For those who don't like risking their luck when there's a chance of rain in the forecast, the two-in-one SUPER FLY PACK COVER offers a premium waterproofing experience. We engineered this cover with taped seams, 2.5x Nylon fabric (still breathable), and a built-in adjustable hood to keep both your pack and your noggin dry during misty mornings or when rainstorms blow in out of nowhere. With the SUPER FLY PACK COVER on hand, you can venture out into the backcountry with one less thing to worry about when the skies start to get dark.
