Backpacker's Favorite—— Lightest Sleeping Bag in the World
2023-03-08A sleeping bag is a protective "bag" that people use to sleep. It is an object that can create an enclosed sleeping environment through zippers and other forms, as an alternative to people who do not have a bed to use. To some extent, it also has features of windproof, waterproof (and snowproof) and avoiding exposure. Together with the tent, it provides a better temporary rest environment for travelers.
Sleeping bags are developing in the direction of smaller and lighter storage area in terms of volume and weight in order to be easy to carry. The Spark SpI 40 is an ultralight sleeping bag that weighs 351.5 grams and is filled with 178.6 grams of down. This bag has a minimalist design and is designed for light and fast tasks.
Being light and natural has its drawbacks. We can only really use this thing in the summer because the EN 13537 rating lists a comfortable temperature of 48°F and a lower limit of 40°F. That is, it can withstand a minimum operating environment of 4.4°F.
The Spark SpI 40 is so lightweight that it is only as big as a liter of water after packing. As long as the temperature is suitable, travel enthusiasts can bring it along on any adventure.
