5-Year Warranty

ORTLIEB Manufacturer's Warranty for End Customers – 5 Years

This voluntary manufacturer's warranty ("Warranty") grants additional rights and does not affect the statutory warranty rights against the seller. The exercise of statutory rights is free of charge and independent of this Warranty.

Warrantor is ORTLIEB Sportartikel GmbH, Rainstraße 6, 91560 Heilsbronn, Germany ("ORTLIEB"), email: customerservice@ortlieb.de.

1. Subject matter and scope of the Warranty

ORTLIEB warrants that the product is free from material and workmanship defects under normal use. The Warranty applies worldwide to ORTLIEB products purchased from authorized retailers or online dealers or directly from the ORTLIEB web shop. It is limited to the first purchaser and is not transferable.

2. Warranty period

The warranty period is 5 years from the date of first purchase from a retailer or online dealer or directly from ORTLIEB by the end customer. The end customer is the customer who first purchased the ORTLIEB product for their own use — not for resale — from a retailer or online dealer or directly from the ORTLIEB web shop. The invoice or delivery date of the first purchase is decisive. Proof is provided exclusively by the purchase receipt or invoice. A repair or replacement does not extend or renew the warranty period; the date of the first delivery remains decisive.

3. Scope of warranty performance

In the event of a warranty claim, ORTLIEB will, free of charge:

repair the product itself; or
replace the product with an equivalent product if repair is impossible or uneconomical.

No further claims arise from this Warranty. Statutory claims remain unaffected.

4. Exclusions

The Warranty does not cover in particular:

normal wear and age-related changes (e.g., wear of surfaces, zippers, buckles),
damage resulting from improper use, overloading, or failure to observe assembly/care instructions,
damage due to third-party interventions, modifications, or the use of non-approved spare parts/accessories,
damage due to improper transport, storage, cleaning, or care,
chafing marks, holes, and tears caused by the user's own fault.

These exclusions apply exclusively to this Warranty. Statutory rights for defects remain unaffected.

5. Making a warranty claim

The first point of contact in warranty cases is generally the retailer or online dealer with whom the purchase contract was concluded. A direct claim to ORTLIEB is possible at any time and is not dependent on prior involvement of the dealer. To make a claim, please provide:

a brief description of the defect and, if possible, meaningful photos,
the product designation (and any identification/serial information),
a copy of the proof of purchase (invoice/delivery note showing the date of first delivery),
your sender/contact details for queries and return shipment.

ORTLIEB will confirm receipt and inform you about the further process. Processing will take place within a reasonable period after receipt of the complete documents. Contact for warranty processing: customerservice@ortlieb.de

6. Transport and shipping costs

Within the European Union, ORTLIEB bears the reasonable outbound and return shipping costs of the warranty processing. Outside the EU, ORTLIEB will assume the costs upon prior written approval. Please contact us before dispatch and await the return instructions. Unapproved chargeable express or special services will not be reimbursed.

7. Applicable law

This Warranty is governed by the law of the Federal Republic of Germany. Mandatory consumer protection provisions of the state in which the consumer has their habitual residence remain unaffected.

Seat-Pack

£150

Get ready for your next bikepacking adventure! As a key item in your bikepacking setup, the ORTLIEB Seat-Pack comes with hook and loop straps to enable convenient and secure mounting to your seat stem. Projecting backwards from the seat stem, your Seat-Pack also serves as a rear fender. The spacious, waterproof Seat-Pack keeps its contents (e.g. an extra set of clothes) safe and dry. Depending on how long you plan to be away and your Seat-Pack model, you can conveniently adjust the volume of your pack from 8 to 16.5 liters or from 4.5 to 11 liters by adjusting the roll closures on the sides. An additional valve allows you to quickly and easily compress your soft gear for a more compact fit. Your Seat-Pack also serves as a replacement backpack when you’re out on a day trip, no matter whether you ride a hybrid bike, a mountain bike, a road bike or an electric mountain bike. The Seat-Pack is available in two sizes. The smaller of the two models needs only six centimeters on your seat stem. That’s why the more compact model is ideal for smaller frame sizes, full suspension bikes and adjustable seat stems.

Warnings and safety information

Risk of injury due to incorrectly attached products! Before riding, check that the product is securely fastened.
Risk of injury due to material breakage if overloaded! Do not exceed the maximum payload of 3 kg. If necessary, weigh your load to ensure that you do not exceed the maximum payload.
Risk of injury due to the seat tube clamp opening! Make sure that the bag does not touch the seat tube clamp and therefore cannot open the seat tube clamp while riding.

Care and usage instructions

Wipe clean with a damp cloth or clean with warm water and a mild soap solution. Remove heavier soiling carefully using a soft brush and gall soap.
Allow the bag to dry completely before storage.
To achieve protection class IP64 (6 = dust-tight, 4 = protected against water splashes from all directions), the closure must be rolled down 3–4 times and secured downward.
Keep free of coarse dirt.
Do not store the bag rolled up or folded, as this may cause the coating to crack.
If the product is fully submerged, water may enter through the closure.
Store protected from UV radiation to prevent the material from fading.
Reproofing is not necessary. The fabrics have a waterproof coating and therefore do not require any additional chemical treatment.

Our high standards for raw materials extend the product’s lifespan and conserve resources.

Does the Seat-Pack fit my saddle?

The Seat-Pack fits most standard saddles with a round seat post up to a diameter of 34.9 mm. It is attached to the parallel saddle rails and can also be used on carbon saddles.

Is the Seat-Pack waterproof?

The Seat-Pack is waterproof according to protection class IP64. This rating indicates:

The product is dust-tight and protected against splashing water from all directions. Even in very heavy rain and splashing water, the contents stay perfectly dry. The Seat-Pack is therefore ideal for longer outdoor adventures in stormy conditions.

More about waterproofness

What is the difference between the Seat-Pack and the Seat-Pack QR?

The Seat-Pack is mounted in the classic way using robust hook-and-loop straps on the seat post. It is lightweight, durable, and ideal if you want to leave your bikepacking setup permanently on the bike.
The Seat-Pack QR features a quick-release system that allows you to mount or remove the bag quickly and without tools. This is especially practical if you switch it frequently or use it on several bikes. Additionally, the QR model is particularly compatible with dropper posts.

Can I mount a Seat-Pack on my bike with a dropper post?

Yes, but the Seat-Pack QR is a better choice to maintain the movement of the seat post.

How long is my warranty?

The Seat-Pack is designed for longevity and often accompanies you for decades. To give you peace of mind regarding durability, we offer a five-year warranty on materials and workmanship. If the Seat-Pack does get damaged, almost every component from straps to buckles can be repaired. Even if a model is no longer produced, spare parts remain available for at least ten years.

Our warranty terms
How ORTLIEB products can be repaired

How robust is the Seat-Pack?

ORTLIEB products are extremely robust because we use high-quality materials and permanently weld all seams. This eliminates the need for stitching or bonding, and all connections are at least as strong as the material itself. If something does get damaged, holes can be safely rewelded by us or by our authorized service partners.

More about ORTLIEB materials

Can I mount the Seat-Pack on a carbon seat post?

Yes, the Seat-Pack can be mounted on carbon seat posts. We recommend applying protective film at the contact points to avoid abrasion and damage.

Is the Seat-Pack worth the price?

ORTLIEB products stand for durability and repairability. The Seat-Pack is manufactured in our factory in Heilsbronn, Germany. We source materials locally, regionally, or internationally depending on what meets our high standards. We invest time in development to ensure the functionality of every detail.

Thanks to long-lasting materials, the bag is a reliable companion. Its lifespan puts the purchase price into perspective, especially since we offer a five-year warranty on our products. A wide range of repair and upgrade options further improves the price-performance ratio.

Repair before replacement: Every product is designed to be easy to repair and can, in most cases, be serviced by our Customer Service team in Heilsbronn. This extends its lifespan and conserves resources.
