The complete guide
Fabric weight and why it matters more than the price tag (LHI)
For a 3-5 day loadout, the LHI 35L Tactical Backpack is the size to reach for — 1.26 kilograms unloaded, in 900 oxford nylon. It carries a dedicated sleeve for up to a 16.5 inches laptop, MOLLE webbing for attaching gear as you need it, not fixed pockets you're stuck with, 4 compartments in total. The source listing shows 4.4 out of 5 from 45 buyers — a large enough sample to mean something, unlike a five-review shop-front rating. Folded flat it measures 29D x 25W x 42H centimetres, and it's priced at £99.98.
