Best Emergency Blankets: What to Look For | CritPro
CritPro on
Not every emergency blanket is a single-use foil sheet. Here is what packable insulated blankets do differently, what to look for, and the best options at CritPro.
When most people hear "emergency blanket," they picture the thin metallic sheet that comes folded into a first aid kit. Those have a real job, but they are a single-use, one-time-deployment tool. A different category of gear, the packable insulated blanket, covers a lot of the same ground while actually being something you would reach for on a normal camping trip, not just a worst-case scenario.
This guide focuses on that second category: reusable, packable, insulated blankets built to handle repeated outdoor use while still earning a permanent spot in a survival kit, vehicle kit, or pack.

Two Different Categories of Emergency Blanket
Single-use reflective (mylar) blankets
The familiar foil emergency blanket works by reflecting radiated body heat back toward the body through a metalized polyethylene film. It is inexpensive, extremely compact, and earns its place as a last-resort layer in a first aid kit or glove box. The tradeoff is durability and comfort. Mylar blankets tear easily, do not breathe, and are genuinely a one-time-use item in any real wind or activity. They are worth carrying as a cheap backup, but they are not something most people would reach for on a normal trip.
Packable insulated blankets
A packable insulated blanket like the Snugpak Jungle Blanket takes a different approach. Instead of reflecting heat off a foil surface, it traps heat in a lightweight synthetic fill the same way a sleeping bag does, while a windproof, water-repellent outer shell keeps the elements out. It compresses into a stuff sack a fraction of its expanded size, holds up to repeated use trip after trip, and works just as well thrown over your shoulders at a campfire as it does in an actual emergency. The tradeoff is size and weight compared to a foil sheet, though both remain small enough to live in a pack without becoming a burden.
What to Look for in a Packable Insulated Blanket
Insulation type
Synthetic insulation, like the Travelsoft fill used in the Snugpak Jungle Blanket, retains warmth even when damp and dries faster than natural fill, which matters for a blanket that may end up exposed to weather. Synthetic fill is also generally more affordable and more durable under repeated compression than down.
Packed size and weight
The entire point of this category is that it travels well. A blanket that compresses into a stuff sack roughly the size of a water bottle earns a permanent spot in a pack, vehicle, or kit. One that does not compress well tends to get left behind exactly when it would be useful.
Wind and water resistance
An outer shell that blocks wind and resists light moisture extends how this blanket can actually be used: around a campsite, over a sleeping bag, or as a layer between you and the wind on an exposed overlook, not just inside a dry tent.
Size: one person vs shared use
A standard-size blanket covers one adult comfortably. A larger size adds the option of sharing it with a second person, wrapping fully around someone seated, or simply having more material if you run larger or want extra coverage with room to spare.

Best Overall: Snugpak Jungle Blanket Olive Windproof Packable Blanket
The Snugpak Jungle Blanket is a warm, lightweight blanket built around Travelsoft insulation, the same type of high-loft synthetic fill technology Snugpak uses in its sleeping bags. At 64 by 76 inches, it covers one adult fully and compresses into an included stuff sack roughly the size of a water bottle, around 25 ounces packed. The windproof, water-repellent outer shell and antibacterial fabric treatment make it practical for repeated outdoor use rather than a single deployment, whether that is camping, a long drive, or an actual unplanned night outdoors.

Best for Two People or Extra Coverage: Snugpak Olive Jungle Blanket XL Travel Blanket
The Snugpak Jungle Blanket XL scales the same Travelsoft construction up to 90 by 72 inches, large enough to share between two people or to give one person substantial extra coverage. It uses the same windproof, water-repellent shell and antibacterial treatment as the standard size, with a slightly larger packed size to match the added material. For a vehicle kit, a base camp setup, or anyone who simply wants more blanket, the XL trades a small amount of pack space for meaningfully more coverage.

Quick Comparison Table
Where This Fits in a Survival Kit
A foil mylar blanket is still worth keeping as a near-weightless backup, and it is the right call for a minimal first aid kit where space is at an absolute premium. A packable insulated blanket like the Snugpak Jungle Blanket is the better choice as your primary shelter layer beyond a bare-minimum bivy, since it is something you will actually use on a normal trip rather than gear that sits untouched until the day you genuinely need it. Carrying both, a mylar blanket as a true last resort and a packable insulated blanket for everyday use, covers the full range of what an emergency shelter layer needs to do.

Frequently Asked Questions About Emergency Blankets
Is a packable blanket better than a mylar emergency blanket?
They serve different purposes. A mylar blanket is lighter, cheaper, and better as a true last-resort backup in a compact first aid kit. A packable insulated blanket is more comfortable, more durable, and useful on everyday trips, not just emergencies, which makes it more likely to actually be in your pack when you need warmth.
Can a packable insulated blanket get wet?
The water-repellent outer shell on a blanket like the Snugpak Jungle Blanket sheds light moisture and resists damp conditions, but it is not fully waterproof the way a rain shell is. The synthetic insulation continues to provide some warmth even if it does get damp, which is an advantage over down fill in wet conditions.
How small does a packable emergency blanket actually compress?
The standard Snugpak Jungle Blanket compresses into an included stuff sack roughly the size of a large water bottle, small enough to live permanently in a pack, vehicle console, or kit without taking up meaningful space.
Do I need the XL size or is the standard size enough?
The standard size comfortably covers one adult and is the right choice for most individual packs and kits. The XL is worth the extra pack space if you plan to share the blanket with another person, want significant extra coverage, or are outfitting a vehicle kit or base camp setup where space is less constrained.
Final Verdict: Best Emergency Blankets at CritPro
For most individual kits, the standard Snugpak Jungle Blanket is the right call: warm, windproof, genuinely packable, and useful on any normal trip rather than just a worst-case scenario. Step up to the XL if you want to share it with someone else or simply want more material to work with. Either way, pairing one with a lightweight mylar blanket as a near-weightless backup covers both ends of what an emergency shelter layer needs to do.
