360 Reflective Mens Jacket – Jet Black

The 360 Reflective Mens Jacket combines reflective technology with practical water resistance. Its 360° reflective coating makes the rider highly visible from all angles when illuminated by bike lights, a valuable feature for night-time or early-morning cycling. The fabric is water-resistant, with a durable water-repellent finish to shed light rain. The jacket is lightweight, making it easy to wear over a base layer without overheating during longer rides or commutes.
For cyclists, the jacket’s lightweight profile and packability can be a decisive factor on crowded city routes or singletrack approaches where weight matters. It’s well-suited to rides in light showers or drizzle, rather than prolonged downpours, but its reflective properties enhance safety in low-light conditions.
360 Reflective: Jet Black, Long-Lasting Fit

This variant emphasizes a clean silhouette and reliable fit for cycling. The water-resistant design helps with light rain exposure, while the 360° reflective finish ensures high visibility when headlights hit the fabric. It’s a practical choice for riders who want a minimalist, packable layer that can be worn over jersey layers on cooler days or in transitional seasons.
360 Reflective Mens Jacket – Black 2XL

This size option offers a roomier fit, which can accommodate additional layers for colder rides. The same features apply: 360° reflective finish for visibility, water resistance for light rain, and a lightweight build for riding comfort. The jacket remains suitable for longer endurance sessions in temperate UK weather when paired with a base and mid-layer as needed.
360 Reflective Mens Jacket – Black 4XL

With a larger cut, this variant supports layering for riders who require extra space for insulating layers during colder seasons. The 360° reflective feature and water-resistant fabric deliver essential safety and function for those who ride in dawn or dusk hours, or on misty days when visibility is limited. It remains a practical pick for riders who prioritise fit across different body types and winter-ready setups.
Buying Guide: What To Look For In A Mountain Bike Rain Jacket
When selecting a rain jacket for mountain biking, consider protection level, breathability, and fit. Key factors include:
- Waterproof vs Water-Resistant: Choose a jacket with a waterproof membrane (e.g., taped seams) if you frequently ride in heavy雨. For light showers, a water-resistant shell with a durable water-repellent finish may suffice.
- Breathability: Look for vents or breathable fabrics to manage sweat during climbs. Poor breathability can lead to dampness inside the jacket, affecting comfort.
- Seams and closures: Taped seams prevent water ingress. Full-zip designs provide versatile ventilation, while cuff and hem adjustors help seal out rain and wind.
- Visibility: Iso-Vis fabrics and 360° reflective elements increase conspicuity in low light. This is crucial for road rides and mixed terrain where bikes share space with motorists.
- Fit and mobility: A cycling-specific cut with longer back coverage prevents ride-up. Consider a Scooped Back or articulated sleeves to maintain protection when reaching for handlebars.
- Weight and packability: Lightweight jackets that fold compactly suit riders who need to stow layers in packs or pockets during sunny spells.
- Compatibility with layers: Ensure the jacket accommodates base layers, hydration packs, or elbow/hip pads if you use protection on rough trails.
- Durability: Reinforced panels at high-wear zones extend the jacket’s life on rocky descents and brushy sections.
How To Use These Jackets On Mountain Trails
Layering remains essential. Start with a breathable base layer, add a moisture-wicking mid-layer if needed, and top with a rain shell during wet weather. On warm drizzle days, you may only need the shell over a light jersey. For night rides, prioritize products with strong reflective features and adjust for the extra cooling from air movement during fast trails.
Care And Maintenance Tips
Follow manufacturer washing instructions to preserve waterproof membranes. Rinse mud quickly, avoid fabric softeners that can impair waterproofing, and reproof the jacket as needed to restore water repellency after multiple washes.
