Iceflame Insulated Ultralight Down Quilt | NXT Series

One insulated ultralight quilt platform, four distinct ways to sleep. The Iceflame Insulated Ultralight Down Quilt NXT Series brings together a choice of down quilts for summer trips, three-season backpacking and colder camps—without the bulk of a conventional hooded sleeping bag. Choose the model first, then select the length, width and down-quality option that suits you.

Each model is a hoodless down quilt designed for adaptable temperature regulation: use it open when conditions are mild, or secure the foot end where that model provides it for a more enclosed sleep system. The existing specification images show the model-specific measurements, weights and temperature guidance.

Choose your NXT quilt

Model	Best for	What makes it different
Extra Quilt	Versatile backpacking and mountain use	The classic Extra Quilt NXT: a fully featured, customisable down quilt with a broad comfort range.
Extra Quilt Zip	When you want the warmest option in this range	Adds a zip along the back compared with the Extra Quilt, for a more enclosed setup and improved insulation.
Semi Quilt Summer	Warm-weather and lightweight hiking	The summer-focused option. Its foot-area zip can be closed to turn the quilt into a more sleeping-bag-like shape when temperatures fall.
Semi Qulit Mono	Spring, summer and autumn trips	An adaptable semi-quilt for three-season use, with a foot-area zip for a more enclosed setup when wanted.
