Hydration Vest
Matched to runs of 2+ hours and no price limit.
Why this pick
At 2+ hours you need more capacity than a belt can reasonably hold, and since you're fine wearing one, a vest is the right call here and not overkill. Since price wasn't the priority, this is the best-reviewed option in the category, cost aside.
Salomon Unisex Advance Skin 12 | 12 Liter Hydration Trail Running Vest, Black, X-Large
SensiFIT construction hugs the ribs close enough that bounce essentially disappears once it's dialed in, and 12 liters of storage handles everything from a long trail run to a genuine ultra.
Other options in this category
NATHAN Running Hydration Vest for Women Men, VaporAir 4 8L Running Vest
Real front and rear storage and a soft-flask setup that doesn't require a bladder, for meaningfully less than flagship pricing without giving up the core things a vest is actually for.
TRIWONDER Running Vest for Women Water Pack Hydration Backpack 5L Race Vest Lightweight Adjustable for Marathon Trail Running Hiking (Black - with 1.5L Water Bladder)
Won't match the fit or storage of the pricier options, but pulls strong ratings from a large volume of actual owners for exactly what it's meant to do at a fraction of the price.
