Sea to Summit Traverse TvII - Thermolite Sleeping Bag - Long - Green

Whether you hike through snow to sleep in an alpine hut or camp out after a summer storm, the Traverse won’t let you down. The unique WaveLoft construction uses thick layers of THERMOLITE insulation looped together to gain extra loft and trap pockets of warm air, providing increased warmth in colder conditions. The baffle construction also eliminates the frustration of getting tangled in loose lining as all lining fabrics are attached to the shell fabric. 

Suggested use : Trekking/Hiking, Camping, Snow Camping, Ski Touring

Season Ratings : Spring/Autumn/Winter

The Free-Flow triple-zip design ensures your sleeping bag retains maximum warmth and efficiency when needed and multiple ventilation options when it’s not. The half zip on the right side of the bag provides freedom of movement for both arms, additional ventilation and means the top third of the bag can be folded down as a mini quilt. 

The full length, two-way left side zip and separate foot zip transforms the bag into a full quilt for when the mercury climbs higher than expected.

Q. What is the EN13537 Temperature Rating System?

A. This is the European standard for sleeping bag temperature ratings. Everyone sleeps differently; some people are very warm sleepers while others feel cold easily.

There are many factors that affect your warmth and comfort in a sleeping bag. An important factor is that you use a good insulating mat, so your body heat isn't drawn into the cold ground you are sleeping on. Other factors include your tent or shelter, gender and metabolism, clothing, sleeping bag liner, use of the hood and your daily calorie intake.

Although the EN13527 standard does not identify a single precise temperature a tested sleeping bag is suitable for, it does provide an industry standardised temperature range that a typical user can refer to as a guide for the conditions their bag will be most comfortable in.

The EN13537 standard provides three temperature levels to guide a consumer in their choice:

• Comfort: The temperature at which a standard woman can expect to sleep comfortably in a relaxed position. If you consider yourself a cold sleeper use this rating to decide the coldest temperature the sleeping bag is suitable for.
• Lower Limit: The temperature at which a standard man can sleep for eight hours in a curled position without waking. If you consider yourself a warm sleeper use this rating to decide the coldest temperature the sleeping bag is suitable for.
• Extreme: This is a survival only rating for a standard woman. Between the lower limit and the extreme rating a strong sensation of cold has to be expected and there is a risk of health damage due to hypothermia. This is an extreme survival rating only, we do not recommend you rely on this rating for general use.

Q. What colours do the sleeping bags come in?

A. The sleeping bags only come in one colour option for each series.

Q. How small do they compress down to (when in compression sack)?

A. Please refer to individual models for this information.

Q. What is the warranty on the bag?

A. Sea to Summit offers a lifetime guarantee on all products against manufacturing and material defects. This warranty does not cover wear and tear. Should a fault develop in your product due to manufacturing or a material defect, we will repair or replace it at our discretion. This warranty is offered to the original owner of the sleeping bag if proof of purchase can be provided.

We encourage you to register your sleeping bag on www.seatosummit.com.au/sleepingbags.

Q. What do I do if I have a warranty issue?

A. Please contact Travel Universe via the Online Help Centre.

Q. How do I look after my bag when it is not in use?

A. The best way to look after your sleeping bag is to air it out thoroughly after use, then store your sleeping bag in the mesh storage cell provided. Store in a clean dry place. Never store your sleeping bag if wet or damp. If you think your sleeping bag is damp air it out for as long as it takes to dry or tumble dry the sleeping bag in the cotton sack on a low heat or delicates setting.

Q. Where are the sleeping bags made?

A. Sea to Summit source their sleeping bag components from locations all around the world including Eastern Europe, Asia and the USA. The manufacturing operations are in China as the existing infrastructure allows us to best manage quality.

Q. Are you intending to make a women's bag?

A. No, but in both the Traverse and Trek series bags offer a short bag which is ideal for women if you are under 170 cm (5\'7) in height.

Q. It seems that Sea to Summit has created some very nice sleeping bags, what is their policy in animal welfare?

A. Sea to Summit firmly believes in the humane treatment of animals regardless of circumstance. They do not use any down that has been 'live plucked'. All down supplied by their vendors are from ducks and geese that are harvested for the meat industry, therefore the down and feathers are collected as a by-product. The down is collected after the birds have been processed and are no longer alive.

Sea to Summit routinely ensures their vendors operate in strict adherence to their own animal welfare policies, furthermore their down shipments are batch certified to guarantee that the down is harvested by appropriate means throughout the supply chain.

Q. My partner and I prefer to zip our sleeping bags together. I am 6\'3 and she is 5\'9. If we got two bags, a long and a regular, with opposing zippers, would the zippers be the same length and could they zip together properly?

A. The Alpine, Traverse and Trek bags are fitted with a fixed zip length for all sizes. These bags can be zippered together in any combination of model and size. The Micro series can be zipped together with other Micro's.

Q. What are the benefits of down fillings?

A. In a world of technical brilliance it is remarkable that the performance of certain natural products have not been surpassed. Despite advancements in modern fibre technology, down is still the best insulator warmth for weight. Down forms the lightweight undercoating of birds, insulating them in very cold environments.

The down in Sea to Summit sleeping bags is a by-product of the duck and goose meat industry. Like most natural products, down quality depends on many variables; predominantly the species, the feather content and the age. The best quality down is sourced from older birds, consisting of large plumes and clusters that create hundreds of thousands of tiny pockets, trapping body heat to provide unmatched insulation.

Not only does down have the best warmth to weight ratio, it is also the most durable sleeping bag insulation. If kept dry and occasionally washed using the recommended method, it will last a lifetime.

Q. What does "loft" mean?

A. Loft is a measure of volume for a given weight of down. It is used to describe the quality of down, relating directly to the insulating performance. High loft down is warmer for a given weight than low loft down. Higher lofting down will fill a larger volume of space for a given weight, as a result, less down weight is required to fill each baffle in a sleeping bag. This translates to a lighter sleeping bag.

The most common measure of loft is called Fill Power. 650 Fill Power implies that one ounce of this down will loft to fill a volume of 650 cubic inches. 850 Fill Power implies that one ounce of this down will loft to fill a volume of 850 cubic inches.
