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 weighs 1250 g including its stuff sack, which Kelty lists as a total weight of 2 lb 12 oz (1.25 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.
