Gearjammer Seatpack
Oveja Negra Gearjammer Seatpack Review
Tested and reviewed for bikepacking use
The Gearjammer uses Oveja Negra's signature VX21 sailcloth in a harness-and-drybag system. The internal dry bag is fully waterproof with welded seams, and the outer harness cradle keeps it locked in place. At 340g with 15L of capacity, it's one of the best weight-to-volume ratios in the seat bag category.
Who Is the Oveja Negra Gearjammer Seatpack Best For?
Riders who want maximum capacity at minimum weight from a cottage builder. If that describes your riding style, the Gearjammer Seatpack should be at the top of your shortlist. It sits in the Seat Bags category alongside 9other products we've reviewed.
How It Compares
At 340g and $155, the Gearjammer Seatpack is 4g heavier than the lightest option in this category (the Apidura Backcountry Saddle Pack at 336g). The most budget-friendly option is the Topeak BackLoader 10L at $70.
The price-to-weight ratio comes in at $46 per 100g — a premium price point, but you're paying for quality, materials, and design that justify the investment for serious bikepackers.
What We Like
- +Excellent weight-to-volume ratio

Watch Out For

The Bottom Line
The Oveja Negra Gearjammer Seatpack earns a 4.4/5 rating. It's a solid performer that does most things well. Excellent weight-to-volume ratio is the standout feature, though harness-and-bag system takes time to dial in fit is worth considering before you buy.
