The EN Rating scale is a scientific test to determine the warmth of a sleeping bag. The test produces a Lower rating (for male sleepers) and a Comfort rating (for female sleepers). Both are listed in the features table on the product page.
A unisex sleeping bag with a Lower limit of 14ºF means a man should be comfortable down to air temperatures of 14ºF. The same bag will also have a Comfort limit, in the realm of 27°F, so a woman would be comfortable down to an air temperature of 27ºF. These ratings require a sleeping mat with an R-Value appropriate for expected ground temperatures – without this, the sleeping bag itself is unlikely to keep the sleeper warm enough.
A variety of factors impact sleeping bag warmth - the above temperatures are merely guidelines, not guarantees. It’s important to think of a sleeping bag, an appropriately insulating sleeping pad and a liner as a sleep system. For example - if you plan on sleeping in nighttime air temperatures of 27ºF / -3°C, choose a bag with a gender-appropriate rating of 23°F / -5°C, plus a sleeping mat with an R-Value of 2.5 to 3, and consider a Reactor thermal liner.
Description
This aptly named sleeping bag and down blanket is the traveler's best friend. Whether you are on a summer bike tour, or a hut trip, or couch surfing, or simply stuck at an airport or ferry terminal, the Traveller unpacks from an almost impossibly small compression sack to reveal a rectangular sleeping bag which can also unzip to form a blanket.
Two different fill weights of 750+ loft RDS-certified ULTRA DRY Down are available: both models feature a drawcord foot box which cinches tight for warmth or opens for ventilation.
Lighter than some sleeping bag liners and just as compact, find out why the Traveller is the ideal companion on the road HERE

TECHNICAL FEATURES
This ultralight fabric composes the exterior and interior of the Ember quilts and the Traveller bags, and just the interior of the Spark series bags. While this fabric is light, it's quite durable and ensures easy packing and care for your bag or quilt.
The second highest-lofting down used in any of Sea to Summit’s sleeping bags or quilts. 750+ Fill Power indicates that one ounce (30g) of down will re-expand to over 750 cubic inches after compression. Higher loft means that less down can be used to achieve the same temperature rating – important for performance sleeping bags. The loft and down quality/composition are independently tested by the International Down and Feather Laboratory (IDFL) – a copy of the certification is supplied with every Sea to Summit sleeping bag. The down is responsibly sourced and RDS certified and treated with our non-PFC Ultra-Dry Down™ treatment.
100% of the down used in our sleeping bags and quilts is independently certified to the Responsible Down Standard (RDS). The RDS certifies down against animal welfare requirements and tracks it from the source to the final product. The purchase of RDS certified products demonstrates demand for better animal welfare practices in the down and feather supply chain. Sea to Summit is certified to the RDS.

Down and synthetic bags identified with our zip coupling symbol use a 65 inch #5 YKK full-length zip which allows a unisex left-handed and women's specific right-handed bag to pair together. Designed to pair side by side, each person sleeps in their own bag enabling each of you to take advantage of your bag's unique insulation zones, hood and footbox features - perfect for cozy adventures for two. Bags with full-length #5 YKK zips on both sides can also be coupled together with other pairing bags.
Sea to Summit sleeping bags do not contain PFCs.
Ultra-Dry Down™ uses a non-PFC hydrophobic treatment to ensure it absorbs less moisture and dries more quickly. The treatment does not affect the breathability or the lifespan of the down and lasts through at least 20 washings.
The down used in our sleeping bags is RDS-certified responsibly sourced.
Down and synthetic-insulated sleeping bags utilize a non-PFC DWR treatment on the shell fabric for external moisture repellency. This helps prevent the insulation from becoming damp if the sleeping bag comes into contact with condensation on a tent wall, for instance.

Frequently Asked questions
Is this sleeping bag warm enough for cooler temperatures?
This down sleeping bag is only warm enough in colder weather with the addition of a Reactor Thermal Sleeping Bag Liner. Pairing the Traveller 30°F a Reactor liner would keep you in comfortable in below freezing temps. For maximum protection, we recommend trying a sleeping bag specifically designed for colder conditions.
Can this sleeping bag be zipped to another sleeping bag?
Yes, this sleeping bag can be joined with another Traveller. All Travellers sleeping bags have left zippers; to couple two together simply turn one of the two inside out.
Can this sleeping bag be used as a liner inside another sleeping bag?
Yes. You could use the Traveller 30°F sleeping bag, or even the 50°F, as a liner to boost the performance of another bag in cold weather. For instance, adding one of these to a 20°F sleeping bag might make more sense than buying a 10°F bag for occasional winter use.
