Review on Roswheel Essentials 141466 Accessories Capacity by Chad Black

Attachment and Stability - 4 velcro straps, 1 each side in back and 2 in front that wrap around my rack and are long enough to fully attach and feel solid. Size fits my bike rack and seat. . I can probably slide it forward on the counter and it still fits under the seat. Bungee loops on top can be tightened around items. Shoulder strap in outside pocket with zip at bottom. Internal mesh pocket in top cap with flap. 4 Connection to my luggage rack is 13" x 5.5" and the distance between the seat and the front of the luggage rack is about 4.5".
