What is the most common type of baffling used in backpacking sleeping bags?

The most common type of baffling used in backpacking sleeping bags is shingle construction. This design features layers of insulation that overlap like shingles on a roof, which helps to minimize cold spots by ensuring that the insulation is evenly distributed. This method allows for better thermal efficiency, as the insulation fills the spaces effectively while also reducing the weight and bulk of the bag.

Shingle construction typically provides a good balance between warmth, packability, and comfort, making these sleeping bags popular among backpackers who need reliable gear for varying conditions. The overlapping layers ensure that warmth is retained without adding excessive weight, which is crucial for hikers concerned with carrying a manageable load.

Other baffling constructions, such as box construction, have their own advantages and are used in specific contexts. Box construction creates individual compartments that hold insulation in place, preventing movement but resulting in a bulkier design. Tubular construction utilizes a cylindrical shape to house insulation but may not be as effective in preventing cold spots. Lastly, flat construction does not employ any baffling, leading to less insulation efficiency in colder environments. Each type has its place in the market, but shingle construction remains the most common choice for the versatile needs of backpacking enthusiasts.
