Love lots but ONE little issue :(

I love how cold it keeps my water and for how long that is AMAZING!!! I absolutely adore how spill proof it is cause I am like a toddler, but the inside of the stew on top of the bottle gets pretty gross pretty fast and the inside plastic straw is actually moldy (despite me washing it twice already) and the dark color will not come out… so i need to buy a new straw which is a bummer cause it’s so soon after my purchase! Color is amazing tho and like I said so is the insulation it’s just something with the plastic straw! Thanks for hearing me out love a lot of my other products I’ve purchased from you!

Beautiful color.

Great and beautiful color. Cap came defective. Drinking stem. Is weirdly loose.

40oz wide mouth with straw

Takes a bit of getting used to but it’s an improvement over the previous flip lid system that stains and won’t come clean. I take it everywhere and am getting used to positioning the straw top wide open so I don’t get air. Overall I do like it!

Excellent sport bottle

Best bottle hands down for swim / waterpolo. My kid loves it and is easy to grab poolside without spilling because of the built in straw. Excellent.

My fav size bottle

With two toddlers, it’s hard for me to use the 40oz tumbler so I love the bottles because they don’t leak and I can take them everywhere with me!

Dented within one month

Great bottle, but like others, they dent. I thought the boot would minimize the denting but I was wrong. Dropped from chest level and fell on the floor, right side up, so it landed on the boot. Now the flask is so dented it doesnt stand upright. Annoyed at myself for believing the boot would do anything and Im left with metal recycling after a month.
