These are the original bags Red Oxx developed from the parachute bag layout. Simple, no pockets, no extras, just solid durable bag with a large opening, a tough as nails #10 YKK zipper, and a plain super strong handle. Available in four convenient sizes, the Red Oxx Kit Bags also now feature Nickel plated D-rings for those who wish to buy a shoulder strap and shoulder carry their bag. The Extra Small Kit Bag and Small Kit Bags are both carry-on legal. The Medium and Large Kit bags make excellent sports equipment bags. All four can be folded down to take up very little space and packed in you other bags for use during your adventures.
