We have limited supply of our Hydration Bladders for replacement or if you want an additional bladder. Or use your own bladder. This is a great inexpensive replacement. The EXPLORER.O/URBAN model does not come with bladders.
If you buy together with the Adult Hydration Bladder, save $5. Discount automatically applies in checkout window.
Hydration Bladders can only be returned if all the seals are intact and the bladders have not been used. If you use it, you might as well keep it because we will charge you and throw it away. No one wants a used bladder.
