Eastbay Windbreaker Jacket
Our Eastbay Windbreaker Jacket delivers lightweight protection for athletes who train in any conditions. Built with water-resistant ripstop fabric, this windbreaker blocks wind and light rain while maintaining breathability during high-intensity workouts.
The packable design collapses into its own pocket for easy transport in your gym bag or locker. We engineered this jacket with an athletic fit that layers comfortably over performance apparel without restricting movement. Reflective details enhance visibility during early morning or evening training sessions, while the adjustable hem and cuffs let you customize coverage and seal out the elements.
Performance fabric & fit details

Fabric Technology & Construction
The Eastbay windbreaker uses high-tenacity ripstop polyester with a durable water-repellent (DWR) finish that causes moisture to bead and roll off the surface. This construction creates a barrier against wind speeds up to 20 mph while maintaining air circulation through the mesh lining.
We reinforced stress points at the shoulders and elbows with bar-tack stitching to withstand repeated wear during athletic activities. The ripstop weave pattern prevents tears from spreading if the fabric snags during outdoor training. Inside, the partial mesh lining wicks moisture away from your base layers while allowing heat to escape during interval workouts or warm-ups.

Sizing, Fit & Layering
Athletic Fit Design
We cut the Eastbay windbreaker with an athletic fit that follows your natural shape without excess fabric. The tailored silhouette accommodates one or two base layers underneath — perfect for wearing over a performance tee or hoodie during cool-weather training.
Sleeves are pre-curved at the elbow to match your arm position during running or cycling. The dropped back hem provides additional coverage when you’re bent forward on a bike or stretching between sets. Raglan sleeves eliminate shoulder seams that can chafe during repetitive movements.
Packable Storage & Portability
The jacket’s packable design transforms it into a compact bundle that fits inside your gym bag, backpack, or locker. Simply stuff the entire jacket into the built-in chest pocket and secure it with the internal snap closure. The compressed bundle measures approximately 7 x 5 inches — about the size of a water bottle.
This portability makes the Eastbay windbreaker essential for unpredictable weather conditions. Keep it in your car for post-workout warmth, toss it in your travel bag for tournament weekends, or stash it in your cycling jersey pocket for mountain descents. The lightweight construction adds only 8 ounces to your load, so you’ll barely notice it until conditions change and you need protection.

Eastbay Windbreaker Jacket Questions

The 3M Scotchlite reflective trim is designed to maintain visibility through hundreds of wash cycles when cared for properly. We recommend washing the jacket inside-out on a gentle cycle to protect the reflective material from abrasion.
Avoid using bleach or fabric softener, and tumble dry on low heat or hang dry. Following these care instructions preserves the reflectivity for the life of the garment.

Rain jackets use waterproof membranes that block all moisture but can trap heat and sweat. The Eastbay windbreaker is designed for active training where you need wind protection and light weather resistance without sacrificing ventilation.
Yes, the Eastbay windbreaker follows standard men’s athletic sizing. Order your usual size for a true-to-size fit that accommodates one lightweight layer underneath.

The windbreaker works well as an outer layer for running in temperatures between 45-65°F. Pair it with appropriate base layers for colder conditions — the wind-blocking fabric and breathable lining prevent heat loss while allowing moisture to escape.
For temperatures below 40°F, you may need additional insulation underneath. The athletic fit and lightweight construction make this windbreaker ideal for interval training and tempo runs where you generate significant body heat.
