About the Product

Built for mountain racing, trail riding, XC riding, cycling, running, and other high-output outdoor sessions, this men’s windproof long sleeve jacket is designed for athletes who need front wind protection, rear heat release, and lightweight packability in demanding conditions.

It performs especially well in foggy, cold, and high-humidity weather, where airflow control and core protection matter more. The front uses 50D cotton-touch memory fabric made from 100% polyester, with a fabric weight of 86 g/m². It delivers a lightweight windproof structure, water-repellent surface performance, a quick-dry rate of at least 0.25 g/h, and UPF 50+ sun protection.

The overall construction focuses on lighter weight, lower bulk, better body conformity, and easier carrying. With 4 rear ventilation holes, dual front pockets, reflective safety details, a two-way zipper design, and packable storage into approximately 15 × 22 cm, it is made for riders and runners who want a practical outer layer that protects without feeling heavy.

1. Ultralight Windproof Front Shell

The front panel uses 50D cotton-touch memory fabric with a weight of 86 g/m², creating a light outer layer that helps block cold wind from reaching the core. Compared with heavier outer shells, this fabric structure reduces bulk and improves mobility during climbing, sprinting, and repeated high-output effort.

For mountain riding and race-paced movement, lighter weight matters because it reduces drag from excess fabric and makes layering easier. This gives the jacket a more responsive feel in conditions where protection is needed but heavy insulation would be too much.

2. Water-Repellent Protection for Fog, Moisture, and Cold Conditions

The front fabric is designed with a water-repellent surface, helping reduce the impact of light moisture, fog, and damp air during outdoor sessions. In cold and humid environments, surface water resistance helps prevent the fabric from wetting out too quickly, which supports more stable comfort during movement.

This makes the jacket especially practical for early-morning riding, foggy mountain routes, damp trail sessions, and cold-weather running, where the challenge is often not heavy rain, but persistent moisture combined with wind exposure.

3. Rear Ventilation with 4 Breathable Holes

To balance front protection with rear heat release, the back is designed with 4 ventilation holes. This structure helps hot air escape more efficiently from the back panel, reducing the stuffy feeling that often happens when windproof outerwear is used during intense movement.

For riding and running, thermal balance is critical. When the front blocks wind and the back can release excess heat, the garment becomes more usable across variable intensity. This is especially important in mountain terrain, where effort changes frequently between climbing, descending, and recovery.

4. Quick-Dry and More Practical for Repeated Use

The fabric offers a quick-dry rate of at least 0.25 g/h, which supports faster drying after sweat exposure or surface moisture contact. In practical wear, this helps the jacket recover faster between sessions and reduces the damp-on-skin feeling during repeated short or medium-duration use.

For riders and runners training in cool but humid conditions, drying efficiency improves day-to-day practicality. It supports better comfort during pack-and-go use, commuting transitions, or back-to-back activities.

5. Reflective Details for Better Low-Light Visibility

The jacket includes multiple reflective safety elements. There is a reflective heat-transfer detail on the left chest measuring 1 × 7 cm, and a low-position reflective strip on the rear pocket measuring 1.8 × 5 cm. These details help improve visibility cues in low-light conditions such as fog, dawn, dusk, and overcast weather.

For mountain riding and road transitions, visibility matters because light conditions often change quickly. Reflective accents do not replace lighting equipment, but they improve visual recognition and add a practical safety layer during movement.

6. Two-Way Zipper for Easier Venting and Faster On-Off

The jacket uses a #3 reverse two-way open-end nylon zipper with a pull-cord length of 4.5 cm. This design supports two-way opening, smoother operation, easier dressing and undressing, and a cleaner concealed look. The longer pull cord is also more user-friendly for riders with larger hands or when gloves are worn.

A fabric zipper guard is added near the collar to help prevent neck rubbing or zipper-head irritation. Together, these details improve both function and wearing comfort in real movement.

7. More Stable Fit Without Tight Restriction

The jacket is finished with a 1 cm wide sleeve cuff and a 2 cm elastic binding at the rear hem, creating a more stable fit against the body. This helps improve wind control while reducing edge movement during riding or running.

The result is a fit that feels lighter, thinner, and closer to the body, while also helping reduce common issues such as tightness, rubbing, or edge rolling. For high-cadence movement, that balance between stability and freedom is critical.

8. Dual Front Pockets Plus Packable Storage Design

The jacket includes 2 front pockets, each with a pocket height of 19 cm, giving practical storage space for daily outdoor essentials. This improves convenience during riding, trail use, or short-distance running when small items need to stay accessible.

The left pocket uses a two-way zipper and also works as a packable storage pocket, allowing the jacket to be folded into a compact size of approximately 15 × 22 cm after packing. This makes it easier to place in a storage box, backpack, travel bag, or gear kit, which improves portability for users who need a weather-ready outer layer without taking much space.
