Attach Sleeping Bag Outside Your Pack

Updated 2026

If you're carrying a sleeping bag on your RTW journey, you'll almost certainly strap it to the outside of your pack - it's too bulky to pack inside. This creates a vulnerability: your sleeping bag is now constantly exposed to wear, weather, and damage as your pack gets thrown into bus cargo holds, tossed onto boat decks, and dragged across hostel floors.

The issue: standard sleeping bag stuff sacks aren't designed for extended external wear. The included sack is typically made from thin nylon that degrades quickly under UV exposure, friction with surfaces, and the constant compression of being strapped to a pack.

The solution is straightforward but often overlooked: invest in a heavier-duty stuff sack to replace whatever came with your bag.

What makes a good travel stuff sack: thick, durable material (at least 1000D nylon or ballistic fabric). Double-stitched seams. Multiple compression straps rather than just drawstring closure. Look for stuff sacks designed specifically for extended travel rather than alpine climbing (climbers expect sacks to break down and replace frequently).

Decathlon makes excellent compression stuff sacks in the $15-25 range. ESBIT makes durable alternatives. Serious travel companies like Patagonia have pricey but genuinely excellent options. The investment is worth it - a $20 stuff sack might extend your sleeping bag's life by years.

How you attach the bag matters too. Use multiple compression straps - one at the top, one in the middle, one at the bottom. This distributes stress points rather than concentrating pressure in one location. Constant tension at one location will eventually rupture even durable material.

Place the packed bag against the back of your pack where it's less likely to catch on things as you walk through doorways or squeeze through tight spaces. Keep it away from sharp edges and corners of your pack that could puncture the fabric.

Protect against weather exposure. Even waterproof stuff sacks have limitations. Use rain covers over your entire packed bag during heavy rain or ocean spray. Without protection, water eventually penetrates fabric, and a wet sleeping bag is exponentially heavier and takes forever to dry.

Inspect your sleeping bag and sack regularly for damage. Small tears become massive problems if left untreated. Seam leakage is also common - keep seam sealer on hand and touch up weak points every couple of months. Most gear repair services can handle more serious damage but prevention is cheaper.

Alternatively, some travelers use a large dry bag as their sleeping bag storage. Waterproof, durable, and offers better protection than traditional stuff sacks. The tradeoff is bulk and weight.

What many RTW travelers discover through hard experience: the sleeping bag attachment system you create in week two of travel is often different from the one you'd designed before leaving. You learn what actually works through doing it. The first compression strap placement might chafe the bag wrong, or you realize you want easier access for night use. Adjust and iterate.

Bottom line: protect your sleeping bag aggressively. It's one of your most important pieces of gear and also one of the most exposed to damage. A sturdier stuff sack is cheap insurance against expensive gear failure.
