Restrap Saddle Bag vs Salsa EXP Seatpack
Two seat packs, measured against each other on the figures that decide whether they work on a bike.
The short answer
The Saddle Bag takes capacity, how far it reaches back and tire clearance; the EXP Seatpack takes weight, price and value per litre. The biggest single gap is $67.99000000000001 between them. Which of those you care about depends on the frame you are fitting it to.

Where they differ
6 of the 6 things we can measure come out differently.
Capacity
1L more in the Saddle BagThe maker's own figure. Worth reading alongside the dimensions below rather than on its own — two bags of the same litreage can want very different frames.
Reach behind the saddle
4cm shorter on the Saddle BagLength is the lever arm on the seatpost, and the longer lever is what makes a loaded pack sway. Shorter is easier to live with; longer usually means more volume. It is a trade, not a fault.
Depth
2cm shallower on the Saddle BagDepth is what competes with the rear tire once the pack sags under load. On a small frame or a big tire this is the measurement that decides it.
Weight
135g lighter on the EXP SeatpackEmpty weight as published. Worth holding against capacity rather than alone — the lighter bag is not the better one if it carries a third less.
Price
$67.99000000000001 between themManufacturer's price as we hold it.
Per litre
$4.09 per litre between themPrice divided by the maker's capacity. A crude measure that still catches the case where the dearer bag is also the bigger one, which the price alone hides.
