Small volume, zero pressure balloon systems for remote sensing activities in the upper atmosphere. A balloon system includes an air ingestion clip proximate the nadir fitting to inhibit air ingestion during ascent, the clip releasing to allow air expulsion at a predetermined altitude. Another balloon system includes a parachute system having inflation guards that inhibit the parachute from inflating when inverted during ascent and float, the guards releasing to allow parachute inflation during descent.
