Buying Guide: Key Purchase Considerations
What size do you need? For solo hikers, larger blankets (84” x 64”) provide full-body coverage. For groups, consider smaller packs that still offer heat retention but fit more easily into kits.
How reflective should it be? Most reliable foil blankets reflect up to 90% of body heat. Higher reflectivity helps in cold conditions, while some may also reflect sunlight to reduce overheating in hot environments.
Durability and reusability matter. Some blankets are designed for repeated use in emergencies, while others are intended as single-use or limited-use items. Choose based on how frequently you expect to deploy them.
Portability and packing method. Look for blankets that fold compactly or come in a durable pouch. Individual packaging can simplify distribution in group settings.
Intended scenario. For backcountry trips, prefer lighter blankets; for home or vehicle emergency kits, bulk packs may be more economical and practical.
