The Mountain Hardwear AC 2 Tent is a light 4-season shelter that packs down small so you can take it mountaineering, winter camping, and backpacking high in the alpine. Its ripstop fabric includes ruggedly waterproof coatings to ensure weather protection when it's snowing. The DAC Featherlite poles keep this tent at a slim three pounds, while Mountain Hardwear's non-stretchy poles sleeves—code named Evolution Tension Arch—ensure stability and weather protection. The front door takes up a full wall for ease of entry, and it has a mesh window to amplify airflow when the weather's more favorable. There are two more mesh windows for excelled ventilation whatever the weather's up to.
