Nylon Banana Bag

[Usamah]

I saw an unfilled, nylon 6ft. heavybag at Amber Martial Arts for $80.00 (http://www.ambersports.com/nylunthabag6.html).
Has anyone tried this bag and what are your thoughts on the nylon material?

I'm familiar with leather, vinyl, and canvas heavybags, but I've never seen a nylon bag. Any insight is appreciated. Thanks.

I did a little further research (at other sites that have "nylon" bags) and it seems that nylon bags are bags that are vinyl-coated
18 oz canvas/nylon material.

If anyone knows otherwise, please comment. Thanks.
