Rear Combo Bag UL
Seam-sealed tapered dry bag with integrated harness which attaches under your seat. This one piece bag is the lightest weight option for carrying gear under your seat.
If you frequently need to attach/remove the bag from your bike, we recommend checking out the Rear Harness + Dry Bag UL.
Made in New Zealand
All ROBO-KIWI bikepacking bags are proudly designed and made in New Zealand from a range of quality technical fabrics.
Hybrid Dyneema® Composite Fabric
Hybrid Dyneema® Composite Fabric (formerly Cuben Fiber) is a patented, ultra-lightweight fabric made of flexible non-woven composite laminates which are reinforced with Dyneema® fibres.
DCF is costly and for good reason. It's 15x stronger than steel and provides the highest tear and tensile strength of any competing fabric on a weight-by-weight and thickness basis.
The hybrid variant of DCF is a 2-layer laminate material combining a thin DCF layer with a polyester plain-weave face fabric, which adds strength and makes the material look more like a traditional woven fabric.
It is our fabric of choice for products that demand high performance durability and the absolute best in ultra-lightweight, waterproof fabric.
Dropper-post compatibility
The harness should be able to attach to the seat-post without issue, provided care is taken when fitting the seat-post strap and there is sufficient clearance to the rear tyre (at full suspension compression where applicable). Please take into account the under-seat to tyre clearance when ordering.
Reflective Bungee Cords
External bungee cord, quick-release hooks and toggles keep your kit convenient, secure and safe. Ideal for stashing and accessing spare gear while riding.
Ultra Light Dry Bags
Roll-top end closures ensure a secure and tight load. While the bags are seam-sealed and waterproof for the purpose of bike packing (brief submersion, eg. river crossings, deep puddles, torrential rain, etc.), prolonged submersion could result in water wicking through the velcro closures. The dry bag is not recommended for kayaking, rafting or water-based sports.
Hypalon® reinforcement patches
Hypalon® reinforcement patches provide strap adjustment options, increased grip and protection for your bike frame.
Visibility
Highly reflective logos keep you visible from all directions at night.
Fabrics & Colours (UL)
Choose from 3 external fabric colours for a unique setup that matches your bike or contact us for a completely custom look.
What to put in it
This bag is ideal for spare clothing and other items which need to be kept dry. It can also be used to carry overnight food, cooker, etc.
How to pack it
It is best packed first, then attached to the bike. Loosen the straps, thread them through your seat rails, attach the large velcro strap around the seat post, then progressively tighten seat rail straps and all compression straps, making sure to tension the bag up and away from your rear wheel. Once everything is adjusted, clip all strap retainers to their straps so they don’t flap in the breeze or get caught on things they’re not meant to…

Robo-Kiwi Ultra Light is our bag solution that goes all-out to create the lightest possible version of our products, while still maintaining functionality and durability. Excess weight is cut wherever possible. We use a hybrid Dyneema composite outer fabric, smaller buckles, narrower straps and velcro, lower density foam inserts, etc, etc.
The ultra light solution isn’t right for everyone. If you want bike bags so durable that you’ll be able to pass them down to your grandchildren, there are plenty of bag manufactures to choose from. If you want bags that have been shown to go the distance while saving significant weight over a standard bike packing setup, Robo-Kiwi Ultra Light is for you!
For the standard model, check out the Rear Combo Bag.
If you'd like to go even lighter than our Ultra Light Model, please contact us to discuss your requirements. There are a few extra tricks we can employ on custom setups to save a few grams here and there and if you are willing to make a few key trade-offs we can make significant extra weight savings.
