"What Our Gearhead® Experts Are Saying:""The AllMtn 4. 0 Jersey is my top pick for long rides. The IceYarn fabric is awesome for staying cool, and the dirt and water resistance mean I don’t have to worry about getting messy on wet trails. The three-compartment cargo pocket is great for stashing snacks and tools, and the longer back offers coverage without sacrificing mobility. Plus, the reflective trim adds a bit of safety for dusk rides.""When we're hitting challenging trails or pushing through unpredictable weather, the Leatt MTB AllMtn 4. 0 Jersey has our back. The innovative IceYarn fabric—crafted from recycled coffee grounds—naturally cools us down when the ride heats up, while the laser-perforated panels provide extra breathability. Designed with durability in mind, the jersey's anti-abrasion and anti-cut panels handle rough terrain without a hitch. We love how practical this jersey is. The three-compartment cargo pocket holds our essentials, secured with a concealed waist belt to keep everything in place. The longer back gives extra coverage, while the hip split keeps us moving freely. Reflective trim enhances visibility in low light, and the UPF 50+ protection guards against harmful rays. Whether we're cruising on our eBikes or grinding out a climb, the AllMtn 4. 0 Jersey keeps us cool, comfortable, and ready for the next challenge."
