G'day Errol,

We wouldn't suggest trying to blow the Synmat 7LW by mouth as the moisture in your breath could cause some issues down the track. We're yet to have someone report that the internal hand pump fails, they're a pretty straight forward system that isn't likely to fail. If needed you can inflate it with an airbed style pump.

G'day Peter,

Thanks for getting in touch. It's hard to give an exact life expectancy on the Exped Synmat 7LW. I have a friend who has had one of these in the down version for approximately 7 years and it is still going well. I guess it will come down to how frequently the mat gets used, the conditions you're in and how well the mat is cared for. I would expect you should get a good life out of any mat that is well looked after.

G'day Glen,

There's not an official weight limit on the Exped Synmat 7LW Sleeping Mat. I'd think that weight wouldn't be an issue if you're sharing with your partner although width might be a bit of an issue for you. 

G'day Peter, 

You can't use the Sea to Summit pump sack with the Exped Synmat 7LW, nor can you use the Exped Pump. This mat has a pump inbuilt, which is just as effective as the separately sold Exped one if that helps.
