Does this have an internal hydration sleeve (per website) Or external (as per manual on website??)

I would like to express my dismay ,wish I had read Alex's review before purchasing this backpack, it is extremely comfortable , but like Alex find my self with a useless top bag which doesn't change into a day pack. I have done an awful lot of research before purchasing this item and on all the different sites whether being You tube or other it clearly demonstrate the advantage of the detachable day pack. A feature i was particularly looking forward to on my 4 months trek.
Could you please let me know the terminology of the top detachable day pack for an aether 85 so that I can order one before my departure in 30 days.
This is very misleading indeed and not helpful at all to show one thing and sell another for a different country. Whether it rains more in Europe than some part of the states, it doesn't make any difference at to regard the usage of the day pack.

After hearing nothing but good things about Osprey packs i decided to bite the bullet and invest in the Aether 85 to meet my needs of hiking climbing and caving, i always look at reviews and videos before purchasing and all the reviews indicated this pack was super versatile and met the needs i would be using it for. However ,unfortunetly the reviews that came up were the non European version of the rucksack indicating a consistent 4-5 stars due to the versatility and especially the detachable top lid that turns into a day pack . That was the reason i bought the Aether AG 85 in the end compared to other Rucksacks. On arrival i disappointingly realised that the top lid/ day pack has been changed to a .. raincover.. for European models. I thought this was a manufacturer fault at first, as my thoughts were why would they regress and remove the top lid/ day pack when it was one of the biggest selling points of the product! I spent an hour looking for an explanation and it was only after reading other unhappy European customer reviews that i realised the useful top lid/ day pack was in fact replaced with a rain cover. I don't have the time to send this product back now and replace with a new bag due to having to go away on expedition, so my hand has been forced to keep this rucksack and insultingly purchase the £40 "DAYLITE" rucksack that essentially turns the European model into the version of the rucksack it should be. As a first time Osprey buying i am disappointed and insulted that this has happened and i can't fathom the logic and evidence of your market research for this, rain covers are readily available; Osprey branded or not but a top lid/ day sack is not and it appears European customers including myself are forced to buy the £40 Osprey DAYLITE and have a useless top lid that came with the European Aether AG. Adding a constructive comment to this, i would suggest it is made absolutely clear that the raincover is INSTEAD of the Top lid/day sack, because this has absolutely mislead me into purchasing this product, one could think the raincover is an addition to the top lid/ daysack as the logic for removing it is questionable and i would be interested to see your market research around this when i'm sure there has been ALOT of people like myself mislead by your marketing.
On an end note the actual bag appears to be well made and meet my needs it's just the toplid/ day sack i'm upset about.
