Waterproofness is a standard feature across all four. The Ortlieb and Moosetracks share a strikingly similar diamond pattern and orange strap design, leading to speculation of one company copying the other.

Attachment and Stability

Attachment to the seatpost is crucial for stability. The Ortlieb uses a flat, smooth rubber attachment, the RockBros is similarly flat, while Moosetracks features a rounded, potentially less secure design. The reviewer highlights the importance of adequate clearance between the tire and the bag.

The reviewer successfully packed a sleeping bag, sleeping pad, tent, poles and rain fly into the Ortlieb.

Alternative: Bindle Rack

As an alternative, the reviewer considered a Bindle Rack by PDW, which allows for greater flexibility in bag choice. However, even with the Bindle Rack, there's a necessary tension adjustment, and the reviewer expressed concern about the long-term stability and security of this setup. The additional weight and complexity of the rack also need to be considered.
