Question: Is the bladder sold separately?
Document: This is my third speed bag from Title. I purchased the smallest one through Amazon (size 5) which came in a tan/brown color. The bag itself actually measures about 5 1/2" wide x 8 1/2" tall when fully inflated. It features a 3" lace up side slit to access the bladder of the speed bag if need be.
the bag appeared to be a little lopsided, but will take shape as it is used. Leather is good and light
shipping was fast and product was as it was described in the description. Will purchase again when I need it. best bag I have found so far
rugged
great speed bag definitely recommend it to anyone! !
Wow,i had my tracking # the day after i ordered,and received my bag 3 days later.Great product,price,company! !
Very well made. I purchased after ready reviews and I am very y satisfied with the bag size and quality.
Very pleased with this brand. Speed bag exceeds expectations. It handles well being inflated then deflated when used. Recommended for all.
Very good quality. Was looking for a larger bag to practice new skills on. Construction is good, holds air very well.
This is overall one of the best bags I've used and have found it to be worth every penny.
