Lightweight sleeping comfort for vans, cabins, and warm summer nights

You don’t need a winter-ready bag for summer road trips or campgrounds with evening breezes. What you do need is lightweight insulation, soft materials, and a stuff sack that actually fits in your pack. The Kelty Mistral 40°F offers exactly that: comfort and reliability in warm weather, without overpacking your gear list or your budget.

Made for mild nights from spring to early fall

With a comfort range around 45–50°F (7–10 °C), the Mistral 40°F keeps you cozy on warm evenings—whether you're crashing in a tent, van, or hut. The synthetic CloudLoft™ ECO fill provides consistent warmth, even when damp, and dries quickly after humid nights or condensation.

—

Simple features that matter

Weighing around 2.6 to 2.9 lbs and packing down to just 9 inches in diameter, this bag is easy to stow and carry. The right-side zipper opens wide and resists snags thanks to a full-length draft tube. The contoured mummy shape offers thermal efficiency without restriction, and the footbox provides breathing room even on warmer nights.

—

Available in Regular & Long

Choose the Regular size if you're up to 6 ft tall, or go with Long for users up to 6'6". Both offer a practical, comfortable fit with enough room to shift positions or sleep in your favorite clothes.

Our take – Mistral 40°F at Campanions

The Mistral 40°F is what we reach for when temperatures are warm and weight still matters. It’s not made for subzero expeditions—and that’s exactly the point. For cabins, vans, summer hikes, or your favorite music festival, it’s the no-nonsense sleeping bag that gets it right when the weather’s on your side.

Campanions tip:

Regular is best for users up to 5'11" / 180 cm who prefer a snug fit for efficient warmth.
Long is great for taller sleepers or anyone who likes to stretch, change position, or keep gear/clothes inside the bag.

Not sure?
If you're close to the limit or sleep warm, go Regular.
If you move around or sleep hot and want space to vent—choose Long.
