17-liter vacuum compression packing bag in durable polyester. Foldable, rectangular, and sized for carry-on luggage.Checked-bag fees add up fast, and the usual fix is leaving clothes behind. This compression bag takes the other route: shrink the clothes instead of the wardrobe. Soft garments compress down to a fraction of their packed volume, turning one carry-on into the capacity of two.Twice the Wardrobe, Same SuitcaseSweaters, jackets, and bulky layers collapse flat once the air is drawn out, freeing space for extra outfits, shoes, or souvenirs on the return leg. Two weeks of clothing fits where one used to.Sealed Against Damp and OdorsThe airtight closure keeps compressed clothing isolated from the rest of the case, which also makes the bag a clean divider for laundry: the suitcase for fresh clothes, the bag for worn ones.Packs Flat Between TripsThe polyester shell folds down to almost nothing when empty, storing easily in a drawer or a suitcase pocket until the next departure. Off the road, it doubles as seasonal closet storage for coats and bedding. Capacity: 17 liters Material: durable polyester Shape: rectangular, carry-on friendly Folds flat for storage between trips Suits travel, hiking, and seasonal closet storage Available in Onyx Trek and Cloud Trail.
