The Ultra-Sil™ Pack Cover ends the debate about whether you should carry one or not. It's a tiny and compelling solution and the medium size weighs less a mere 4 ounces. Packs into its own small stuff sack - why wouldn't you carry one?

Pro Tip: ?If you stow any gear externally on your pack, Sea to Summit would recommend buying an Ultra-Sil Pack Cover a size larger than normal.
