Being prepared for a day on trail is music to our ears. The Apex 20 was specifically designed to keep you comfortable while trekking with all day-hiking essentials you may need. The front of this pack features bungee cord that makes it easy to access & stow gear without losing a stride. Internal zippered pockets as well as a fleece-lined sunglass pocket make it a breeze to organize smaller items & electronics.

Comfort on trail is essential for any day spent in the backcountry. This pack features a no-contact breezeway created by separated lightweight EVA foam panels along a PE frame board keeping your back cool and refreshed all day long. A removable hip belt helps to stabilize the pack when needed, and conveniently stows away when you don’t. The Apex 20 has your back whether you’re hiking all day or just out for a quick jaunt in the woods.
