GSI Outdoors made the Pinnacle Stove light and compact for ultralight backpacking and alpine climbing. Its high-efficiency burner balances between a fast boil time and reduced fuel usage, and the support arms fold down for compact storage. There's a control valve for micro-adjustments, and the four-season has a separated canister mount and folding legs that work particularly well on snowy grounds. GSI Outdoors included a bag, and ensured that the stove fits in GSI's nForm cookware supplies.
