DURABILITY. Exo-Skeleton strategically strengthens wear points for maximum abrasion resistance. Corners reinforced with hypalon material prevent fraying, while ripstop and ballistic fabrics add reinforcement and create a water repellent exterior. INTERIOR. Compartment on top of bag is great for quick grab items, plus large pocket can act as a laundry shoot or be used to separate gear from clothes. Compression straps inside secure contents and keep clothing wrinkle free. ALL CONDITIONS. Oversized treaded wheels in protective wheel housing for smooth mobility on any surface. Exterior lockable zippers have finger-friendly pulls so you can grab them even with gloves on. Reflective accents ensure you stay visible in the dark.
