Know a pilot who seems to have everything? Just in time for the holidays, Free
Flight Day Packs are now available through the USHPHA Store! Made from recycled
paragliders, these bags are internally lined with cordura for extra strength.
With tough zippers and zipper pulls from paraglider lines, these bags are sturdy
and ready for adventure. Not to mention, 100% of proceeds are donated to the
Cloudbase Foundation!
