Compare the JACK WOLFSKIN GRAVEX 15 and GRAVEX 20 waterproof bike panniers. Find out which capacity suits your bikepacking style, daily commute, or grocery run.
Quick answer
For day trips and light commuting, choose the GRAVEX 15; for longer bikepacking or grocery runs, the GRAVEX 20 gives you the extra space without sacrificing waterproof protection.
What stays the same between the two sizes
Both the GRAVEX 15 and GRAVEX 20 share the same rugged CROSS RIP PROOF 420D Recycled fabric, a rolltop closure that keeps water out, and the KLICKFix attachment system for quick on/off. The reinforced back keeps the bag stable on the rack even on bumpy terrain. That means your choice comes down to capacity, not construction quality.
When smaller capacity is an advantage
A 15-liter bag is easier to maneuver in tight spaces, lighter when empty, and less likely to catch wind on fast descents. If you only carry a change of clothes, lunch, and a small repair kit, the GRAVEX 15 leaves no wasted volume. It also fits more easily on a rear rack if you already have a second bag on the other side.
When you need the larger 20-liter option
The GRAVEX 20 holds an extra layer, a larger water bottle, or a full load of groceries. For overnight bikepacking trips where you pack a sleeping bag or extra food, the extra 5 liters make a real difference. The rolltop lets you compress the bag when it is not full, so you do not carry dead air.
Tradeoffs at a glance
- Capacity vs. bulk: The GRAVEX 15 is more compact and lighter, ideal for minimal loads. The GRAVEX 20 offers more room but takes up more space on the rack.
- Versatility vs. simplicity: The GRAVEX 20 can be compressed when not full, giving you flexibility. The GRAVEX 15 is simpler if you always carry the same small load.
- Price difference: The GRAVEX 20 costs slightly more (USD 54 vs USD 48). The price gap is small, so choose based on volume needs rather than budget alone.
