Rated 5 out of 5 by from A Staple! My entire family has a hydroflask and we have had zero complaints. We are avid travelers and are exposed to different types of weather. This bottle keeps my water nice and cold! This is a staple as far as water bottles!

Rated 5 out of 5 by from Best of the best I Love hydro flask. This is my 4th one. Not because the break down, just because I love all the colors. Keeps hot or cold all day. It's the best, hands down.

Rated 5 out of 5 by from Durable & Reliable I've had an older version of this water bottle and it has survived my active college lifestyle. I've dropped it down steps, left it on top of my car (and drove away) and sat on the beach for hours. It always keeps my drinks cold and still looks great for all the wear and tear I've put on it! I just bought a new one in Kiwi for my moms birthday! Love the flexible top. Moosejaw's shipping was prompt and the packaging was great!

Rated 5 out of 5 by from Perfect For Travel and Day Hikes The 21 oz. Hydro Flask is perfect for the side pocket of my day pack. Just the right amount of water to weight ratio, and water stays ice cold all day. Powder coat finish has proven more durable than my off-brand insulated flask with enamel finish. I'm getting a second, larger size Hydro Flask soon for occasions when I'm not traveling light and want a larger volume of water, such as for outdoor work sites. I still wish Hydro Flask would make a flip-top lid where you push a button and the entire top would flip open for one-handed open-top chugging. I have a plastic Contigo water bottle with this lid style, and I like that best for hiking and for one-handed use while driving. I don't really like the sports cap (too hard to open), the straw lids, or the small opening flip lids which only open enough for drinking through a small hole. I like chugging from a wide open top, and though the standard flex lid that comes with this model allows that, it requires two hands to open. Other than that, Hydro Flask is best-of-class for design and durability. Highly recommended!

Rated 5 out of 5 by from Love this Flask This flask is the best! Ice takes over 24 hours to melt. I love that. The drinks are always ice cold and refreshing.

Are you able to put ice in the cup easily? How wide is the mouth opening?

Asked by: Ellieirwin
Thanks for the question! I actually have this Flask and I can for sure fit ice in there no problem. I measured the width of the mouth and it is approximately 1.75 inches. I hope this helps!
