Richwrote a review of Arundel Dual Seatbag on September 5, 2017
Familiarity: I returned this product before using it
This unit does NOT hold a tube, no less anything else. And no attachments for lights. The attachment to the seat is not great. I sent it back and ordered a Silca and Jandd mountain wedge. The Jandd is larger and fits tube/CO2 x 2/tools and has slot for money. Good attachment. The silca is smaller if you want minimalist but fits tube/CO2 x 2/tools(comes with tools). Great attachment.
