6. FLEXTAIL Zero Pump


The Zero Pump by FLEXTAIL is an ultra-compact air pump that makes inflating sleeping pads or other air-filled gear a breeze. Its small size belies its efficiency, significantly reducing the time and effort required to set up your sleeping area. It also functions as a vacuum pump, helping you compress your gear for even more space-saving. This version is FLEXTAIL’s most recent design - it is light as a feather, and compact enough to become part of an every-hike-carry. With the re-design, FLEXTAIL eliminated the flashlight capability, meaning all of the power stored in the battery will support filling your sleep pads, pillows, etc. The Zero Pump has a replaceable battery feature, allowing long-term outdoorsy folks to carry an extra battery in times of need. 

This version is the world’s smallest pump, and can pump up most sleeping pads around 25 times. It is highly portable and efficient, however, users must consider it’s compatibility with their sleep systems prior to purchase, as it is specifically designed for ultralight sleeping pads and camp pillows, which have comparatively lower air volume.

The Ultrafire knife appears to incorporate a ferro rod, not a flint. This is an important distinction that should be corrected in the review.
