Review on Tomnk 9pcs Collapsible Water Bottles: Reusable Canteen Bags with Clip for Sports, Biking, Hiking & Travel - 9 Colors by Mohammad Pesqueira

Tomnka bottles are great for hiking. Since the plastic isn't rigid, it shouldn't contain BPA or similar estrogen disruptors. :-) It's as light as any refillable water bottle. :-) It stands and folds for carrying too. The colors are great for loaning to other tourists. And 9 bottles for $10 is a steal. :-) I'm delighted, but they just arrived. If I encounter any problems after using it, I may revisit this review.
