Aer’s product page for Travel Pack 3 now says that pack is discontinued and points here. We follow the live plate.

Travel Pack 4 35L is a lay-flat organizer: suspended 16 in laptop pocket, dual bottle pockets, luggage pass-through, hidden tracker pocket, lockable zippers. Those are Aer’s own bullets.

Shortlist reason: complete public spec block and a still-sold flagship. Tradeoff the numbers already show: 3.90 lb is not a ultralight number; X-Pac/Ultra pages list slightly lower weights at higher prices.
