G'day Pat,

You should be ok with the Comfort Light Sleeping Mat over summer, however, if you're using the mat in spring or summer we'd recommend an insulated mat with an R-value over 2. It would be worth having a read of this article which explains R-values, and how to maximise your entire sleep system.

G'day Fiona, 

The Sea to Summit Comfort Light Sleeping Mat doesn't come with a pump, you can inflate it with your breath - but for ease of use we would recommend using a pump. 

Two compatible options you may want to check out are the Jet Stream Pump Sack  or the Air Stream Dry Sack both from Sea to Summit. 

Hi Fiona, 

I've just checked with the info provided by Sea to Summit, and it says that the Comfort Light (non-insulated) mat in the Small, Medium, and Large size will fit in the Jet Stream Pump Sack.
