The AP Rack Top Bag is designed to fit seamlessly to our Racks with minimal fuss.
100% Waterproof
The AP Rack Top Bag is constructed of a high-frequency welded, fully-waterproof, high-performance laminate skin.
Remove in 5 seconds
We developed the AP Rack Top Bag so that the rack could remain attached to bike and the pack could be easily removed.
Solid connections
The AP Rack Top Bag attaches to any Tailfin Rack using CNC-machined 6061-T6 aluminium alloy fittings, which together with stainless steel pins create an incredibly strong and rattle-free connection.
Easy to access, even on your bike
The unique roll-top opening of the AP Rack Top Bag makes it super easy to pack and find your belongings whether it’s on or off the bike.
Light it up
Use the twin rear light mounts to be seen and stay safe, while reflective strips provide additional visibility.
Stash pocket
Keep your most-needed items on hand in a zipped outer pocket.
Carry more on top
The twin stacking straps offer the ability to quickly, and easily stack items on top of the pack.
Direct Access Pocket
One of the challenges with any roll top bag is the speed with which you can enter the main body of the bag. The Direct Access Pocket allows you to get in to the main body of the bag without opening the roll top.
Speed off the bike matters
In a long journey, it’s often the time you’re stopped that makes the difference.
Fit your rear light effortlessly
Our additional Light Mount options enable you to fit any rear light to the back of the AP Rack Top Bag for maximum visibility.

Media Reviews
5/5. Adding to the excellent Tailfin Alloy Rack, the AP Rack Top Bag provides secure, waterproof and quickly-removable luggage to your system. Overall the Trunk Bag is a class act that perfectly fits into the Tailfin ecosystem of products.
The good: firmly attached to the rack, no rattling or moving while cycling. Waterproof.
Could be better: needing to undo 4 straps to get into the bag, doesn’t sit well on surfaces other than the rack when you take it off, side pocket doesn’t fit an iPhone.
My bike is small so I’ll probably have to get the longer rack top piece for it to sit better, just haven’t wanted to spend the $$ yet as it’s not cheap to replace! Wish I’d known this before buying the rack so I would’ve gotten the long one but live and learn.

A Perfect Rig setup
Like many who buy a Tailfin product love it so much they get hooked into the family of Tailfin products. I started with Top Tub Pack large and have to say it's never left the bike. I bought the alloy racks as I want to put my Ortlieb bags on it and it works perfectly . AP20 Trunk Top Bag. So much space in it perfect for storing Al my camping gear and finally a couple of mini panniers for the forks which are perfectly sized and balance the rig perfectly. I'm just waiting a conversion kit for the new mounts for the forks then I can do away with my front rack completely. Thanks Tailfin your awesome....

AP20 trunk bag
A great product, securely attaches to rack. Bag is nicely made but can be a little tight under the saddle.
I’ve been looking for additional bag options such as frame packs and handlebar bags. It’s a shame Tailfin haven’t come up with any products yet because there does appear to be an opportunity for them to provide something of comparable quality to the trunk bag.
Hi John,
Thanks for taking the time to provide your great feedback! We do offer the Topstay in a 'Long' version which provides an additional 50mm of clearance for the AP20 Topbag and i've been in touch via email on how to make this change.
Avoid the dreaded ‘yard sale’ effect when emptying your things at the end of a day in the saddle.
These Packing Cubes have been designed to simplify the packing process and to maximise the capacity inside Tailfin’s Rear Packs (AeroPack or AP20 Rack Top Bag) by incorporating clever shaping, thoughtful details, and high-performance fabrics. With all three weighing less than 155g, we think that better organisation is worth the minor weight penalty.
