Wag Trendz Launches NeoCool Patent-Pending Cooling Dog Harness with Airflow Technology

As rising summer temperatures and extreme heat advisories continue across the U.S., veterinarians warn that dogs can quickly develop life-threatening heatstroke during everyday walks and outdoor activity because they primarily rely on panting — not sweating — to regulate body temperature.

At the same time, dog owners are becoming increasingly aware that many traditional harnesses and cooling products were never designed with long-term breathability, airflow, or heat and moisture retention in mind. Existing cooling gear often relies on soaking, bulky inserts, or short-term evaporative cooling methods that lose effectiveness throughout the day.

To address this growing need, Wag Trendz, a female-owned urban dog gear brand known for combining streetwear-inspired aesthetics with safety-first functionality, announces the launch of NeoCool, a first-of-its-kind patent-pending cooling dog harness engineered with advanced passive airflow technology to help reduce heat buildup and improve comfort for dogs year-round.

Developed after years of nationwide road testing and direct customer feedback, NeoCool was created to solve a recurring problem the founders repeatedly heard from dog owners at events and pop-ups across the country: they wanted breathable gear that delivered genuine cooling performance without sacrificing durability, comfort, or style.

Unlike traditional cooling vests that require soaking to activate, NeoCool is engineered to perform completely dry through a patent-pending perforated construction paired with breathable quick-dry air mesh. Third-party lab testing found NeoCool provided more than 2.5x greater airflow and reduced heat and moisture retention by 85% or more compared to traditional harness constructions. The lightweight dual-layer design is intended to promote continuous airflow, dissipate trapped heat, and reduce heat retention during everyday wear, outdoor adventures, hikes, travel, and city walks.

On especially hot days, the harness can also be lightly soaked or chilled for additional evaporative cooling support, giving dog owners flexibility depending on climate and activity level.

“Over and over again, we heard the same frustration from dog owners: traditional harnesses were trapping heat, and many cooling products felt bulky or impractical for daily use,” said Michelle Clayton, co-founder and CEO of Wag Trendz. “My co-founder, Sarah Roberson, brought more than 12 years of veterinary experience into the design process, and together we wanted NeoCool to feel genuinely wearable for real dogs — lightweight, breathable, supportive, and comfortable enough for everyday adventures while still helping dogs stay cooler naturally.”

NeoCool is especially beneficial for active dogs frequently exposed to warm sidewalks, hiking trails, outdoor festivals, and urban environments.

Key NeoCool features include:

• Patent-pending perforated airflow construction
• Advanced passive airflow technology designed to promote ventilation
• Breathable quick-dry air mesh interior
• More than 2.5x greater airflow than traditional harnesses
• Cooling performance that works dry — no soaking required
• Lightweight structured fit with enhanced durability
• Ergonomic no-pull harness design with front and back leash clips

Founded in Austin, Texas in 2021 by sister-in-laws Michelle Clayton and Sarah Roberson, Wag Trendz spent three years road-testing products nationwide and refining every feature through real-world feedback from dog owners and their pets. The NeoCool Sport Collection includes harnesses, collars, adjustable leashes, and coordinating accessories available in multiple styles and colors.
