These bags are approximately three and five eights inches tall from base to bottom of ears with two rows of stitching. We've found that the newer stock styles roll around on top of single stitch bags for lack of contact and have a tendency to wiggle between the ears in three stitch bags. The two rows of stitching between the ears on these bags offer the shooter the best combination of contact and stability. Note: Sand is required to fill these bags. Mfg: Protektor
