Little bit bigger at 2.5L but I’m very pleased with the Roadrunner Burrito Supreme. US made by nice folks for similar price to mass market brand name bags.
I got it for long gravel rides but have been using it for fast solo 4hr+ road rides on my Tarmac with aerofly bars and an out front mount. The opening faces forward so it’s still easy access and the straps are plenty long for the aero tops.
Plenty of room for food and I’ll even throw an extra bottle in there. Makes clothing choice much less of a concern in shoulder seasons too. Just stash extra gear in the bag.
