Big Agnes Sentinel 30 Degree Doublewide Sleeping Bag

Built especially for couples, the Big Agnes Sentinel 30 Degree Doublewide sleeping bag is insulated with lightweight, compressible, and water-resistant 650 fill DownTek insulation. It packs down smaller than most doublewide bags, making it an option for backpacking in mild temperatures or for family and car camping.

Down insulation has long been renowned for its compressible properties and efficiency in delivering an excellent warmth-to-weight ratio, but its shortcoming has been its susceptibility to the effects of moisture, losing much of its performance qualities when wet or damp. DownTek insulation utilizes nano technology and a proprietary application process to provide water-repellency and both anti-microbial and anti-bacterial protection without adding bulk or weight. The bag's durable polyester rip-stop shell fabric features a water repellent treatment that further protects the insulation. A polyester taffeta lining enhances interior comfort. Quilted construction helps to keep the insulation evenly distributed to eliminate dead spots.

In a traditional sleeping system, the bag lies on top of a sleeping pad. In this configuration, many people find themselves rolling off the pad at night. Not only that, but the insulation on the bottom of the bag is often compressed by the sleeper's weight and, once compressed, the fill loses most of its insulating properties. The Big Agnes System is different and joins the bag and the pad together. A Flex Pad Sleeve on the bottom of the bag accommodates pads of varying lengths, widths, and thicknesses and ensures that the pad stays beneath you. It also enables the pad to deliver warmth and it allows Big Agnes to save weight and bulk by only lightly insulating the bottom of the bag itself. You'll stay warm and you can roll and move comfortably during the night without ever worrying about slipping off of your pad.

The bag is designed to be used with any two 20"-25" wide Big Agnes sleeping pads (sold separately) or a single 40" doublewide pad with an R-value or suggested temperature range to match the bag's temperature rating. Other branded pads can also be used.

A double wide insulated ergonomic hood, draft tubes located along the length of the dual anti-snag zippers, and a draft collar combine to lock in heat and keep out cold air to enhance warmth and comfort. Built-in "barns" keep pillows (pillows not included) tucked securely beneath sleepers' heads and an integrated Free Range footbox provides ample wiggle room for feet and toes.

The Big Agnes Sentinel 30 Degree Doublewide fits up to 6' 0" and includes a stuff sack and a storage sack.
