You could put it under your jersey and bibs and Quasimodo it.

I guess that anyone who didn't know what a bicycling related toe-strap was also didn't know how to use a search engine to see one?

On those days when the morning is chilly enough to require tights and a long sleeve jacket I often use a toe-strap to secure said tights and jacket under my saddle once the day has warmed enough to not need the tights and/or jacket anymore. DOing so leaves my jersey pockets free for snacks or water additives.

Cheers

Another (very cheap) storage option I've used: if you don't need a second water bottle for the ride, you can use that cage to hold a tennis-ball can (with a lid).

This happened after the jacket got loose from the toe strap and wound up in the cassette, causing a 40' skid.

You can see a bit of the ruined RD in the pic.

I'm more careful with that rig now.

sucks to see.
its exactly what i was thinking when i saw the 1 toe strap holding a cotton sweatshirt though. I would want another holding the clothing in both directions(length and width).

I got one of these Revelate top tube bags for my longer rides: https://www.revelatedesigns.com/inde...TangleFrameBag

I also own a Camelback type backpack w/water, but it really kills my shoulders so I've decided to stick with 2 bottles of water and then put my other gear(light jacket) etc in the Revelate bag.

:(

As referenced multiple times in this post, a large variety of light jackets quite easily fit in jersey pockets. As do small snacks.
Are you storing something else in your jersey pockets that would prevent this?
Because you also stated that you don’t want to add additional weight in the way of anything but a small bag.
If you don’t want to use the pockets on your jersey and you don’t want a suitable bag or to add weight, what realistic solution were you hoping for?

Like every other poster here, my jacket fits in a jersey pocket. But some of my jerseys definitely have smaller pockets than others, so I only wear those on shorter rides when I don't need to carry as much stuff.

If OP is stuck on seat packs, the Ortlieb ones are light for their size. The Saddle Bag Two has 4.1L capacity, for instance.

Light Jacket.. yes, fits jersey pocket easily

What is this thing called “newspaper”? 🤣 I’m pretty sure my Kindle or iPad would not work as well as this little known substance.

On a more serious note, this is a timely post as my winter riding will go up quite a bit and my rides are getting longer now that I can no longer run. Crap, more stuff to buy! 😃

Arkel Tail Rider. 8l expands to 11. Perfect for unsupported 200 mile solo rides - extra 1 liter platypus, another half dozen energy bars, thermal tights/jersey/gloves, spare light, regular tool/tube kit, spare folding tire, map,TP, sunscreen.

You don't want a light jacket when the first mountain is 35, cloudy, and windy or to be wearing that jacket up the next mountain that's 65, sunny, and calm.

I have it on a regular rack, although they sell a saddle rail mounted rack for it.

OTOH, there are lots of rides where jersey pockets are ample.

If the weather is cool enough that I might need a jacket, it's probably cool enough that I won't need a second water bottle for a typical 20-30 mile ride. So I'll use the seat tube water bottle cage to hold my thin windbreaker. I stuff it into a quart sized ziplock baggie and jam it in the cage. That's worked fine for the past few years.

Thursday was unusually cool here in Texas, in the 60s (after temps in the 100s last week), with a chance of rain. I intended to ride 20 miles or so and took one 24 oz bottle, and stuffed the jacket into the second cage. Turns out I felt better than expected after warming up and did 40 miles. I needed the jacket for the final 10 miles as it was sprinkling and cooling down. Still had water in the first bottle when I got home.

I've stuffed that jacket in my jersey pocket, but I'd rather not. So far the ziplock bag and water bottle cage trick has worked for most rides.

I could have saved some trouble and worn a Pearl Izumi wind jersey I got last winter. With a good compression baselayer it's more aero and flaps in the wind less than a jacket, breathes better and doesn't get too sweaty. I've been caught in chilly light rain with it before and it was comfortable enough.

There are lots of extra large seat bags that will fit on any bike (even racing bikes) if you need to be self-sufficient for a big day out. Some of them are quite affordable, though they may not be as feather-light as high end bikepacking bags. For instance: https://smile.amazon.com/Banjo-Broth...-no-redirect=1

If you really just want to carry a jacket (beyond your current seat bag's capacity), frankly, I would just get a jacket that packs nice and small. They are great to have anyway and you won't be weighed down by extra-large saddle bags, or handlebar bags, etc. Bonus points if the sleeves come off (convertible jackets) because the sleeves take up almost no space and their removal greatly increases the temperatures at which they can be worn (as the day warms up).

Happy riding!

Lots of good advice above, too, some of which surely echos my own post.

I use a draw string bag to hold sundry items. I have several and most of them were giveaways. Small items still go in the jersey pockets.

This is a great handlebar bag for longer rides if you need to carry a layer and extra food. Just be aware, a bag like this will make it more challenging to mount a front light or a GPS mount.

I can lend you something.

My light cycle jacket tucks into it's pocket and has small straps to wear it as a waist pack. Maybe not ideal but I never need to find a place to put it and the decision to take it just in case is easy to make. Is that not common? Both of my cycle jackets have that function.

My compromise is a combination of a larger road seat pack (say 1.5 - 2.5 liters) along with a handlebar bag (I use this one from Jaand). The handlebar bag works to hold extra supplies without interfering with lighting/electronics, and can be easily removed for rides where it's not needed.

Like most people here, I use lightweight cycling-specific wind and rain jackets that can be stuffed in a jersey pocket. I also ride when it's below freezing, and the handlebar bag is good for stuffing items that are not cycling-specific, like a winter softshell, extra baselayers, extra gloves, and chemical warmers.

This is more of a gravel than a road setup, but here's the idea:

Hydration pack with storage, then put all your stuff in there.

I bought a gossamer weight biking jacket that has sleeves that zip off. I can easily zip off the sleeves when it warms up, to just wear the vest and the sleeves fit in a back pocket. If it gets too warm to wear the vest, it fits in an expandable seat bag with my phone/small tools and the sleeves go in the jersey pocket. Snacks and money/chapstick/kleenex go in a top tube bag.
