G'day Jeremy, 

I've just had a look at Sea to Summit's website, and it says this about storing their mats: All air mats should be stored with the valve open. Do not store the mat inside its stuff sack, and ensure the mat is completely dry before storage. To allow the greatest chance for ventilation the mat should be stored flat, folded as few times as possible. You can read more about that here, I hope that helps, Jeremy. 

G'day Annette,

The Sea to Summit sleeping mat range is all gradually being upgraded to include a pump sack. At the moment we still have a bit of a mixed bag though, but our website should let you know what each model/size is coming with, in the description. We've listed each item as either having a "pump integrated into stuff sack" or "available separately". 

G'day Greg,

The Sea to Summit Comfort Plus Insulated Rectangular Mat is mirrored on top and bottom, so it doesn't really matter which way up you have it. To be very technically correct though, the printing and logo on the mat are on the topside. 

G'day Andrew,

We've got the message regarding the pumps on all of the Sea to Summit mats as they are currently transitioning the model to include the integrated pump sack. At this point in time both sizes of the Comfort Plus Insulated Rectangular require the purchase of an additional pump.

G'day Michael,

The Sea to Summit Comfort Plus Insulated Regular will work well with the Sea to Summit Base Camp BCIII. These are an excellent option for the cold weather.

G'day Sean,

Thie Sea to Summit Comfort Plus Insulated Rectangular Mat has not been specifically designed for colder climates, it just provides insulation from the ground whatever the temperature is – so you’ll be able to use it in all kinds of climates!
