In terms of sleeping bags, Big Agnes also pursues lightweight, but does not sacrifice the warmth of the sleeping bag, the down content of each sleeping bag basically accounts for 60% of the total weight, considering the use, it also revolutionizes the moisture-proof mat and the sleeping bag into one, the moisture-proof mat can be directly stuffed into the special cabin at the bottom of the sleeping bag, so as to avoid the user from leaving the moisture-proof mat due to moving after sleeping.
 
Big Agnes' sleeping bags are divided into UL and SL, that is, ultra-light camping and lighter ultra-light camping series, and the latest launch is the 1101 series, which is a lightweight sleeping bag that is more suitable for three seasons, and the sleeping bags under all series are named after Colorado places to commemorate the development history and experience of local outdoor sports, and can be previewed and purchased on its official website.
 
The 1101 series is derived from the famous 1101 line, in the form of a traditional mummy sleeping bag, using a minimum of external stitching to connect the waterproof fabric, the main body uses layered offset quilting, positioning the filler, avoiding displacement and reducing thermal performance, the side drainage velvet can also prevent heat loss along the zipper, the open rope is easy to adjust the tightness with one hand, there are different temperature scales to choose from, and the unit price is about $200.
 
There are two types of sleeping bags under the UL and SL series, namely Traditional Mummy and REM Mummy, there is no difference between the two in basic form and workmanship, but in terms of down expansion, Traditional Mummy is 700, REM Mummy is 650, so they have different applicable environments, Traditional Mummy has better warmth and can be used in cold campsites, while REM Mummy is suitable for 0° above the temperature.
