So I needed a way to get my dachshund on the mountain bike trail with me, and the k9 sport sack air 2 is an awesome solution. Quality of craftsmanship and design is solid, he rides so well with no sway, and the pockets are perfect for his ball, his water, and a a few snacks. I wish the straps were a little longer as the sternum strap ends up rather close to my neck. So grateful though and we love it!! Thank you!!
