Gilbert rugby balls are uniquely designed to absorb impact and keep their shape from normal training and play by losing slight amounts of air from the ends. This means every ball should be re-inflated to the recommended PSI before each match or training session. This standard pump fits easily in most rugby bags to ensure balls are properly inflated before every use.
A little upset with this product. Although it's priced properly, it is somewhat poor quality. The needle it came with bent when I went to pump it the first time (definently get replacements with your purcase). It gets the job done, for sure, and if you want a cheap and easy throw-around pump then go for this one.
