Bivy

The Bivy Stick is the smallest piece of gear that can end a search. It pairs to your phone, runs on the Iridium network, and sends a real two-way message from places where your bars died hours ago. This is where we cover it: firmware updates, plan changes, how the SOS handoff to the 24/7 emergency response center actually works, and what the battery really does after three cold nights in a pack. If you carry one in a daypack or a glovebox, read this before you out, not after.
