Ponderosa Panniers

Sold as a pair.

Where are you going? Absolutely anywhere with the Ponderosa Panniers. These bikepacking panniers are ready for everything. Sunshine or rain, your gear will stay dry and protected in these 100% waterproof, TPU fabric panniers with welded seams and Hypalon reinforcements.

We’ve secured them to the rack with velcro straps at the top that cam over the pannier rail and use the lower compression strap to loop through the rack and guarantee that your bags don’t turn into dumbo ears when you hit a bump, no matter how rough.

We’ve made all of the compression straps replaceable so next time you spill some salsa on your bag and Mr. Mouse nibbles through one you can just swap it out, nice and easy.

The Ponderosa Panniers have the typical frame sheet in the back (against the rack), but we’ve also added a removable frame sheet on the frontside of the bag so it compresses evenly to give you the slimmest profile bag possible with what you choose to carry.

Our branding is super subtle so you can focus on your adventure and not our logos. To add more options we’ve added loop velcro so you can attach any patch with ease and swap it out as your mood suits you.

100% Waterproof

Made from PFAS-free 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.

13L Capacity Per Bag

Not all trip segments have resupply options. When you need room for some extra food and water the Ponderosa Pannier’s 13L capacity will be ready. The 13L capacity is measured while still rolling the closure three times.

Outer Framesheet

To provide even compression we’ve added an outer framesheet to the bag. This allows our 13L bag to evenly and securely slim down to clean and narrow package when needed. The sheet is also removable to use as a cutting or charcuterie board.

No Floppy Bags Here!

The lower compression strap design comes from the back of the bag, loops through the rack, and hooks to the front. This allows it to double as the attachment and compression strap.

Replacement Straps

All compressions straps are removable and replaceable. Prefer to compress the pannier like a dry bag? A mouse chew through one? No worries, we’ve got you covered.

Silence is Precious

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

Included in the Box

Pair of Ponderosa Panniers

Old Man Mountain Divide Rack and Ponderosa Panniers mounted to a full suspension bicycle.

Silent and Secure!

We set out to make the panniers that we wanted to use. That meant they would be durable, quiet, lightweight, and 100% waterproof.

Our cammed velcro attachment straps fit tightly and quietly to the rack. Our lower attachment strap is anchored to the back of the pannier, loops trough the rack and then hooks to the front, securing and compressing the bag with one strap.

FAQs

Please read our FAQs page to find out more.

Will the Ponderosa Panniers fit my rack?

Most likely, yes! The Ponderosa Panniers are designed to work with racks built for standard pannier mounting, including Old Man Mountain racks. Velcro straps at the top secure the bags over the pannier rail, while the lower compression strap loops through the rack to keep everything close and stable.

Check that your rack has a compatible pannier rail and a suitable lower attachment point before ordering.

Are the Ponderosa Panniers waterproof?

Absolutely! Ponderosa Panniers use waterproof laminated fabric, welded seams, and a roll-top closure to protect your gear from rain and trail spray. Hypalon reinforcements at key attachment points improve abrasion resistance and help the bags hold their shape.

Close the roll top properly before riding to get the intended waterproof protection.

How much can I carry in the Ponderosa Panniers?

Each Ponderosa Pannier has a 13L capacity, giving you 26L across the pair. That's enough room for clothing, food, tools, and other essentials for everything from a weekend overnighter to a longer bikepacking trip.

Pack heavier items low and keep the load balanced between both sides of the bike. Always stay within the load limits of your rack and bike.

How do the Ponderosa Panniers stay secure on rough trails?

We designed them to stay close to the rack instead of flapping around when the trail gets rough. The top Velcro straps cam over the pannier rail, and the lower compression strap loops through the rack to keep the bottom of the bag pulled in.

That lower strap is key to preventing the bags from swinging outward or developing the dreaded "dumbo ears" on bumpy terrain. Take a moment to tension the straps properly before every ride.

Can I remove or replace the Ponderosa Pannier straps?

Yes! The attachment and compression straps are removable and replaceable, so you can service your bags instead of replacing the entire pannier if a strap wears out or gets damaged.

The panniers also feature dual frame sheets for more even compression. The front frame sheet can be removed when you want to reduce weight or create a slimmer profile.

Excellent set of panniers. No problems in rainy conditions and tough enough for off -road touring in Scotland. Also great customer support by OMM, v quick response in replacing a pannier strap that came loose . Not sure if this was my fault or a weak buckle but they replaced it regardless. Super impressed!

Simple, solidly executed panniers. The mounting system is solid and secure, and with the frame sheet no sway. Relatively light weight. Not just for off-road touring-works well for road touring as well. The ability to compress the, flat is a nice feature that makes for a compact package if empty.

Simple, solid, and durable. Holding up well after 3500 miles of abuse on mostly trail riding, as well as a few months in the city on a commuter bike. There's a battle scar or two but they're fully functional and waterproof. A good match with the OMM Juniper trunk.
