AUTONOMOUS COLD-INJURY PROTECTION & Enhanced Dexterity.

FrostByte Defense Technologies engineers autonomous heated glove liners for warfighters in extreme arctic environments — continuously monitoring tissue temperature and activating targeted heating digit-by-digit before frostbite can take hold. No user interface. No guesswork.

The System

Built For
The Mission

Autonomous Emergency Heating

Heating activates automatically — digit-by-digit — only when tissue temperature signals frostbite risk. No user input. No distraction from the mission.

Two-Month Monitoring Battery

Embedded sensors run passively for up to two months on battery. Minimal RF footprint — fully compatible with operational environments.

Liner Form Factor — 37g Per Pair

Fits under any standard cold-weather glove. No external battery pack, no interface to manage in the field. Zero operator burden.

The Problem We Solve
By the time frostbite is painful,
the damage is already done.

FrostByte eliminates the gap between cold and catastrophic injury — monitoring, deciding, and acting before the warfighter ever knows they're at risk.
