OV compression dry bags

Love my OV dry bags, I thing I have three 20L bags plus the dopp and cube as well! I do a lot of travel and all my OV gear works perfect for that purpose. Currently writing this review from the port of Cadiz,Spain,we got here this morning 4/28/26. The dry bags for perfectly in my kotaUL travel backpack from OV making air travel and sea days hassle free.

Airtight pillow in a pinch

This bag holds air, and with the square bottom it forms into an a pillow that can be adjusted in size and loft/firmness. Filled with a fluffy jacket even better for comfort. I got this for my down quilt, and am sure it will keep it dry. Highly recommend. Photo shows bag with lofteck jacket inside.

20L Dry Bags

These dry bags weigh nothing, I use 1 dry bag for my food storage and bear hang, And I use the other for my clothes, sleeping bag liner, And pillow. I’ll probably get the smaller dry bag for my tent, You will find uses for these dry bags, Just get a couple and you’ll find out.

Designed to fill the bottom corners of backpack

The OV 20L compression dry bag is oblong/rectangular at the base rather than circular. This shape allows it to fill all four corners of the backpack without gaps.
It holds my quilt, sheet, sleeping pad, pillow, sleeping clothes, spares socks/undies, puffy jacket/beanie/gloves. It compresses well, leaving the rest of the pack with space for the tent and the Bearikade Weekender.

Love these bags

I’m never disappointed with OV gear. Like, ever. I waited for these to return to stock, then purchased two! I’ll buy more as I can. These are essential in my winter pack so I can find what I need without digging around in the cold.

20L dry bag

I first received one of these with a quilt I ordered and soon realized that I could also use this for extra clothes and as a food bag. Works great for all these. I don't use a pack liner so dry bags keep what needs to stay dry dry in my pack.

Great bag.

I buy this for my 0 top quilt.
So I can pack it smaller.
It works great. Thanks for all your great products. I use most of them daily.

Well Built

Haven’t gotten the opportunity to take them out much yet but from my initial experience they feel really solid. Bought two of them one for my clothing and sleeping bag, and the other for my bear hang. I was skeptical of how well these would be able to compress my synthetic sleeping bag but it was a non issue, did even better than a proper compression bag.
Really like OV’s performance oriented design approach.

Ultralight 20l dry bag

Ordered this for a 3day 2 night trip to test out before going on a long trial. Was very impressed with the quality of the the bag and it did exactly what I needed it for. Thanks for making great products. I enjoy knowing that if I spend my money with outdoor vitals I always get a product that exceeds my expectations. Thank you for all the hard work.

This sack rocks!

It’s very lightweight. Yet to be field tested by this outdoorsman, but they prompted me for a review immediately, so this is everything I can report. Cloud 9!

Super Effective

I used a couple of these to carry all of my own clothes and my wife's clothes in my KotaUL backpack for over a week in Greece. I had plenty of space for our gear & we had a great time!

Works great, compresses down wonderfully! Looking forward to hitting the trails soon.

Is this air permeable… as in allowing it to be compressed while roll-top closed?

Outdoor Vitals

No, you cannot seal the roll top while compressing. It is air/water proof. You need to compress then roll for best performance. Please reach out to support@outdoorvitals.com with any additional questions.

What is the purpose of "D" ring next to clasp on compression sack?

Outdoor Vitals

External Lash Point: It allows you to use a carabiner or cord to securely fasten the compression sack to the outside of a backpack or kayak.

Preventing Loss: It provides a place to clip the sack to a larger bag, ensuring it doesn't get lost, especially if used as a ditty bag for small items.

Bear Hanging: The D-ring can be used to tie off a rope for hoisting the sack into a tree (bear hang) to keep food away from animals.
