This is a lightweight 780ml aluminum bottle. I bought it for hydration during training but never used it. I opened the box for the purpose of taking photos. This is a set of 3 bottles: one red and two green. It uses silicone for the packing, so there should be no worries about leaks. How about buying them in bulk with your gym buddies? It has a sufficient capacity. It might also be good to have multiple bottles to put different flavored drinks in. Shipping: Yamato 60 size Shipping will be on Saturdays and Sundays. If payment is received on a Sunday, shipping will be on the following weekend. Simple packaging will be used. Other: I am not considering price reductions. Returns are not accepted, so please understand this is a no-return, no-claim (NR, NC) sale. The ruler is not included in the product. #training #hydration #aminoacids #heatstroke #waterbottle
