What size reservoir comes with it?

A 3 L bladder is included — bigger than the 2.5 L Osprey bundles with the Manta 24 — and the pack costs $30 less while weighing 1.4 lbs less. On pure hydration-pack math, the Citro is hard to beat.

How does a 2 lb pack compare to the 3.4 lb Manta?

The Citro gets there with a lighter suspended panel and simpler construction rather than by cutting ventilation, and 210D honeycomb CryptoRip is still a legitimately tough fabric. What you give up versus the Manta is the included rain cover and some suspension plushness.

No — one size with no torso adjustment, which is common in hydration daypacks but worth knowing before you order. The women's-fit Juno 24 H2O is the same design on a different harness if the unisex fit doesn't sit right.

I mostly use bottles — is it still worth it?

Probably not; the bundled 3 L reservoir is a third of the value proposition, and Gregory's Zulu 24 LT at the same $180 spends that money on 400D fabric and the fancier VaporSpan back instead. Buy the Citro for the bladder, the Zulu for everything else.

Does it come with rain protection?

No cover is included and there's no waterproof laminate here, so pack electronics in a dry bag or add an aftermarket cover. The reservoir at least sits in its own sleeve, so a bladder mishap won't soak your gear.

Gregory Zulu 24 LT

The Zulu LT is the lightened version of Gregory's ventilated day pack, using the VaporSpan suspended panel that holds the pack off the back. At 2.3 lb for 24 L it trades some weight for airflow, which is the same bargain Osprey's Stratos makes at a similar price.
