I purchased the large Mountain Duffle Bag. It's super lightweight, made from denier poly nylon.  It comes inside of a small travel Zip pouch that doubles as a toiletry tote which holds large shampoo bottles, I mean It holds alot of stuff--But you're wasting your time LOL...trying to get that big Mountain Duffle Bag back in there, Nope can't Get'er Done! LOL.  The Mountain Duffle Bag has a large "U" shaped top opening for easy packing, two large zippered end panel pockets, front side pocket, rip-grip carry handle, adjustable shoulder strap and two end straps. This duffel comes in small, medium, large and extra large, simply choose the one that works best for you.  The large Mountain Duffle Bag was my choice, its 30 inches side to side X 15 inches front to back X  15 inches top to bottom, Comes with an Awesome "Lifetime Warranty" against defects and folks...You can't go wrong when it says Life-Time from Mountain Duffle Bag's ! So order yours today and stop worrying about all the other worthless crap out there. Oh FYI, Mine was deliver in 24 hours and I did nothing special nor asked for that service. Simply unheard of today. I give this (**********) Ten stars!
