Learn how to fit and use the Upgrade Your Pack Bundle to keep your ultralight gear organized and comfortable on the trail.

Quick Answer

The Upgrade Your Pack Bundle includes two accessories that improve comfort and organization: the Air Flow SitLight for back support and a cushioned seat, and the Shock Compression Cord Set for securing gear externally. Here's how to install and use both.

Why This Bundle Works for Ultralight Hikers

The bundle pairs two practical accessories that complement each other without adding significant weight. The SitLight doubles as a sit pad and back support, while the cord set lets you lash gear to the outside of your pack when internal space is tight. Together, they help you stay organized and comfortable on longer hikes.

Step-by-Step Setup

1. Attach the SitLight to Your Pack: Slide the SitLight between your pack's back panel and your hipbelt. Position it so it rests against your lower back for added lumbar support. Tighten the hipbelt over the SitLight to hold it in place. Common mistake: placing the SitLight too high, which reduces back support and can cause discomfort.
2. Use the SitLight as a Seat: At camp, remove the SitLight from your pack and sit on it on the ground. It provides a dry, cushioned seat and protects your sleeping pad from punctures. Checkpoint: Keep the SitLight accessible by storing it in an outer pocket or on top of your pack for quick use during breaks.
3. Install the Shock Compression Cord Set: Thread the cord through the daisy chains or compression loops on your pack. Tie a simple knot at each end to secure it. Adjust the tension so it holds gear snugly without overcompressing your pack. Common mistake: over-tightening the cord, which can damage gear or restrict pack expansion.
4. Lash Gear to the Outside: Place items like a tent or sleeping pad against your pack, then crisscross the cord over them. Hook the cord ends onto the opposite side loops for a secure hold. Checkpoint: Test the tension by shaking your pack; gear should not shift during movement.
5. Fine-Tune for Comfort: Adjust the SitLight position and cord tension during your first hike. A well-placed SitLight reduces fatigue, and proper cord tension prevents gear from swaying. Takeaway: Spend a few minutes dialing in the setup at home before hitting the trail.
