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 traveller'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 hydrophobic down and DWR finishes are Non-PFC.
UltraDry Down:
The down is RDS-certified responsibly sourced. The non-PFC Ultra-Dry Down™ hydrophobic treatment means it absorbs less water than untreated down and dries much more quickly. Ultra-Dry Down does not affect the loft or lifespan of the down, or its breathability. The treatment will last through at least 20 washings
Non-PFC DWR Shell fabric:
Despite being incredibly lightweight, the 10 Denier UL Nylon is down-proof and surprisingly durable. A non-PFC DWR finish helps the shell to shed external moisture. This fabric is part of the secret to making the Spark and Flame Down Sleeping Bags and the Ember Quilt Series some of the lightest, most packable sleep system products available today.

Frequently Asked questions
Be used in cooler temperatures?
Only with the addition of a Reactor Thermal Liner. The Traveller -1°C paired with a Reactor would take this down to a couple of degrees below freezing. Realistically we recommend one of our cold weather sleeping bags for colder conditions.
Zip to another Traveller?
Yes. All Travellers have left zippers; to couple two together simply turn one of the two inside out.
Be used as a sleeping bag liner?
Yes. You could use the Traveller -1°C, or even the 10°C to boost the performance of a bag for cold-weather use. Adding one of these to a -6°C bag might make more sense than buying a -12°C bag for occasional winter use.
