1) Marmot Lithium sleeping bag (0 deg)
Kept me warm in a September snowstorm in the High Sierra. For women, a 20 deg bag just doesn't cut it above 10,000 ft -- reluctantly sold my Western Mountaineering Ultralite in order to buy the Lithium, because I froze using it on the JMT.... But it was worth it.
(y'all need more women as gear reviewers!)
2) Granite Gear Ozone backpack
Lightweight with great support, and can handle up to 40 lbs. Fantastic for thru-hiking.
3) Leki Ultralite Ti Air Ergo poles
Saved my knees when going downhill!!
