Our inspiring overview is coming soon. For now, here is what Oveja Negra has to say:

Like its namesake (trucker lingo for a speeding big rig) the Gearjammer helps haul all the necessary items for overnight bikepacking trips and randonneur adventures alike. Lightweight, waterproof materials and bomb-proof construction create a light yet durable pack with all the features needed to securely store gear from your seat post. The Gearjammer seat bag has stiffened side panels and a plastic frame sheet that keep the pack stable and positioned away from your legs. This bag will not wag; the Gearjammer is one of the most stable seat bags on the market.


Our in-depth features analysis are forthcoming. For now, here is how Oveja Negra puts it:

  • Roll-Top design allows for variable volume packing
  • Exterior compression straps (x2 sides, x1 top/bottom) for unparalleled compression and load stablization
  • HDPE frame sheet retains the shape of the pack and distributes the load
  • Bomb-Proof 2″ die-cut and welded hook & loop seat post attachment strap
  • Gear Loops on underside of pack offer increased carrying capacity
  • Superfabric Grip provides a durable and highly stable contact point along the seat post
  • Nexus cam-locking buckles secure the bag to your seat rails
  • High density foam stiffened side panel keeps the load tucked away from your legs
  • 1050 Ballistic Nylon seat rail attachment point and wear patch
  • X-Pac VX21/VX42 laminated waterproof main body fabrics
  • MIL-SPEC webbing/binding
  • MADE IN THE U.S.A. of domestic and imported materials

Do it all bag!

The Gearjammer is really well made. I was a little nervous about how stable it would be with heavier loads but I've put all sorts of stuff in here for day trips (extra jackets, shoes, snacks, beers) and hardly notice it on the bike. Since buying this bag, I've purchased other products from Oveja Negra. All their stuff seems to be really nice quality. Love this bag!

Well made saddle pack

Some saddle packs tend to waggle if you get up out of the saddle but not this one. Its tough, burley. The straps are smartly placed for a secure fit. The construction of the whole piece is top notch and will last a very long time. Thanks for making a great product.

Excellent product and quality!

Excellent quality very strong this will definitely last a long time. If you are thinking on getting one go for it. You won’t regret!!

Steady and Secure

Digging this Oveja Negra Gearjammer. Already took it on a couple overnighters. It's very steady and secure....packs down well....pretty burly material...doesn't swing around (as long as you tighten it correctly) even with doing a few drops on my mountain bike. The extra loops on the bottom for strapping on additional gear are a great bonus. Just buy it already.
