Valhalla Pure has long believed that Repellency is critical to product performance, so much so that we have given its own category. Repellency treatments act to restore and enhance backpacks, sleeping bags, rainwear, soft shell, down clothing and footwear. Specific formulations work best on their target application but the key is to realize how important reapplying repellency is, then 'just do it'. Protect your investment in your outdoor gear, keep it in prime condition.
