Think of the Outlier Ultrahigh Big Box Bag as a tote bag on steroids. It’s constructed from a material that sounds complicated — Ultrahigh Dyneema Composite — but all you have to know is that the nonwoven fabric is waterproof, light, strong and super stable. The black finish has a unique angular texture that will deepens as it ages, and the bag folds up flat and compactly for easy storage. When you do break it out to haul your gear, there are two shoulder straps and two hand straps to allow multiple carry options for convenient versatility.
