The FITLY FLASK400 is the largest standalone bite-valve soft flask in the FITLY lineup -- 13.5 oz (400 ml) in an 8 x 4 inch body designed to go farther without stepping up to a hydration bladder. Shrink-as-you-drink TPU design keeps the flask compressing onto itself as you drink, eliminating sloshing, bouncing, and rattling. Fits FITLY running packs and the FITLY Flask Holder.
Noteworthy FLASK400 features include:
• 13.5 oz (400 ml) capacity, 8 x 4 in
• TPU construction, 100% BPA and PVC free
• Soft-bite valve with rigid cap ring for easy refill
• Freezer safe -- doubles as an ice pack on hot days
• Top-rack dishwasher safe
• Max temperature 122F
• Fits FITLY running packs and the FITLY Flask Holder
• Two colors: Blue and Black
What's the capacity of the FITLY FLASK400?

Will the FLASK400 fit my FITLY running pack?
Yes. The FLASK400 fits FITLY running packs and the FITLY Flask Holder. It is sized larger than the FLASK150/250/350, so verify fit in your preferred pocket before ordering.
Is the FLASK400 dishwasher safe?

Can I freeze the FLASK400?

The FLASK400 is the largest standalone bite-valve flask at 13.5 oz (400 ml). The FLASK500 holds 17 oz (500 ml) with a round-bottom shape built to load up for longer efforts. Both share the shrink-as-you-drink design and bite-valve mouthpiece.
