Kelty Mistral Si Sleeping Pad

The Kelty Mistral SI is a self-inflating sleeping pad with an R-value of 4.7, putting it in three-season territory — enough insulation for spring, summer and autumn camping on cool ground, though not deep winter or snow. The pad itself weighs 1250 g, and Kelty states the packed weight in its stuff sack comes in under 3 lb (about 1.4 kg). At 186 cm long and 56 cm wide, it's sized to pair with a mummy-style sleeping bag rather than a wider rectangular one, and self-inflating foam-and-air construction means less lung effort at camp than a pure air pad, at the cost of some extra bulk and weight compared with ultralight inflatables. This suits car camping, backpacking where a bit of pack weight is an acceptable trade for R-value and setup ease, rather than gram-counting thru-hikes.
