The NEMO Persist Women's 45L All-Adventure Backpack is built for multi-day trekking and mountaineering, with a women-specific fit and 45 L of capacity at 1550 g (about 34 g per litre). The main compartment loads from the top but also opens via a side zip, so you can reach gear packed in the middle without unpacking everything from the top down — useful mid-trip when you need something buried under a few days' worth of food or layers.
Hip belt pockets keep small items like snacks or a phone within reach while walking, and removable compression straps let you cinch the load down as food and fuel get used up over a trip, or take them off to save weight on shorter outings. The CERO exterior fabric and CCubed back-panel cushioning are shared with other packs in NEMO's range, built for durability and back comfort under a loaded pack. At 45 L it suits multi-day trips of a few nights to a week rather than long thru-hikes needing more volume, or single-day outings where a smaller daypack would be lighter to carry.
