Give the either the Osprey Momentum or the Osprey Escapist a good look. Both are cycling specific packs, and both have built-in rain covers. The Momentum Series have multiple padded compartments, that would fit both the laptop and the Ipad. The Escapist is more of a bikepacking style pack, and would require laptop sleeves. but has positively awesome back ventilation for long rides. Ton of features on both packs, and a variety of colors and sizes.
