My bag size 16”wide x 23”tall x 10”deep (can be closer to 11 deep if extra zipper is let out)I was looking for a thick, well made luggage skin to mostly protect from handlers opening my zippers w a pen (even though I use a TSA lock) and stealing contents. Lastly some protection from scuffs after being tossed around and a deterrent for luggage thieves taking my usually unnoticeable black bag and walking away from the carrousel (ie a thief might think “not taking THAT one cause everyone will notice ?).The skin is sturdy, lined with a second stretch material. The two openings at the top have bias that is well sewn on and openings fit appropriately in the places for the telescopic strap and cloth handle. It was very easy to slip on and just snug enough to cover the whole suitcase including the edges at the bottom. The heavy plastic zipper meets perfectly for my size suitcase (no sagging) and black straps from bottom sides cover it when snapped together.Color and design are not too garish (my husband asked why I didn’t get plain black—-until I explained it was subtle enough for him to use and feel manly ?) and easy enough to spot on the luggage carrousel. Price was GREAT especially since it was so well made. I ordered a MEDIUM. I had also ordered a Large in case the M Was too small but never even opened that package when it came since the M fit perfectly. Returning the L today. I LOVE it so far. Leaving tomorrow and will update after I return from this trip!UPDATE 19 August 2024: pictures 1&2 are after one flight, pictures 3&4 are after a second. It got mildly scuffed up but I am definitely pleased w the outcome. It protected my suitcase and am convinced an airline employee who might want to break into it would be dissuaded because of having to remove it. I am very happy w the purchase!
