Buying Guide
I was freezing in the open wind. A thin Mylar blanket saved me. It was light, strong, and kept me warm.
I tested dozens of blankets. Some were bulky. Others broke fast.
Material:
Pick Mylar for emergency use. It’s light, thin, and holds up to 90–95% body heat.
Size:
A bigger blanket gives better coverage. Look for at least 80″ x 50″, especially if sharing or using it as shelter.
Weight and Packability:
Lighter blankets are easier to carry. Most weigh under 2 oz and fold to credit-card size.
Heat Retention:
Go for blankets that reflect body heat. 90%+ heat retention is best when you need warmth fast.
Waterproof and Windproof:
Choose blankets that stop rain and wind. You stay dry, warm, and calm in tough weather.
Durability:
Check if the blanket is tear-resistant. Some use anti-snag grids or thick PET material.
Multi-Use:
The best ones work as a blanket, tent, or shelter. Use them for camping, first aid, or hiking.
Pack Count:
Many come in packs of 4, 5, 10, or more. More packs help when you’re with friends or prepping for trips.
Reusable vs Single-Use:
Reusable blankets save money long-term. Some are easy to fold back and seal for next time.
Cotton vs Synthetic:
For home or bed use, cotton blankets feel soft and stay fresh. Use Mylar for heat emergencies.
GSM Rating (Cotton only):
A blanket with 350–400 GSM feels cozy but light. GSM shows how thick and warm the blanket is.
Pick what fits your needs. Stay warm. Stay ready.
