I’ve gone to a hydration pack recently and I love the single source and extra capacity of it. Most days it’s excellent and served me perfectly during the race the lake 2 years back.

Yesterday I was on a recreational ride and it was hot with high humidity. I made sure I was well hydrated and fueled. But I wonder if the backpack style isn’t reducing my body’s ability to cool by blocking airflow to my back.

Anyone else have this issue?

thank you
