I've only used this pack a few times since I got it on Christmas. I purchased it specifically for a day hike/summit pack. It's super light, durable, packs down to nothing and is very simple to use. I'm very impressed with Arc'teryx and the quality of their gear. I would recommend this pack to anyone looking for a high quality lightweight pack for those day hikes or even a lightweight overnighter. So far it has exceeded my expectations.
