Love this boot bag - it's super stylish but still does the job. In terms of height, it fits my tall boots (I am 5'7. Boots are 20'' at the tallest spot) and still has a few inches of clearance at the top. The side pocket is large enough to hold my spurs or some carrots but not long for a crop. The inside of the bag is also padded so I feel pretty confident my boots won't damage even leaving them in the car.
Overall, definitely worth the money!
Love the new boot bag! Looks amazing with the backpack!
