Jen Cwrote a review of Hydro Flask 21oz Standard Water Bottle with Sport Cap on February 13, 2018
Familiarity: I've put it through the wringer
I love all things Hydroflask, but this little bottle is a perfect size and a cooler color. I bought the kiwi as a gift since I use my big daddy flask all day every day, and now I think I have a friend for life in the recipient. Hydroflasks maintain temperature, are durable like your ol' Uncle Charlie who just won't die, and are easy to clean. Big love.
