The Torchlight provides an innovative design to give you a customised fit for more comfort and a good nights sleep. This lightweight, high quality down sleeping bag will change the way side sleepers, wrigglers, and just about anyone else will enjoy a good nights sleep. 

Big Agnes says:

Ultralight, down fill traditional mummy bags with expandable panels for customized fit and enhanced comfort.

Designed for those gram-counting backpackers searching for the lightest gear with comfort in mind, the Torchlight UL Mummy bags feature all of the bells and whistles found in our Torchlight series. Two expandable panels from shoulders to footbox, increasing sleep space up to 10 extra inches! Depending on your sleep style and body shape, you can adjust the bag for customized comfort. This bag is insulated with 850 fill power DownTek™ water-repellent down, and baffle construction that provides more efficient heat distribution with zero heat loss, even when the bag is expanded.

Big Agnes' Torchlight UL 20 Down Sleeping Bag is a unique bag designed to offer maximum comfort through a customised and changeable fit. The main talking point with this design is the side zips which allow you to expand the bag at the top or bottom, or both to suit how you sleep. The zips allow the bag to expand significantly so you can get a lot more (up to 15cm extra) space if, like me, you're a side sleeper or you move around a lot during the night when camping. The impressive thing about this is there is no heat loss when the bag is expanded so they have clearly been able to insulate these areas really well.

The Torchlight uses really good quality 850 fill power, hydrophobic DownTek down for the insulation with the UL 30 having an impressive Comfort Limit of -7°C. The usual top quality fabrics have been used to keep weight to a minimum without compromising durability or warmth. The hood is a good snug fit and cinches easily to keep heat in. There is a nice, generous sized footbox and the length of the zipper means access is really easy, unlike many of the shorter length zippers used on other bags. The usual features have all been included to make this bag a joy to use.
