External Backpack Attachment Guide: Lashing Gear the Right Way

Before you start clipping carabiners everywhere, memorize these three rules. They separate the pros from the people who call for rescue because they're exhausted.

• Center of Gravity is King: Heavy items (water, dense food, metal) go inside, close to your back. Only light, bulky items (pads, tents) go outside.

• Eliminate the 'Tick-Tock': If your gear swings when you turn, it's loose. Use compression straps to lock it down.

• Streamline Your Profile: Nothing should stick out wider than your shoulders. If it catches a branch on a narrow ridge, you could be pulled off balance.

Use our Pack Weight Calculator to see how external gear impacts your total base weight before you head out.

The gear landscape has shifted. The bulky, sewn-on PALS webbing of 2024 is largely gone, replaced by lighter, stronger interfaces. Here is what you are working with on modern packs.

1. Laser-Cut MOLLE / PALS

Older packs used heavy nylon strips sewn horizontally. Modern 2026 tactical and hiking packs use laser-cut slots directly in the fabric (usually a high-denier Cordura or composite). This reduces weight but requires specific clips.

• Best for: Small pouches, first aid kits, knife sheaths.

• Technique: Weave the strap through the pack slot, then the gear slot, then back through the pack. Snap it shut. No shortcuts.

2. Daisy Chains

These are the vertical loops running down the back of alpine packs. They are static and bombproof.

• Best for: Carabiners, ice tools, drying socks.

• Warning: Never use a single carabiner to hold something heavy that can swing. It will act like a hammer against your spine.

3. Tension & Compression Straps

The most underutilized tool. Most packs come with side straps meant to compress the bag. These are your primary lash points for long items like tent poles or trekking poles.

4. Bottom Loops (The 'Sleeping Pad' Zone)

Two loops at the base of the pack. If your pack doesn't have these, you can easily rig them using accessory cord.

Let's talk about the hard stuff. Anyone can clip a water bottle. But what about a griddle, a bear canister, or a tent that won't fit inside? Here is the method.

The 'X' Lashing Technique

This is the gold standard for securing flat or odd-shaped objects (like that griddle or a solar panel) to the back of a pack using a daisy chain or MOLLE points.

1. Anchor Top Left: Tie a piece of 3mm shock cord or a webbing strap to the top-left loop.

2. Cross Over: Run the cord diagonally across the object to the bottom-right loop.

3. Anchor Bottom Right: Loop it through and pull tight.

4. Cross Back: Run it diagonally up to the top-right loop, creating an 'X' over the object.

5. Lock it: Secure the final end. The tension of the 'X' prevents the object from sliding up or down.

The Side-Lash (Vertical Items)

For tent poles or fishing rods:

1. Base Pocket First: Put the bottom of the item in the pack's side water bottle pocket (wand pocket).

2. Mid-Point Strap: Run the pack's lower compression strap over the item.

3. Top-Point Strap: Cinch the upper compression strap tight.

Pro Tip: Check our Tent Capacity Finder to see if your shelter packs down small enough to avoid external lashing altogether.

Back in the day, we used paracord for everything. It stretches when wet and slips. Today, you should be using Nano-Grip Straps (similar to the old Voile straps but with a magnetic-assist buckle).

• Static Cord: Use Dyneema or Kevlar core cord for heavy loads. It has zero stretch.

• Shock Cord: Only for light jackets or foam pads. Never trust elastic with anything over 2 lbs.

• Webbing: The standard 1-inch nylon webbing is still the most reliable for heavy hauling. It doesn't freeze and holds a knot.

If you are planning a long haul, use the Trail Food Planner to ensure your internal volume decreases as you eat, allowing you to eventually move that external gear inside the pack.

Before you step on the trail, perform the Shake Test.

1. Pack everything up.

2. Lift the pack by the haul loop (top handle).

3. Shake it violently side-to-side.

If you hear clinking, something is loose. If the external gear flops, tighten it. If the pack tries to twist out of your hand, your weight distribution is off. Adjust until the pack moves as a single solid unit. Loose gear is lost gear.
