A Quick Look into The Bivy Vs Sleeping Bag Argument.
Explaining the difference will be confusing unless you know each of them from a clear viewpoint. Let me walk you through their overview before getting into the second section.
The Bivy aka Bivouac bag is a literal bag (more like a comforter) that people use as a small teepee. It works great against water, dust, bug, and other small creatures who can disturb your sleep.
Mostly, the Bivy bag is made with solid nylon that can resist water in a good way. In case you are looking for one of the best Bivy sleeping bag, try the light and travel-friendly Go Time Gear Life Bivy Bag.

What Is the Difference Between Bivy and Sleeping Bag?
Now that you have a complete understanding of these two gears, I’ll just lift the veil about the contrasting things between sleeping bag liner vs Bivy in a short while.
If talking about their warmth and temperature rating, they might show dissimilar scores. As the Bivy is more like a shelter that most people use as a replacement for the tent. The warmth needed for freezing weather can’t be fulfilled with it.
Almost all Bivy bags might be able to increase warmth from 4° F to 8° F on average. In comparison to that, the sleeping bag would keep you hot more than anything by adding 5° F to 15° F warmth. Ensuring a large temperature rating for around 0° F to -20° F.
Summary: The sleeping bag provides better warmth than the Bivy bag.
The next thing that poles them apart is the purpose. In most user experiences, the Bivy bag would do a great job if used in neutral or warm weather.
Furthermore, Bivy is basically used in outdoor survival and camping emergencies. It is just a cover that grants protection against rain and basic obstacles excluding heavy snow. The Bivy bag work the same as a raincoat jacket which blocks heat inside but not like a sleeping bag.
On the other hand, the reason why people use sleeping bags is to sleep in a warm and enclosed area. It mostly traps your body heat inside to keep the environment heated.
However, there are a few sleeping bags that are rated to use in 4 seasons including summer, spring, winter, and autumn.
Summary: The Bivy bag is ideal for summer or spring while the sleeping bag stands on top for cold weather.
The weight of Bivy and the sleeping bag is pretty much different (unless the bag is down). Like everything else, the Bivy bag is super compact (small + portable) thanks to the tiny bag and stuffing capability to carry in the tiny sack.
This might not give a similar experience to the sleeping bag as it tends to be bulky due to insulation, fill power, and padding system.
However, the down sleeping bag is pretty light and travel-friendly (which most use for camping). Because the down bag is made out of goose feathers that don’t weigh as much as a synthetic bag.
Summary: The Bivy bag is light unlike the hefty sleeping bag (excluding the down bag).
