The Optimus Crux with Terra Weekend HE kit is the ultimate backcountry cooking solution for those that can't sacrifice weight or pack space. The entire kit, stove and pans weigh only 9.7 ounces yet the stove and a 4-oz. gas canister can fit neatly inside the 5.2" x 4.8" mess kit with the frying pan as a lid. If you don’t need the mess kit you can fit the stove in the concave space beneath your gas canister and hold it together with the included mesh cover. Where this kit lacks in size and weight it makes up with quality. The Optimus Crux stove can boil a liter of water in about 3 minutes and when you use it with the Terra Weekend HE (Heat Exchange) cook set, you can cut your boil time down by 20% with the unique heat exchange system beneath the sauce pan.
