Gregory's Sula 24L Backpack is designed to be just the right size for day hikes. It has plenty of space for an extra layer, some food to fuel your adventure, 3 liters of water to keep you hydrated, and a few other odds and ends. Its low-profile design won't throw off your balance as you scramble and boulder hop to the summit, and it features VaporSpan Ventilation and EVAP Moisture-Wicking Technology to provide airflow and pull perspiration away from you. The harness features EVA foam to absorb shock and cushion your shoulders under the load of the pack, keeping you comfortable throughout your hike.
