The wilderness wizards at Mountain Safety Research have created a new type of waterproof coating that will keep their Hubba NX backpacking tents drier for a lot longer. Traditional seam seals and tent waterproofing break down over time due to exposure to moisture and humidity and eventually start to leak. The brand’s Xtreme Shield polyurethane (PU) coating is better than that. It’s got a molecular chain that was engineered to eliminate deterioration, so your tent stays not only dry but never gets that sticky, flaky residue that inevitably occurs. The Hubba NX tents are available in solo, 2-person, 3-person, and 4-person models.
