What makes it waterproof? Look for unique design features in our rainwear and waterproof jackets such as sealed seams, adjustable body-conforming cuffs and collar, storm fly fronts and more that ensure you stay both dry and warm during your shift. At Blauer, waterproofing isn't just an afterthought coating on our jackets; it's ingrained into our patented fabric. Our unique design ensures water shedding is inherent, providing long-lasting waterproof jackets and gear that won't falter with washing or wear over time.
