In short
Good for
- A self-inflating mat for car camping and short walks to a campsite, with a roomier contour shape
- Side sleepers who want a 7 cm mat that has 12% more sleep area than a tapered mummy mat
Strengths
- 7 cm thick, self-inflating, with adjustable firmness
- 75D recycled polyester fabric (Sea to Summit)
- Side-loading stuff sack and XPEL valve for tighter rolls
Weaknesses
- Weighs 1,050 g and packs to 28 x 16 x 16 cm; Sea to Summit calls it a little heavy for backpacking
- Sea to Summit lists its best use as camping, car camping, hunting and paddling
- Regular is 183 x 56 cm, so taller sleepers need the 198 cm Large
