Medium-Plus Dry Bag
28 reviewsPerfect size for my 40-degree sleeping bag and the clothes I sleep in. Fits perfectly into the Arc Blast sideways. I love how all of the Zpack bags keep my Arc Blast organized and tight to my back, and I never have to worry about anything getting wet!!

Keep your gear dry and dust-free without adding any more weight than you have to. This size will fit multiple clothing items or an average-sized ultralight sleeping bag. It fits well horizontally in most backpacks.

- Constructed from black 1.0 oz/sqyd Dyneema® Composite Fabric which is inherently waterproof and abrasion resistant. By comparison our regular Stuff Sacks are made from thinner .55 oz/sqyd material.
- Fully taped seams. Our dry bags will keep water out in typical backpacking conditions where the bag is not submerged.
- The top of the bags seal with stiff velcro to make closing and rolling the top easy! Air can escape from the rolled velcro, allowing these to squish flatter in your backpack as more gear is piled on top.
- Also check out our Zip Pouches for water and abrasion protection for your smaller items like your wallet, camera, phone, passport, glasses, etc.
- All Zpacks gear has a two year limited warranty against defects in materials or workmanship. Please see our return / warranty policy.
- Made in the USA.

Light & Weak
I purchased this to use as a stuff sack for my sleeping bag on a bikepacking tour of the Colorado Trail. Despite packing it gently and keeping it insulated from any rub spots on my setup, the bag split within the first few days of use, essentially tearing apart in multiple locations. I did my best to field repair it, but ultimately the fabric just couldn’t hold up to having any sort of pressure inside it - seems it’s best used for loose items that don’t need to be compressed.

Hello Dario, I do apologize that your dry bag did not hold up. Your purchase carries a 2-year warranty, so please reach out to us at support@zpacks.com.

works beautifully
My down backpacking quilt for in this beautifully! Easy to use!

Held all my Clothes on CT
I needed something to organize my clothes. It's s pain digging through your pack looking for that pair of socks or rain jacket. I bought this and it fit my pack perfectly! No lost clothes, easy to stuff everything into, it was totally worth it for me!

I like them, use 1 as food bag,1 for clothes, 1 for sleeping bag, they stack nice in my pack, and the lightest l have found.

Dry Bag
5 star quality. Light and strong and super well made and fit very well in Zpacks packs. Would be even better if came in a random mix of colours so easier to identify particular dry bags in pack. However had to take a star off as very expensive for what they are (and a lot more so that a few years ago).

Small Dry Bag
Unbelievably light weight. Unbelievably strong. I use this for hikes, long backpacking trip, and for school. The range of uses is truly expansive.
– Hugh R., ★★★★★
Say goodbye to soggy gear after unexpected rainstorms. This small dry bag will fit a down jacket or a few small clothing items like socks and gloves. It is also good for corralling a handful of miscellaneous loose items.

Slim Dry Bag
It’s the perfect size to fit a 40 degree mummy bag. It fits in the Arc Blast nice and snug! Well made and is tough as nails! It’s nice to not have to worry about the sleeping bag if I get water in the pack.
– Lon W., ★★★★★
Keep your gear dry when the weather is wet! The slim size dry bag will fit well in smaller backpacks. It is a good size for lightweight clothes, miscellaneous loose items, or a summer quilt. It is also useful to store flat items like a book, maps, or documents in an average depth backpack.

Tall Dry Bag
Proper quality, waterproof, perfect size for a handlebar roll. Bikepacking bliss. Thanks Zpacks.
– Randall R., ★★★★★
Need a little more space for an extra long carry? This dry bag is long and skinny allowing it to be securely lashed to your pack’s base straps, or stored standing vertically in a side pocket. Put less critical items like your tent, sleeping pad, rain gear, today’s food, or town clothes on the outside. Keep your most precious gear like your down sleeping bag and warm clothes inside your backpack where it is more protected from the weather.

Medium Dry Bag
Very lightweight and compact. Roll top allows for flexible stowing options. All specs exactly as stated.
– Patrick M., ★★★★★
Trek through damp forests with confidence and dry gear. This is a good size for multiple clothing items, a tent, or a down quilt. This size fits well horizontally in most smaller backpacks.

Medium Pillow
Slept great this past weekend using it for the first time. I really like being able to control the firmness of the pillow by using the desired amount of extra clothing I’m carrying. And it’s a great waterproof stuff sack!
– Todd L., ★★★★★
We merged the comfort of a pillow with the utility of a dry sack to form this Medium Pillow. Identical in size to the Medium Dry Bag, our Medium Pillow features soft micro fleece sewn to one half of the interior. Simply flip the dry bag inside out (as shown) and fill it with your spare clothes and gear to use as a pillow!

Medium-Plus Pillow
It worked very well on a recent three day weekend trip. Just what I was looking for to help cut down on weight and also be multifunctional.

Big Dry Bag
I love this dry bag. I needed one for my handlebar harness while bikepacking. It’s perfect. I can fit my duplex, tent poles, stakes, sleeping pad and pillow in it. Zpacks isn’t just for backpacking!!!
– Andrew L., ★★★★★
Stop the elements from soaking your gear. The ‘Big’ size dry bag has extra space for bulky clothes or a larger sleeping bag. The girth will fit horizontally in deeper packs.

Large Rectangle Dry Bag
It’s tough and does everything you’d want. What more is there to say? Kept my stuff dry in record breaking rains in Arkansas on Eagle Rock Loop.
– Michael N., ★★★★★
Supersize your dry bag and protect your biggest pieces of gear from the elements. This size will fit a larger sleeping bag, a bunch of clothes, or any other soft bulky item. The rectangular shape fits well in all of our backpacks, either standing vertically or sideways depending on the pack volume. The wide opening makes it easier to dig through the bag and find what you need.

Big Food Bag
Awesome bag, tough as nails. Highly recommended.
– Dave B., ★★★★★
Our food bags are made from thicker 1.6 oz/sqyd Dyneema® Composite Fabric to stand up to the abuse of bear bagging and to resist abrasion from heavy, pointy food items. The fabric is strong enough to discourage most small rodents but should still be hung out of reach over night. The “Big” size food sack can hold about 3-4 days of food. It will fit into our Arc backpacks horizontally. If you need more space check out our Large Food Bag or our Bear Bag Kit.
Large Food Bag
Held 5 days of food easily. Could hold a lot more. Compacts down to size you are carrying. Love the ease of the roll top snap closure. Is so lightweight and sturdy. A simple luxury to make things flow best on trail.

Our food bags are made from thicker 1.6 oz/sqyd Dyneema® Composite Fabric to stand up to the abuse of bear bagging and to resist abrasion from heavy, pointy food items. The fabric is strong enough to discourage most small rodents but should still be hung out of reach over night.The “Large” size food sack can hold about 5-6 days of food.
The rectangular shape fits well in all of our backpacks, either standing vertically or sideways depending on the pack volume. The wide opening makes it easier to dig through the bag and find what you need.
This is also available as part of a Bear Bagging Kit with cord and a rock sack.
