Best Synthetic Sleeping Bags Buying Guide

Before choosing the best synthetic sleeping bag you should consider following options:

1. Temperature Rating: Synthetic bags are designed to perform in different temperature ranges. The letter/number rating on the bag tells you the temperature at which the down-alternative insulation will maintain its performance.

The first number tells you the lowest temperature the bag is designed to maintain insulating properties. The second number tells you the upper limit of the temperature range.

For example, a bag rated with a 20 degree Fahrenheit rating tells you that the bag is designed to insulate at temperatures of 20 degrees F or lower.

A bag with a 0 degree rating tells you the bag is designed to insulate at zero degrees F or lower.

Pay attention to the “first number” as it is the most important, as it tells you the temperature the bag is designed to maintain its insulating properties.

The zero degree rating tells you that the bag is designed for very cold conditions.

2. Fill Power: All synthetic bags are not created equal. The Fill Power rating tells you how efficient the insulation is at trapping air and keeping you warm. The higher the Fill Power rating, the more efficient the insulation.

The higher the Fill Power, the warmer the bag will be. Fill Power is important if you backpack in cold or changeable conditions.

3. Lofted Insulation: Lofted insulation refers to the thickness of insulation that a synthetic bag has.

You can think of synthetic insulation like down, but without all the disadvantages. Synthetic insulation is not affected by moisture and has a lower weight to warmth ratio.

The thicker the insulation, the warmer the bag will be. A higher loft means more dead air space, which means more warmth. You will want a higher loft if you backpack in cold or changeable conditions.

4. Warmth to Weight Ratio: All synthetic bags are not created equal. Some synthetic bags have higher Fill Power, loft and warmth to weight ratio, but weigh more than other bags with lower Fill Power, loft, and warmth to weight ratio.

You will want a synthetic bag that has a high Fill Power and loft, but that is not overly heavy.

5. Insulation Choices: There are synthetic bags with just one type of insulation to choose from. There are also synthetic bags that have multiple insulation types to choose from.

You can choose to use just one type of insulation, or you can layer two or more types of insulation to customize your warmth.

This is a nice feature, as you can use just one layer of insulation in mild conditions, but use two or more layers in extreme conditions.

6. Durability: Synthetic bags are not as delicate as down bags. Synthetic insulation is made from polyester fibers that are stronger than goose down.

But all synthetic bags are not created equal. Some synthetic bags are more durable than others. Look for a bag that uses stronger materials and higher quality stitching.

7. Cost: Synthetic bags are generally more affordable than their down counterparts. But all synthetic bags are not created equal. Some synthetic bags cost more than others.

You will generally pay more for a synthetic bag with a higher Fill Power and loft, a higher warmth to weight ratio, and that is more durable.
