G'day Amanda,

Yes, you can add a little bit of extra air to these mats if you prefer a firmer mattress. The stuff sack doubles as a pump, so you can use that to add a little extra air.

Hi Franco, we got very little information form Black Wolf on these mats, so had to wait for all the stock to arrive and measure ourselves. 

That being said, we weren't quite right with this one and we have since updated it. The box that the mat is packed in measures 82cm length and 26cm width and height, so you are right in that the packed length is a little longer than the inflated width.

G'day Adam,

I've just double-checked and yes the HexTherm 3D have square edges which are similar to the Exped and Zempire. 

G'day Rosy,

The Hexatherm 3D Single and the Megamat 10LXW are pretty similar. Both mats are essentially the same size and shape (with a 1cm variation). The fabric on the top is slightly different, with the Exped being a little softer to touch, and the Hexatherm 3D being a slightly higher denier. The overall weight of the Hexatherm 3D is a slightly higher, and it's R-value is slightly lower, so if you camp in winter this might impact, however, in general, the two mats are quite similar, with the Exped mat being a strong seller in the market for the past 10 years, and the Black Wolf a newly designed competitor.
