    Excited

    I first got close-up experience with soft flasks while crewing & pacing a friend and realized I had to get one to try. I always carry a bottle in addition to my water bladder for my drinkable calories/carbs and it's pretty awesome to not have to carry it in my hand, and not even have to pull it out for a drink. I'll be curious to see if the design is prone to mold after lots of sugary uses. Cheers.
