Sleeping bag Traveler TrI/TrII Sea To Summit

The thermal performance of the Traveler Tr sleeping bag according to EN13537:

The EN13537 standard defines three temperatures, "Comfort", "Lower Limit", and "Extreme" in order to evaluate the thermal performance of a sleeping bag. This standard makes it possible to compare the different models on the market and to help the user in his choice.

- Comfort temperature:

This temperature corresponds to the temperature of use for which one expects to sleep relaxed.
If you are chilly or a woman, use this size to choose the model.

- Lower Limit temperature:

This is the temperature at which a standard human can sleep for eight hours in a curled up position without waking up.
If you consider yourself a high body temperature sleeper, use this value to gauge the coldest temperature the bag can be subjected to.

- Extreme temperature

This is the extreme survival temperature. Between the "Lower Limit" and "Extreme" temperatures, a strong feeling of cold is felt and there may be a health risk (hypothermia). For normal use, the manufacturer does not recommend using the bag under these environmental conditions.

Technologies used:

• Zip Coupling system



Sea To Summit sleeping bags feature the Zip Coupling System (YKK #5) with a 165cm zipper.
This system allows the bags to be coupled together, side by side, with each person sleeping in their own bag in order to best benefit from the insulation zones of the hood and at the level of the feet.



• Isolation 750+ Loft



The Loft is a size that evaluates the insulation performance/weight of a down. The higher this size, the lighter the down will be for equivalent insulation or the more insulating the down will be for an equivalent weight.
In other words, this size represents the quality of the down.
Each Sea To Summit down is certified by one of the largest laboratories in the down and feather industry, the Down Feather Laboratory (IDFL)


• Traitement hydrofuge Ultra-Dry Down

The Ultra-Dry Down Sea To Summit treatment reduces the negative effects of humidity on the down.
It protects the down from external humidity and condensation inside the sleeping bag.



• Responsible Down Standard (RDS)



The RDS standard helps to move the entire down and feather industry towards breeding practices that respect animal welfare. The standard requires independent, third-party assessments of all aspects of animal husbandry and treatment throughout the supply chain.
Sea To Summit ensures that each phase of the collection process is conducted with consideration for the welfare and ethical treatment of geese.
