Sea to Summit tests its sleeping bags for their temperature rating using the ISO 23537 test protocol. This test gives two key ratings: Lower Limit and Comfort Rating.
Lower Limit: The lowest temperature at which a man should stay warm.
Comfort Rating: The lowest temperature at which a woman should stay warm.
Sea to Summit Women’s-specific sleeping bags are listed using the Comfort Rating. Unisex bags are listed using the Lower Rating. For example, if the bag is rated at Lower Limit of 14°F | -10°C and Comfort rating of 27°F | -3°C, it should keep a woman warm down to 27°F | -3°C and a man warm down to 14°F | -10°C, if they are wearing warm clothes and using a good sleeping pad.
Remember: These ratings are just guidelines. Movement, weather, and your gear setup can all affect how warm you actually stay.
Pro Tip: Think of your sleeping bag, pad, and liner as a system. If you expect 28°F | -2°C weather, choose a sleeping bag rated for 23°F | -5°C, use a sleeping pad with an R-Value of 3 or more, and add a liner for extra warmth.

Description
The Traveller Sleeping Bag is great for a summer yurt trip, El Camino pilgrimage, bike tour, or as a lightweight summer backpacking sleeping bag. It's also perfect for those times when you didn't think you had the room for a sleeping bag until the need arose, like impromptu couch surfing, finding yourself stuck at an airport or staying warm on an overnight ferry.
650+fill non-PFAS Ultra-Dry Down keeps you warm on cooler nights and a full length zipper allows for ventilation in warmer temperatures (and lets you couple two Travellers together).

The second highest-lofting down used in any of Sea to Summit’s sleeping bags or quilts. 650+ Fill Power indicates that one ounce (30g) of down will re-expand to over 650 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.

Sea to Summit sleeping bag fabrics and insulation are made without PFAS compounds. The non-PFAS DWR finish on the shell helps prevent the insulation from becoming damp if the bag comes into contact with mositure, such as tent wall condensation.
Ultra-Dry Down is a non-PFAS hydrophobic treatment that absorbs less moisture and dries more quickly. It 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 responsibly sourced.
Sea to Summit Dry Bags, Stuff Sacks and Compression Bags use a non-PFAS Durable Water Repellent finish to help shed water. Big River bags use a non-PFAS PU coating.

Frequently Asked questions
Is the Traveller warm enough for cold conditions?
You could extend the 7°C/45°F Traveller down by a few degrees with a Reactor, but - lacking a hood and baffled construction - that is not its intended use.
Can the Traveller be zipped to another sleeping bag?
Two 2024 Travellers can be zipped together (the zipper of a Traveller Long will extend beyond the zipper of a Traveller Regular). 2024 Travellers can not be zipped to pre-2024 Travellers.
What's the best use for a Traveller?
Travel, couch surfing, surviving airports, sleeping in refugios on the Camino, summer/fall hut trips and lightweight summer bike/backpack tours
