Endura Hummvee MTB Waterproof Jacket XL

The Endura Hummvee waterproof cycling jacket uses a 2-layer ripstop fabric with fully seam-sealed construction to keep rain out while allowing fast wicking for comfort on long rides. The lightweight mesh liner adds a touch of softness against the skin, and a PFC-free durable water-repellent (DWR) finish helps shed light showers. Ventilation is provided by underarm zipped vents to reduce heat buildup during climbs or hot laps on the trails. This model is designed to balance protection with the freedom needed for aggressive riding and pocket access on the go.
Endura Hummvee MTB Jacket M

This Endura Hummvee jacket mirrors the XL in structure with a 2-layer waterproof fabric and seam-sealed build. It maintains the same breathable mesh liner and underarm venting to prevent overheating during sustained climbs. The lightweight construction makes it easy to stash in a pack, and the waterproof finish supports riding through persistent drizzle typical of UK weather. It’s tailored for riders who value reliable protection without bulk.
Outdoor Ventures Rain Jacket

Outdoor Ventures offers a practical hooded rain jacket with fully seam-taped high-density nylon fabric and a TPU membrane to repel rain and wind while maintaining warmth. It’s designed for riding and running in variable drizzle, with breathable construction to wick moisture away from the body. The packable design means it can fold into its own pocket, making it a convenient backup layer for unpredictable UK conditions.
Altura Waterproof Jacket

The Altura waterproof jacket emphasizes visibility and weather protection. It features fully taped seams and an adjustable hood, making it suitable for cyclists who ride in heavy rain or light downpours. Reflective detailing enhances visibility in low-light conditions, while breathable fabric helps regulate temperature during exertion. It’s pitched as a versatile option for cycling and outdoor activities beyond MTB use, including running or walking in wet weather.
FDX Cycling Jacket Waterproof

The FDX waterproof cycling jacket is designed for versatility across MTB and road use. It’s described as waterproof and wind resistant with a lightweight, easily packable profile. Full sleeves and taped seams add durability, while breathable fabric and back/front vents support airflow for extended rides in changeable weather. The design aims to minimize riding up and maximize comfort on longer sessions in cool or wet conditions.
Buying Guide
- Protection level: Look for fully taped seams and a waterproof rating appropriate for UK rain. A two-layer or seam-sealed construction with a DWR finish is common in reliable MTB jackets.
- Breathability: Venting under the arms or back vents helps manage heat during climbs. Breathable fabrics prevent the “clammy” feeling on long rides.
- Fit and mobility: Jackets should allow full arm movement without riding up during pedalling. Consider a cut that suits your layering strategy for colder days.
- Weight and packability: If you carry a compact pack, a lightweight, foldable jacket is advantageous for sudden showers without adding bulk.
- Visibility: Reflective elements improve safety for riding in dawn/dusk light. Consider jackets with reflective trims on sleeves or back panels.
- Durability vs. flexibility: Ripstop fabrics and reinforced cuffs/hem prevent wear on rough trails while still offering comfort for daily use.
- Versatility: Some jackets double as outerwear for running or hiking, broadening their practical use beyond MTB.
- Care and sustainability: PFC-free finishes reduce environmental impact; check care instructions to extend the jacket’s life.
Across these options, UK riders should balance rain protection with breathability and weight to suit their typical trails and seasons. For frequent wet rides, a lightweight, packable shell with taped seams is a practical core choice; for cooler days, a jacket with airflow management helps maintain comfort without overheating. Always consider fit with your usual riding kit and whether you’ll wear additional layers underneath during colder months.
