Recently found in an old mislabeled box, these Classic Style Pump Packs are vintage FastBack! In size Skinny or Standard, they are made to fit most common pumps, though the Skinny size might have trouble fitting hand pumps that aren't similarly small. Both sizes are 14.75in (37.5cm) long. The Standard Pack is 3.25" (8.25cm) wide and the Skinny Pack is 2.5" (6.35cm) wide. Comes with a pair of Annex Clips and two strips of Velcro.
