These are a perfect fit for the leather drink holders for the baggers. I can't believe how well these worked for keeping my drink ice cold all day long.
I just had to share because they work so awesome. I got the 24oz orange.
Hydro flask

 

Nice, where did you pick them up at?

I use Klean Kanteen although the ones I have are not insulated. Klean Kanteen released some vacuum insulated versions here a while ago so I have been looking at upgrading. Their insulated wide mouth with cafe cap makes a great coffee cup which fits nicely in the drink holders too.

 

I might keep my coffee there but water will probably come close to boiling point on 100 plus degrees days. My insulated frozen bottle water on the handle bars barely stay cold until the next stop.

 

While not mounted externally, I keep a small insulated soft side lunch bag in my saddle bag or tour pack. I also always keep a couple of frozen plastic water bottles in my freezer. Before leaving for a ride, I usually toss a couple of refrigerator cold water bottles in the bag along with the 2 frozen bottles. The frozen bottles keep the non-frozen bottles cold. By the time those are gone, the frozen bottles have started to melt and I have ice water again. This method generally keeps me in cold water all day.

 

I got one of them holders but nothing stays cold by the time I stop for a drink...

 

Get the same kind of hydro flask that he has and it'll help a massive amount. Those things hold temps for a really long time.

 

Dicks sells them and also hydro flask website . Google it.

Trust me guys your drink will stay ice cold all day, even on hot days.

 

The bigger ones are awesome for beer.. ��

 

I like this one!

 

I believe REI also sells them.
