Besides having the most sensational name of the bunch, the Sexy Hotness bag seems to have the most fun, too. It has pockets, a draw-string hoodie, padded feet and full-length zippers on each side—plus one in the middle to allow for walking. It can be connected to an infinite number of Sexy Hotness friends. (See the video for reference.) The bag comes in two sizes (3.45, 3.85 pounds, respectively) and is insulated with synthetic fill. The company claims it’s rated down to 20 degrees—although it’s unclear if that’s solo or tandem. From Alite: “Zip two or more together and get snuggling, spooning, or sporking!” Yikes!

Meet the JakPak—part tent, part sleeping bag, part jacket, and totally unique. The design is based around a waterproof, breathable rain jacket that deploys into a combination sleeping bag/tent. You really have to watch the video to grasp the concept. Maybe more than once. The whole shebang weighs about three pounds and comes in three sizes, from S to XL. The detachable tent can also be used as a pack cover, and its fine mesh netting keeps even small no-see-ums out while “in the tent,” or can act as mosquito netting while on the go. JakPak.com.

After a whopping eight years in development, the Spoonbill double-bag is finally available for sale at your local gear shop. It’s already made a splash by picking up a 2012 Backpacker Editor's Choice Award, and weighing in less than plenty of single bags we’ve seen, it’s no wonder. The 2.7-pound bag uses 850-fill down insulation, and is also available as a 2.5-pound option with even warmer, 900-fill down. Don’t look for a temperature rating, though. The company says it’s hard enough gauging a rating for single bags. From the manufacturer: “The bag has 5 inches of loft which is what our standard 20-degree bags have, but with two people inside the warmth rating goes up significantly. This bag has been tested extensively on Denali for the past five years and the feedback has been that it is plenty warm on that mountain for the athletes who were using it.” Like all Feathered Friends bags, the Spoonbill is hand-made in Seattle, which partly explains the, ahem, lofty price tag.

If you think these colorful four-limbed sleeping bags look like some twisted take on the Teletubbies, you’re not alone. But don’t knock ‘em until you’ve tried one. This Classic model (representing the company’s fourth generation of product development), comes in three sizes, M, L and XL. The bag weighs between 4 and 4.7 pounds—so ultralighters need not apply. Made from Rip-Stop Nylon with a water-resistant finish, this “bag” is made for walking, lounging or snoozing comfortably in temperartures as low as 35 degrees. The Classic comes in lemon (shown), chilli pepper red, black or pink. It’s also available in a $99 “Lite” model or two kids sizes that sell for $50 each. SelkBagUSA.com
