NanoLite – Ultralight Quilt for Warm Weather Adventures

The NanoLite is an ultralight quilt for warm weather designed for minimalist backpackers, fastpackers, and summer thru-hikers who count every ounce. Weighing just 14 oz, this streamlined sleep system delivers packable insulation without bulk, making it a favorite for warm nights on the trail.

Filled with premium 850+ fill power goose down, the NanoLite offers efficient loft and warmth, while the closed footbox helps trap heat where you need it most. Whether you’re cowboy camping beneath the stars or paired with a tarp shelter, this quilt provides cozy coverage with unrestricted movement.

The 12-denier ripstop nylon shell is breathable and lightweight, striking a balance between durability and minimalism. For maximum warmth and draft protection, the quilt includes an elastic pad attachment system that keeps it securely in place without limiting your sleep position.

The NanoLite is available in two lengths—5’8″ (fits users up to 6′) and 6’4″ (fits users up to 6’6″)—to ensure an efficient fit. For optimal comfort, we recommend pairing it with an R-4 or higher insulated sleeping pad.

When you’re focused on fast miles, small packs, and simple living, the NanoLite delivers reliable, no-fuss performance in a tiny footprint. It’s the ideal choice for summer trails, low-elevation trips, or ultralight thru-hikes where weight savings are essential but warmth still matters.

Handcrafted in the USA with ethically sourced down and Western Mountaineering’s trusted quality, the NanoLite redefines what’s possible in an ultralight quilt.
