MJ300 or MJ600?

The MJ Series gives you two options depending on how much insulation you want to carry.

MJ300 – A lighter option for milder camping conditions.

MJ600 – A warmer, more insulated option when temperatures drop.

Always compare the manufacturer's verified comfort and limit temperature ratings for each model with the conditions expected on your trip.

Mummy-Shaped Warmth

The tapered mummy design reduces excess interior space compared with a traditional rectangular sleeping bag.

That means less air around your body to warm while still providing comfortable coverage for a night outdoors.

Pair it with an appropriately insulated sleeping pad to create a more complete camping sleep system.

Important Use Information

Sleeping-bag temperature ratings should be interpreted carefully. Comfort, limit, and extreme ratings represent different conditions and should not be treated interchangeably.

Actual warmth depends on temperature, wind, humidity, shelter, sleeping pad insulation, clothing, individual metabolism, and other conditions.

For colder-weather camping, pair the sleeping bag with an appropriately rated insulated sleeping pad and other suitable cold-weather equipment.

Keep the sleeping bag away from open flames, heaters, stoves, sparks, and other high-heat sources. Dry thoroughly before extended storage.
