It is EaZy pEaZy!
The Peazy is another step forward in the evolution of filling on the go. Featuring an M18 thread, the Peazy system can easily thread onto any small bottle. The Peazy couples with a bottle to be the perfect EDC fill accessory, giving you the ideal backpack fill complement. No longer are airgunners tied to a compressor or cumbersome fill tank located in their truck while in the field. The Peazy allows for the freedom to refill at the shooter's own leisure, freeing you to hunt at your own discretion. The Peazy features the same technology found in the famous EAzY Fill Trigger, with virtually no air wasted. Get your snowmobile/dirtbike/ e-bike warmed up, now you can take your air with you in your pack!
