Blackburn Airstik SL Pump

Blackburn Airstik SL Pump Black One Size. Mini-pumps generally dont pump well, but full-size pumps are cumbersome. Blackburn, however, may be the first to conquer the mini-pump curse with the Airstik SL Pump. The Airstik SL offers a 93mm pump stroke while delivering 1.8 cubic inches of air per stroke--and if that means nothing to you, well just tell you its a lot of air for a short movement. And its definitely not too shabby for a pump weighing just 58 grams and measuring only 157mm long when closed. Lets face it, pumps are a necessary evilbut if you have to carry one, you should carry one that works well.
