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 this website.

Q. What do I do if I have a warranty issue?
A.Please contact the shop you purchased the sleeping bag from or the International distributor in your country as listed on contact webpage.

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.We source our sleeping bag components from locations all around the world including Eastern Europe, Asia and the USA. Our manufacturing operations are in China as our 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 we offer a Short bag which is ideal for women if you are under 170cm (5ft 7in) in height.

Q. It seems that Sea to Summit has created some very nice sleeping bags, however I do miss the subject about animal welfare on your website. The reason that I have some of your products is because of your outdoor ethics: Leave no trace. But I would be very disappointed if those ethics do not included the raw materials for your products and especially animal welfare.
A.Sea to Summit firmly believes in the humane treatment of animals regardless of circumstance. We do not use any down that has been 'live plucked'. All down supplied by our 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 our vendors operate in strict adherence to their own animal welfare policies, furthermore our down shipments are batch certified to guarantee that the down is harvested by appropriate means throughout the supply chain.

Q. How much are the sleeping bags and where can I buy them?
A.Please click on the contact button in the top row and contact the Distributor of your country for prices and your nearest stockist.

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. How important is the Nanoshell covering on a 0 degree bag? I am planning on climbing Mt Rainier - is condensation a problem inside of a tent when in alpine areas or with snow/winter camping?
A.Condensation depends on relative humidity which is 'relative' because the maximum amount of water vapour that air is able to hold varies according to temperature. This amount decreases with temperature, so for example in the evening when the air temperature naturally decreases, the relative humidity increases. If the air is humid enough and the temperature drops enough, relative humidity will reach100% or 'saturation point' or the 'dew point' resulting in the water vapour in air condensing and forming water droplets, usually seen as mist. Normally surfaces close to the ground - such as grass, will cool much more quickly than the surrounding air so it is typical to see water droplets or dew forming on these surfaces be they grass or your tent fly, even if no mist forms.

Inside your tent conditions are normally different to the outside depending on the amount of ventilation available, the heat generated by the occupants or their cooking and the water vapour given off by them - one body alone will over twelve hours give off up to 400 mls of water vapour! Typically in conditions common in cooler climes condensation will occur overnight on the inside of the tent fly and liner, this condensation can be minimised by keeping the inside of the tent very well ventilated. As temperatures get cooler or conditions more humid, the water lost through your skin during time in your sleeping bag will result in condensation forming on the inside of the outer shell of your sleeping bag. But increasing the ventilation in your bag isn't an option as it will simply leave you shivering, so what do you do?

The answer is you can only reduce it slightly and then manage it. One way of minimising the level of condensation is to have a shell made of very breathable fabric. However there is a limit, use a fabric that is too breathable and it will also be unable to stop down tendrils working their way through - it won't be down proof. Putting a vapour permeable membrane on the fabric to increase waterproofness to outside moisture will paradoxically, decrease the breathability and enhance condensation on the inside.

Once you have condensation on the inside of that outer layer, there normally is no way to avoid the insulation next to it getting wet or trapping that moisture - if that layer is down, it will absorb water and become limp and soggy losing most of its' ability to be an insulator. In good weather conditions you can manage this problem in the morning by airing your bag so that the moisture is driven off by the warmer temperatures and lower relative humidity. But if you are on an extended trip or have bad weather this may not be possible so progressively, your bag will get damper, heavier and less able to keep you warm and cosy. Even if the down in your bag is treated to repel water, the water will still be trapped around it and this will reduce the warmth of your bag.

Sea to Summits' innovative three dimensional hydrophobic matrix (the 3D Nanoshell system) stops this condensation from mixing with the down in your bag resulting in eliminating that internal moisture faster thereby ensuring optimum performance. It is the perfect system for conditions such as snow camping.
