Learn how to pack your Pemi 15 for a fast hike. This guide covers gear selection, layering, and organization to keep you moving efficiently on the trail.

Quick answer

Pack your Pemi 15 by placing heavy items close to your back, using the vest-style pockets for frequent-access gear, and keeping your load under 15 liters for a balanced, fast-moving setup.

Why packing order matters in a low-volume pack

The Pemi 15 is a hybrid running vest with a low-volume design. Every cubic inch counts, and how you distribute weight affects your balance and comfort, especially when moving fast over uneven terrain. Placing dense items like a water filter or food bag against your spine prevents the pack from swaying.

Working with the vest-style pockets

The Pemi 15's front pockets are designed for quick access without stopping. Use them for items you reach for often: snacks, phone, map, or sunglasses. Avoid overstuffing them, which can pull the pack forward and restrict arm movement.

How to pack your Pemi 15 for a fast hike

Step 1: Layer your heaviest items against your back: Place your water bladder (if using), food bag, or extra layers in the main compartment so they sit flat against your spine. This centers the weight and minimizes sway. A common mistake is putting a soft item like a puffy jacket against your back, which lets heavier gear shift sideways.
Step 2: Fill the main compartment with medium-weight gear: Add your first-aid kit, headlamp, and any other mid-weight items on top of the heavy layer. Keep them organized in small stuff sacks so you can find them quickly. Avoid leaving empty air gaps—fill the volume evenly to prevent items from rattling.
Step 3: Stash light, bulky items at the bottom: Place your rain jacket or wind shell at the very bottom of the main compartment. These items are rarely needed in the first mile and won't affect balance. If you stuff the bottom too full, the pack may bulge outward and make the vest fit less snug.
Step 4: Load the front pockets with essentials: Use the vest-style pockets for your phone, snacks, map, and sunglasses. Distribute weight evenly between left and right sides. Overloading one side can cause the pack to twist on your shoulders.
Step 5: Secure loose straps and check fit: Tighten the sternum strap and side compression straps so the pack moves with your body. The Pemi 15 should feel like a second skin, not a bouncing load. A loose pack forces you to waste energy stabilizing it with your shoulders.
