Traveler TrI Sleeping Bag

The Sea to Summit Traveler TrI Sleeping Bag adapts to your preferred method of exploration. At a temperature rating of 50 F, its a perfect choice for summer camping, a liner in the colder spring and autumn weeks, and a year-round option for hostel hoppers or couch surfers extraordinaire. Its slightly tapered design reduces a bit of weight and bulk for those backpackers obsessed with lightweight logistics. The Traveler TrI is stuffed with 750+ loft Ultra-Dry Down, a water-repellent down that reduces the negative effects that moisture has on down by retaining 60% more loft and absorbing 30% less moisture compared to untreated down. If your travel buddy happens to share your taste in sleeping bags, then zip together your Travelers and enjoy an old-fashioned sleepover. Even when unzipped completely, a single large-sized bag can conveniently cover two people as a light comforter. When the mercury drops unexpectedly, cinch the foot and collar drawcord to maximize the bag's heat insulation. For the lazy campers out there, the bag can be entirely reversed on the tail end of multiple-day trips, just like your shirts before laundry day. Stuff the Traveler into its Ultra-Sil compression bag when traveling from site to site and stuff it into the laundry bag when you run out of sides to reverse.
