THE VERDICT

The GSI Outdoors Pinnacle Four Season Stove is a very good four-season canister stove. It boils quickly when its partner windscreen is mounted, simmers well, and will hold larger pots. 

FULL REVIEW

The GSI Pinnacle 4 Season stove is one of two newly released entrances into the stove market for GSI. It’s a logical product line expansion for a company that makes so many practical camp kitchen products. This stove is a remote canister design, which can invert its canister when an extra boost is needed at low fuel volume or when the temps drop. I worked with this stove over a number of trips, including a week along the Pacific Crest Trail. It cooked as it should in all conditions, simmering steadily in high winds, with windscreen attached, and boiling when connected to a cold, exposed isobutane canister.  The GSI Pinnacle 4 Season stove boils fast when needed and packs comfortably in GSI’s nesting Dualist cooksets. It is best compared to the Primus Eta Spider.

Boil Time
The GSI Pinnacle 4 Season stove boiled two cups of cold tap water ten times at an average of 2:29 in sunny, calm conditions at 6,600 feet. This is faster than the Primus Eta Spider and Optimus Vega.

Wind Performance
In steady winds of 14.5 mph and gusts breaching 25, the Pinnacle 4 Season stove boiled five two-cup pots of cold tap water five times at an average of 2:47. The Pinnacle Windscreen was used.

Efficiency
The Pinnacle 4 Season stove used 2.5 ounces of Jetboil Jetpower fuel to boil ten two-cup pots of cold tap water. It is less efficient than the Eta Spider.

Cooking
The stove excelled in cooking tests, holding a 25-minute simmer in windy, wet conditions along the PCT. It didn’t scorch, cooked evenly under a small fry pan and allowed for multiple levels of control.

Weight
The GSI Pinnacle 4 Season stove weighs 5.5 ounces on its own. Packed in its carry bag, 5.9 ounces. The Pinnacle Windscreen and mounting plate add 2.8 ounces.
