Marmot Ultra Elite 20 is a sleeping bag for camping and summer excursions. The padding is a mix of three synthetic fibers which, when put together, offer good insulation but at the same time appear to be very light and very compressible. The result is therefore a perfect and very high quality sleeping bag to put in the backpack in the summer both for planned excursions but also for impromptu days! The outer fabric is a mini ripstop nylon, light but particularly resistant to tearing and abrasion. Its shape is a mummy shape that turns out to be very enveloping on the body: it will sleep really well! Marmot Ultra Elite 20 sleeping bag
