The generously sized and ultra-versatile Basecamp™ options are also available in a synthetic version. This is an excellent choice when price and easy care are key considerations. These sleeping bags have the same generous rectangular shape and versatile design as the down version. They are insulated with Thermolite® that is built into the bags using a unique Wave Loft construction and helps retain warmth. The inner fabric is a soft, luxurious polyester that feels like silk for sleep-filled comfort. With multiple zippers, the Basecamp™ allows you to cozy up to your partner by zipping bags together, vent when it gets too hot, or remove the top entirely to use as a camping quilt or blanket. The Basecamp™ models have been designed to work with a sleeping mat and pillow to create a comprehensive sleep system you can really get comfortable with.
