u/SomeStuffLikeThat

I have been looking through the Reddit posts, searching on websites, even asked ChatGPT for help...and now I'm finally asking here if the bag I want even exists? What I'm looking for is:

• Backpack around 25-30 litres
• Can be expanded for extra space
• Stowaway backpack straps
• Attachable shoulder/duffle strap (may have to buy this separately)
• Clamshell or lay flat opening
• Main compartment having a U-zip mesh cover
• Trolley sleeve
• Does NOT need a laptop compartment (just adds to the weight and I don't want to bring a laptop with me)
• Doesn't need a ton of extra pockets or straps
• Water bottle pocket nice but not necessary
• Must be able to purchase in Canada

Right now I'm leaning towards:

• Patagonia Black Hole Mini MLC but it's not expandable.
• Topo Global Travel 30L bag but it's also not expandable and the hip straps don't stow away.
• Osprey Transporter Travel Pack 36 but again, it's not expandable.
• AmazonBasics Carry-On Travel Backpack but it's a little large and I worry about quality.

Maybe I'm just being too picky but I really want to one bag travel and have the right bag for all my needs.
