Big Agnes’ Q-Core SL is a lightly insulated mat that, at 550g, offers an R-value of 4.5.
Inflated, it has the appearance and feel of a ‘car camping’ mat – it’s plush and comfortable. Softer air pressure suits a fully horizontal position, but for sitting or lounging it can be inflated to feel a bit harder.
The surface fabric is hardwearing and does not leave you paranoid about putting the mat down on rough ground, but its non-slip qualities could be better; I found myself sliding off the mat a bit on uneven terrain. The fact that the mat’s edged air- chambers are thicker than those in the middle mitigates this, and makes the mat more captive to sleep on.
This mat is lightly insulated, but its claimed R-value, which is high for a three-season mat, would allow it to be used in New Zealand winter conditions without additional insulation.
It comes with a mesh stuff sack, which is good for breathability when packing the mat if it’s damp. The stuff sack also has a pocket containing a field repair kit.
Overall, this mat offers a strong combination of comfort and durability for a reasonable weight, and makes a good do-it-all sleeping mat.
