Eagle Creek Pack-It Isolate Compression Cube Set review

The Pack-It Isolate Compression Cube Set is the clearest case on this list for compression that is backed by numbers. Eagle Creek publishes both states for each cube: the Medium measures 14 x 10 x 3 inches and zips down to 1 inch deep, going from 7 L to 2 L, while the Small goes from 10 x 7 x 3 inches and 3 L to 1 inch and 1 L. The cubes weigh 2.9 oz and 1.9 oz, so the pair adds under 5 oz to a carry-on. The fabric is 100% ocean-recycled 70D nylon that Eagle Creek describes as water-resistant and made without the intentional use of PFAS. The set costs $50, and Eagle Creek also sells an M/M/M set and single cubes at $25 (S) and $30 (M) so you can grow the system. The trade-offs are the small piece count and the solid fabric: you cannot see inside without opening the zipper, so labeling or color coding helps.
