Western Mountaineering Nanolite Quilt

The quilt relies on your sleeping pad to provide the necessary insulation underneath you. By eliminating the bottom fabric and fill, it reduces weight significantly while using the pad to trap heat, provided you use an appropriately rated sleeping pad for the conditions.

Yes, the Nanolite is specifically designed with a spacious cut that accommodates side sleepers well. Because it lacks the restrictive zippers and mummy-bag shape of traditional sleeping bags, you have more freedom to move and adjust your position throughout the night.

With a 38-degree Fahrenheit rating, this quilt is optimized for summer backpacking and mild-weather trips. It is designed to be a lightweight, packable layer rather than a four-season bag, making it perfect for warmer nights where you want to shed pack weight.

The Nanolite is designed to integrate with mummy-shaped sleeping pads to maintain a secure connection. This integration helps keep the quilt in place while you move, ensuring the edges stay tucked to prevent drafts.

The Nanolite has a maximum user height of 72 inches (6 feet). If you are taller than this, you may find the length insufficient to cover your head and feet comfortably, so we recommend considering a longer alternative.

It is highly compressible and packs down to a compact 6 by 10 inches. Given its minimal weight of just under 11 ounces, it is an excellent choice for ultralight setups where every cubic inch of pack space counts.
