Mylar Emergency Sleeping Bag | Bivy Sack

Product Description:

Ultralight, waterproof emergency shelter that retains up to 90% of your body heat.

This reflective Mylar bivy sack unfolds to 84" x 36" — large enough for adults or children — and packs down small enough for a glove compartment, backpack, or bug-out bag.

• Wind & waterproof — shields against rain, snow, and cold exposure
• Full-body coverage — use as a sleeping bag or emergency blanket bivy
• Ultralight Mylar construction — strong enough for blizzard conditions, light enough to forget it's there
• Reusable — foldable and compact; inspect for tears before each use
• Bug-out bag essential — ideal for hiking, camping, car kits, and disaster preparedness

Note: Designed for emergency use. Not a replacement for insulated sleeping bags in extended extreme cold.
