Lets go...

If you’ve ever packed your quilt and thought…
“Do I really need a dry bag, or is a stuff sack enough?” — you’re not alone.

At Hilltop Packs, this is one of the most common questions we get from hikers dialing in their gear.

The short answer?
👉 It depends on how and where you hike.

But if you want the real answer (the one experienced backpackers use), let’s break it down.

What’s the Difference?

Stuff Sacks (Simple + Ultralight)

Stuff sacks are:

Lightweight
Flexible
Great for organization

They’re designed to hold and compress your quilt, while still being very weather resistant. You do have a small hole at the opening so they would not be great for being submerged.

👉 Most ultralight hikers use stuff sacks to:

Keep quilts contained
Separate gear inside their pack
Save weight
Still weather resistant.

💡 Important: Many experienced hikers skip compression entirely and just loosely pack their quilt at the bottom of their bag for better space use. If this is the path you take at least consider using a pack liner.

Dry Bags (Best Weather Resistant Protection)

Dry bags are:

Waterproof fabrics
Roll-top sealed
Seams are usually taped
Slightly heavier
Highly water-resistant designs

They’re designed to protect your quilt from rain, condensation, or wet gear.

👉 Backpackers use dry bags when:

Hiking in wet climates
Lots of river crossings
Boating is involved

💡 Down insulation loses warmth when wet, so keeping it dry is critical

So… Which Should You Use for a Quilt?

Here’s the real-world breakdown:

✅ Use a Stuff Sack if:

You hike in light weather
You use a pack liner already
You want the lightest possible setup
You prefer easier packing and access
easily compressible

👉 This is the ultralight crowd favorite

✅ Use a Dry Bag if:

You hike in heavy rain, extreme wet environments
You want extra peace of mind
Kayak, canoe or boating will be involved

👉 This is the “never risk it” setup

The Hybrid Setup (What Most Experienced Hikers Do)

This is the move most people settle on:

👉 Quilt inside a pack liner OR dry bag at the bottom of your pack

Bottom = quilt + sleep clothes
Middle = heavier gear
Top = things you need during the day

This keeps your most important gear:
✔ Protected
✔ Organized
✔ Easy to pack

What Size Bag Should You Use for Quilts?

This is where most people mess up.
