All new, the 4.5 HydraDri pant is both waterproof, and breathable, but gives a lightweight and comfortable feel, more like a traditional riding pant, rather than the usual slippery, uncomfortable waterproof products available. This is possible due to the combination of stretch materials, and Leatt’s own 3-layer, waterproof, breathable membrane. Tested to surpass waterproofness of 20,000 mm+….so what does this mean? Well basically these pants are good for use in heavy rain, and wet snow under high pressure!! Also surpasses 20,000 breathability….so once again what does this mean? As well as not allowing water in, this clever material allows moisture from your body to be expelled to help keep you cool!! There are 3 storage pockets, and zipped ventilation for when the rain stops, and the sun comes out. This is an in-boot design, with multi-layer material for inner knee reinforcement using Leather for grip. A combination of 360° heavy duty silicone grip and waterproof YKK zippers, will make sure the pants stay in place.
