Seems bomb proof. Made a waterproof back for bike commuting. Fit into my non waterproof pannier. Used waterproof zipper and sealed with gear aid seam grip WP. Holds air fairly well so thinking it will be decent level of waterproof. Thick and material still fairly easy to work with. For strong, waterproof, material it’s a good choice. 4.8 oz per yard per site product info. For comparison, hyper D 300 is 3.9 oz/yard and XPac XV 21 is 6 oz/yard. Purchased all 3 of these to determine best choice for this produce and happy with LS21 choice. Thanks ripstop!
Thanks for your review Kris! We're glad that you found the perfect fabric for you bike adventures, enjoy!
