Thule’s Construct 28L sits between a minimal computer carrier and a large luggage backpack. A padded sleeve for a stated 15.6-inch laptop gives it a practical starting point for workdays that occasionally become overnight trips.
Plan the space around your computer
Put the laptop, charger and daily accessories on one side of your packing list, then add the clothing or lunch items that must share the bag. The 28L label describes total capacity, not a guaranteed amount left after the work kit is installed.
The advertised screen category is not a sleeve measurement. A protective shell or separate sleeve changes the dimensions that matter. For this model, establish the usable opening and compartment clearance before deciding that your particular 15.6-inch computer is covered.
Where a middle-size backpack earns its place
A traveler who commutes regularly and occasionally stays overnight may appreciate a bag that does not require changing formats for every trip. The Construct is worth comparing in that role because the listing explicitly combines daypack use and laptop accommodation.
The tradeoff is that a middle-size bag can be more than you need for a device-only day and less than you need for a clothing-heavy journey. Compare it with the smaller work bag you would use daily and the larger travel pack you would use occasionally. Choose it when that middle ground matches most of your real trips, rather than buying capacity simply because it is available.
