This summer I have gotten into having a milkshake during or after I ride - milk, banana, PB, ice, and sometimes add whey and vit C.
I like to stick the shake in the freezer before riding to get it real cold.
an old water bottle I have lying around did not take kindly to milkshake use, so I have been using a plastic pint milk container from the grocery store. but that doesn't fit in my bottle cage.
ergo, I'm looking for a hydration bottle that:
1. can withstand the rigors of regular freezing and thawing
2. has some extra clearance around the spout for a thick milkshake
