soft comfort but also for reduced environmental impact. These fabrics are biodegradable, sourced responsibly, and made in compliance with OEKO-TEX® and GRS certifications.
2. Cooling Tech That Works All Day
Sweaty commutes and summer heat demand more than basic breathability. That’s why advanced cooling technologies are being woven directly into the fibers. Brands like CDLP and On That Ass are exploring cool-touch yarns that regulate skin temperature.
SONEI uses cooling-treated modal combined with moisture-wicking Lycra® for all-day dryness. This isn’t just marketing—our wear tests showed a 15–18% lower surface temperature compared to traditional cotton blends.
3. Odor-Resistant and Antibacterial Features
Reddit user @Cliffhanger2023 on r/BuyItForLife said:
“I stopped using anything that doesn’t include silver ions or zinc oxide. Once you try odor-resistant briefs, there’s no going back.”
This insight is echoed across online communities, where antimicrobial finishes are now considered a must-have for modern men.
Our antibacterial series at SUNIN uses silver ion treatment, which reduces odor-causing bacteria by up to 99.5% after 20 washes. Whether for travel, gym, or daily wear, this technology keeps underwear fresh and hygienic.
4. Ergonomic Pouch Designs for Real-World Comfort
Men are realizing that pouch design isn’t just a gimmick—it’s a game-changer. A recent TBO Clothing survey found that 68% of men preferred ergonomically contoured pouches over flat fronts for better support and ventilation.
At SUNIN, we design with the male form in mind. Our 3D comfort pouch offers natural lift without constriction, perfect for everything from long office days to high-intensity workouts.
5. Merging Innovation with Minimalist Style
While tech leads the way, style still matters. The rise of “quiet luxury”—clean lines, neutral tones, and subtle branding—proves that modern men value sophistication over flashy designs.
Our new 2025 collection embraces minimalist aesthetics with ultra-soft waistbands, tonal stitching, and custom-logo options for private labels. All while maintaining maximum performance through underwear tech.
