Newbie here, so not sure what I can and cannot do. Finally have time to try and post some pics. Got my Tri-Star used but with the Absolute Strap (which is one of the greatest things ever) in September. When I was looking to get the Tri-Star I wasn't really sure what other bag would fit in the middle, but going by the dimensions I decided to go with the Ristretto for ipad to carry a netbook (don't have an ipad). Needed this to One Bag it on my travels. This is the first trip with the Tri-Star, a 4 day trip to Vegas in October. The Ristretto worked just fine, pulled it out as my in flight bag, and its the ideal day bag.
Please note: TB water bottle was not available at the time.
Middle had enough room for other stuff like my slippers (the light colored bag)... I'm from Hawaii... it's required footwear (for me).
Next pic always wanted to see how a water bottle fit in the Ristretto for ipad, took a chance that it would and it did, no problem, bag actually has a LOT of room. But for someone else who has the same concerns hope this helps...
3rd pic, my in flight items stored in the Ristretto for ipad.
Lastly... the Tri-Star had more than enough room for all my stuff. Packing cubes made organizing everything so easy (remote not included).
Conclusion: Trial run with the Tri-Star, a huge success!
