## Description

Product description Esky Emergency Supplies Emergency Sleeping Bag 10000mAh Emergency Radio Emergency Radio Compact Pocket-size A Single Bag Weighs only 3.9oz, which is compact & portable.

Review: Handy in a pinch - Dancing in the rain! I bought two for my Alaska trip, I used one in Alaska to lay on my tent floor due to all the rain and condensation inside the tent. I wanted to keep my pack dry. Last year I went out for a sunset hike and I forgot my rain jacket. I ended up using the 2nd one. I kept this one, I let it dry out and put it back in my pack for another day. Durable, lightweight, perfect size for 1-2 people with good coverage. Could squeeze in 3 with minimal exposure. Open all the way up perfect for 3-4 people. Also can be used as a sleeping bag if needed.
Review: Great emergency blanket - So far they’ve performed well. I’m a bigger guy and they cover me well. I live in the Midwest where temperatures can drop into the negatives. Having emergency gear is critical. The bivvy bag is compact and easy to travel with.

### ⭐⭐⭐⭐⭐ Great emergency blanket

So far they’ve performed well. I’m a bigger guy and they cover me well. I live in the Midwest where temperatures can drop into the negatives. Having emergency gear is critical. The bivvy bag is compact and easy to travel with.

### ⭐⭐⭐⭐ Can't go wrong at $12.99 a four pack
*by H***J on June 9, 2025*

It's like crawling inside a giant mylar balloon. The material is thin, but seems strong enough to reuse multiple times. The seams and edges are reenforced and add structure to the bag shape. I only tested in a cool room, but it definitely took the chill off more effectively than a bedsheet which is comparable weight and thickness. Have yet to test in real conditions. I would say that for the money, it wouldn't hurt to put a few of these in your vehicle winter kit or bug out bag. I knocked off the star because the neat little storage sack is single use. The sack is great, but you'll never get the bag stuffed back into it once used.
