The Atlas Rack Pack is a sleek and secure replacement for a seat pack. It sits lower on the bike, improving your center of gravity. Allows your dropper post to move unencumbered, and is locked in and stable on top of the rack of your choice. With four simple straps it installs with ease.

Like all OMM products the Atlas Rack Pack is secure, silent, and ready for any riding condition.

What Makes The Atlas Rack Pack So Special?

100% Waterproof

Made from TPU fabric with Hypalon reinforcements, fully welded seams, and a roll top enclosure. You can be fully confident that your gear will remain dry and protected, even if you don’t quite make that stream crossing.

9 Liter Capacity

Not all trip segments have resupply options. When you need room for some extra food and water the Atlas Rack Pack’s 9L capacity will be ready. The 9L capacity is measured while still rolling the closure three times.

Quick Stash Straps

A criss crossing bungee cord on top of the bag is ideal for a rain jacket or warm layer you want quick access to or that bag of salty chips you picked up at the last resupply.

No Floppy Bags Here!

The attachments straps secure the bag to the deck of the rack at four points to stop it from jostling around. The quick locking buckles make it simple and easy to install and remove.

Dropper Compatible

Moving your gear from a seat bag to our Deck Pack gives you full use of your dropper again. The front end of the bag is tapered to help with seat clearance, even on small frames.

Silence is Precious

We head out into wilderness to escape noise. We made sure that all contact points between the Atlas Rack Pack and rack are silent, secure, and strong. No more rattling, and clanging bags.

per usual – great quality product. I needed something better than strapping things down with bungee cords. this checks all the boxes and more. looks GREAT, fits the OMM rack beautifully

Beautiful bag that perfectly fits my old man mountain rack. Stoked to test it on my bikepacking trip though Colombia – where unpredictable whether is the only constant. This will keep everything dry!

I love this pack and oh my goodness does it stay put. It was the perfect size for an overnight trip, I got the Hemlock with the flip cages as well for the longer excursions. This thing is seriously secure. The angled back of the pack is great, left good clearance for my dropper post. Was able to slip my sandals under the top bungee, and they were still in the same exact spot after a bumpy 60 miles. Very solid construction. Cant wait to take it on longer adventures.

My first thought was that it’s tiny (it states the volume clearly, that’s on me) but I think what really strikes me was the opening is small compared to a dry bag. Makes it hard to stuff, but I think it needs to be this way to keep the footprint of the OMM rack deck.

Otherwise this thing is bomber. No sway. I was using a dry bag on the rack deck before and it would wobble no matter how snug I made the straps. This thing just stays put.

Still need to test the durability.
