"During the summer I'm always trying to keep my hydration levels high and you really can never carry enough, so that's where the 42MM Filter Cap comes into play. It's so clutch when you're deep in the woods and stumble upon a stream; it filters super quick, I know I can trust it and it fits nicely on my favorite SkyFlask (plus many other HydraPak products, too). Can't leave home for a long run without this small, yet essential piece."
