Miles of muddy bridleway, a day of spring showers, torrential downpour that seems never to end… we do rain rather well here in the UK. Luckily, so does Fiana.

Fiana provides 12 litres of waterproof rackless storage for your bikepacking adventures, ideal for stashing clothing and compressible items.

Waterproof 450d TPU nylon and welded seams keep your valuables dry in all but the worst conditions. Roll-top closure keeps the water out whilst giving convenient access to your stuff.

Fiana attaches securely to your bike without requiring tools. Seat stay straps are angled to pull the pack into the optimal position below the saddle; the endoskeleton its underside improves stability, and contact points reinforced with Hypalon panels protect against abrasions, improve grip, and prevent sway.

An external mesh pocket is designed to hold a GPS tracker, bungee cord is ideal for storing extra kit, and an additional Hypalon tab on the rear is ideal for attaching a safety light.

When carrying electrical and other stuff that needs to stay dry, we recommend using a dry bag within your Fiana for added protection.

Another great product from Alpkit

I already had the Analoko, but needed a bit more storage for longer days on the bike. This range is really well made from a very hardwearing and waterproof fabric. It is really secure and there is hardly any sway regardless of how the bag is packed. The only small issue I've had is trying to release all of the air when rolling the bag shut. This was easily fixed by taping a small piece of flexible pipe inside the bag to release the air. Unless it gets submerged in water the contents will still remain dry. Maybe a small resealable air release valve could be added to the MK2?

Alpkit fixed the strap issue - 'cos they're awesome

See below for my first review. (Spoiler alert: bag is great, straps were too short on seat post end)
Alpkit followed up and sent me some extension straps to rectify. All now perfect.

Great pack for traditional touring bike, would be nice to see some road bike compatability added

Great pack, sits snug and the fabric is really smart.

My only greiveance is that the buckles that attach to the seat rails are too big and bulky to go through any of my road saddles (Selle Italia SLR, Astute). So I can't use the pack for commuting by road bike, which is partly why I bought. Perhaps size of buckles could be listed on the spec?

Would be nice to have straps long enough for slightly bigger/ aero shape seat posts too on future versions.

Bought on sale for £56. Amazing value, would highly reccomend this product, just make sure you have plenty of saddle rail clearance.

My Airlok tapered dry bag goes really nicely inside for added waterproofness and organisation too!

The Koala is better...

The perfect bag would be the Koala in this material.. I have other Rando products and the weatherproofness is perfect for British weather... However the strapping design on this bag needs to change for it to be of any value if you want to use more than half of it's 12l capacity.. The more you pack, the more it'll move as you ride.. In addition, the placement of the clips make it very hard to attach and trickers to keep in place.. For the price, I'd recommend you get a Koala and stick a dry bag inside.

not for the skinny

This is mostly great however on a 27.2mm seatpost the velcro isn't quite long enough. It could do with being 50% longer for skinny seatposts.

Nice bag shame about seat rail straps

I have just spent a couple of hours fitting my bags received in the rando bundle. All nice made bags but disappointed with Fiano specifically the seat rail straps. The buckle fitting to the strap is two large and the strap to short to go through any of my road bike saddles. They are therefore of little use. I can only fit they by putting the straps around the seat post with the main straps. This bit is not well designed

Straps too short

First ride (South Downs way) I came to fit the bag and found the seat post straps too short to connect securely to their Velcro patches. Post was only 27.2, so wide posts would be even more problematic.

Problem meant bag would not stay put.
Really disappointing, the other features seem awesome (materials, robustness etc) just didn't fit.
Have taken it to a cobbler the cut and stitch extensions for the straps, but is going to cost me)

Straps are too short

The seat post straps are way too short. When used on a 27.5 seatpost the straps don’t reach the end of the Velcro pad. Hopefully this isn’t an issue on rougher trails, and when the Velcro wears a bit.

The seat rail straps are also too short and make it very hard when trying to do the buckles up as they only just make it over the rail. This also seems to pull on the straps where they’re sewn onto to top of the bag. Hopefully the stitching lasts.

I purchased this bag as it was advertised as being waterproof and would save buying extra dry bags. I haven’t used it in the rain but it seems airtight when done up, as air doesn’t escape. I’m a bit concerned that for the new pre-order, it’s now recommended that you use dry bags for things you don’t want to get wet!

When used on a duallie, the bag rubbed on the back tire on a couple of fast causeway/creek crossings. Hopefully this was just the suspension travelling further than I thought, rather than the bag moving.

If the next iteration has the issues with the straps fixed, it will be worthy of a few extra stars.
