Aer builds carry-on travel packs, and Travel Pack 4 35L is the current one. Aer’s own Travel Pack 3 product page states that pack is discontinued and points to Travel Pack 4 35L, so our gear list follows the live SKU. Specs on Aer gear picks come from aersf.com product detail blocks (volume, weight, ballistic nylon, YKK, Duraflex).
