And here is what Salsa has to say:
The EXP Series Full Suspension Frame Packs create storage capacity in the main triangle of your frame, keeping weight centered, and gear out of the way of off-road obstacles. They’re built with extremely durable fabric and zippers, and the result will see you through many miles, and many adventures. These framepacks are designed to fit specific Salsa suspension frames perfectly. Check the EXP Framepack Sizing Chart for fit information.
