What are the different types of sleeping bags?

Trekking Sleeping Bags are categorised into three different classifications.

1)    Trekking sleeping bags based on the temperature.

2)    Trekking sleeping bags based on the shape.

3)    And sleeping bags based on the material.

Trekking Sleeping Bags based on the temperature.

1. Summer Sleeping Bags

Summer Sleeping bags are designed to be lightweight and provide just enough warmth to provide you with a good night’s sleep. The temperature rating is suited for 15 -20 Degrees Celsius and over.

Because they are designed for use in the summer, summer trekking sleeping bags use less insulating fabric making them super lightweight.

These sleeping bags will also have full-length zippers running down the length of the sleeping bag which would allow you to open them up in the night in case it gets too hot.

Tip: If you’re primarily going to be using them in South India, we recommend a simple summer sleeping bag. Not only are they affordable, but they also are lightweight and can be easily packed and carried around.

2. Three Season Sleeping Bag

3 Season trekking Sleeping Bags are designed for use in temperature ranges from 0 degrees Celsius up to 15 degrees Celsius. They are not suitable for use in hot climates as you will end up sweating profusely. These 3 season sleeping bags are best suited for summers in the Himalayas and lower regions of Himalayas in winters. They are not suitable for use on expeditions.

They come with features like hoods and extra insulation to combat the cold. They will always use the mummy style design as they help you retain more heat inside. Look for a snug fit, if its too loose, the warm air generated by your body will escape and cold air could come in.

Trekking Sleeping Bags Based on the Shape

1. Rectangular

Almost all lightweight summer trekking sleeping bags are largely made in this shape or design. The rectangular trekking bag design allows more air circulation preventing you from sweating while you sleep inside them. The design also provides more space around your feet giving you enough room to move around.

2. Semi-Rectangular

Higher quality summer trekking sleeping bags usually come with a semi-rectangle design. This design is very similar to a rectangular design but the edges will be more rounded. This design helps trap more warm air inside the sleeping bag.  Sleeping bags with this design will be more suitable for climates with medium to chilly nights.

3. Mummy Shape

Mummy Style sleeping bags by Gipfel

Mummy shape sleeping bags are designed to be more tapered towards the feet and provide a snug fit from the torso down. This reduces air circulation and helps trap warm air which will keep you warm through the night. Mummy style trekking sleeping bags also have a cinch-able hood that protects your head and prevents warm from escaping from your head.

Sleeping bags based on the material

1. Down Sleeping Bags

Down sleeping bags are very similar to down jackets in terms of the material, coating and construction. Down trekking sleeping bags will be super soft but since they would be used in extremely cold climates, they might be bulky. Down sleeping bags will also be extremely breathable similar to down jackets. It is not practical to use down sleeping bags in warm temperatures.

2. Synthetic Sleeping Bags
