Because fighting HYDRA is harder than hot yoga.

Is your yoga class filled with droves of loyal HYDRA officers blasting you with disintegration beams??  NO!

Is your instructor's name Johann Schmidt? Does he wear a facial prosthetic to hide the ghastly red skull beneath?? OF COURSE NOT!!!!!!!

Because your yoga class is completely devoid a merciless, militaristic occupation, I MUST conclude that Captain America's regular schedule -- which specifically includes mitigating said militaristic occupations -- is far more intense than hot yoga.

So...Cap carries the Captain America Nalgene Kids 12oz Water Bottle in an effort to rehydrate between rapid-fire shield slinging (while holding the warrior pose for 79-minutes).

Made from durable, clear plastic, this 12oz Captain America water bottle for kids features -- first and foremost -- an image of Cap charging behind his very own logo.

Spinning it around, we see another image of Cap plus graduated markings assessing your fluid level (in milliliters).
