    Look forward to sleeping.

    The Sea to Summit Traveller 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 Traveller 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 Travellers 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 Traveller 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.

    Sweet Bag!

    • Familiarity: I gave it as a gift but have feedback to share

    Feedback below:
    "This bag was super light and easy to pack as it easily compresses into the small bag it comes with. I took on a trip where nights were into the 40’s and was a bit chilly with just the sleeping bag. As a liner in colder temps its’ great! Excited to use on a warmer trip."

    Warm Desert Nights!

    • Familiarity: I've used it once or twice and have initial impressions

    These bags are so light and small when packed it is truly impressive. Like anything ultralight they are made as tough as possible without adding weight. They are definitely up to the standard of quality that I have come to expect from Sea to Summit. We picked up two so if needed my wife and i can zip them together for added warmth. I love the pull close footbox that helps keep my temperature regulated and makes it easy to cool off without opening the entire bag. Very pleased with and excited to have these in the UL backpacking arsenal.

    • Familiarity: I've used it several times

    the size of this bag blew my mind, I knew it would be small but I never imagined it would compress so much. Its incredibly light and so packable its become an essential for any trip I go on now; camping or not, it unzips to a pretty awesome blanket. Its extremely breathable, great for warm nights camping out and its kept me fairly warm all the way down to low 60's. My only complaint is the pull string ties don't stay cinched tight all night. Solid bag would definitely recommend this.

    The SMALLEST packsize ever

    • Familiarity: I've used it several times

    This a super ultra light bag, I was hesistant to get it because I wasn't sure if it would be useful... A little too warm for summer not warm enough for spring or fall at elevation. BUT if you are with another person and you dont mind a snuggle, you can zip two of these together which extends its 50 degree rating considerably. This is especially true if you have a nice lightweight merino base to sleep in. With the compression sack this thing is like a fat soda can. This creates a whole new realm of possibility for pack size and weight. I don't see to many reviews of Sea to Summit sleeping bags out there probably because they are only 2 or 3 years into manufacture but I own an Alpine II and it is the finest sleeping bag i've ever owned. I only wish I could afford a Micro II, now that looks like a weekend mountaineer's stuff of dreams. I also plan on using this as a liner next winter in my Alpine bag to extend its rating well below zero. The extra pack weight won't be a concern for car camping or using a pulk. Check out Sea to Summit bags! You won't be dissapointed! HINT please sponser me sea to summit reps if you see this wink wink ;)
