Hydro Flask Medium Tumbler Boot Black

Such a perfect size for my water bottle

Good little addition to my hydro flask. No loud clunk every time I put the flask down. Add's a little bit of width but still fits in my car cup holder.

Fit perfectly, stays in place even through the dishwasher

Fir my 40 oz hydroflask perfectly. The color is an exact match to the color of my tumbler.

you WILL drop your hydroflask. you WILL knock it across your desk. do yourself a favor and grab this boot so you wont scream when you knock it off the trunk of your car and chip the paint on your first day using it.thick, well made, color matches the same color of your bottles. easy to clean. worth it. i have one on every bottle and cup from hydoflask.

Great product, true to size and color.

Was disappointed that when I removed item from the vacuum sealed bag there were several creases in the silicon. I waited a week hoping they would come out but they didn't. I needed up returning the item.

No more dents and clanging metal! Easy to clean
