MSR vs. Kelty: Which brand offers better waterproofing?

Waterproofing Coatings and Seams

MSR’s WaterGuard coating is a polyurethane-based treatment that provides excellent waterproofing and durability. This coating is applied to both internal seams and external surfaces of their tarps and shelters. In contrast, Kelty’s waterproofing methods often rely on silicone-based coatings or seam sealing techniques, which can be less effective in wet conditions.

Tarp Fabric and Weave

The type of fabric and weave used in a tarp can also impact its waterproofing performance. MSR’s tarps typically feature a ripstop nylon fabric with a 1000 denier rating, which provides excellent strength and water resistance. Kelty’s tarps, on the other hand, may use a variety of fabric types, including polyester and nylon, with denier ratings ranging from 300 to 600.

Seaming and Stitching Techniques

The way a tarp is seamed and stitched can significantly impact its waterproofing. MSR’s tarps are constructed with a strong, reinforced stitching technique that ensures seams are sealed and watertight. Kelty’s tarps, while still well-made, may use a more traditional stitching method that can be more prone to leaks. By using a proprietary seam-sealing tape and carefully sealing internal seams, MSR’s tarps achieve a higher level of waterproofing that can withstand even the most extreme weather conditions.
