The 1% of a travel bag Steven Bartlett obsessed over.

You know the move: knee on the suitcase, both hands on the zipper, praying. Here's what actually fills your bag - air. Pull it out and 15+ days of clothes, jackets included, drop into a carry-on with room to spare. The 20L Pro bag gives you up to 70% more space in the bag you already own. The lid just… closes.

The difference between a $12 bag and this one is the trip it fails on - the split seam, the zipper that won't hold, the bag re-inflated by morning. For the Pro, Ekster reinforced the seams along a wider, thicker edge for exceptional air hold and rip-resistance, even after regular repeated use. Waterproof, anti-rip nylon. Red Dot design, B Corp, warranty behind every seam.

Old vacuum bags make you feed clothes through a slot. The Pro's wider, boxier shape and half-clamshell opening create a wide entry, so clothes slide in smoothly and spread out evenly - even bulky items. Packing, unpacking, and repacking mid-trip is genuinely easy. Reopen, add the jacket, recompress. Done.

This is the 1% philosophy made literal. A small transparent window on the front lets you see what's inside without unpacking - and without giving all your secrets away. A side handle turns the sealed brick into a grab-and-go travel bag of its own. Tiny changes, but you notice them on every single trip. That's the whole point.

Most vacuum bags strand you the moment you leave home - there's no vacuum cleaner in the hotel for the trip back. The limited-edition DOAC Air Pump fits in your hand, runs about 20 compressions per charge over USB-C, and sucks like a real vacuum anywhere: airport security, the hotel, a friend's spare room. (Forgot it? The bag still works with any vacuum cleaner.)

That $50 the airline wanted for your bag? Keep it. Owners report a 100% drop in check-in fees - the kit costs less than one round-trip checked bag, and you'll never check one again. Everyone else is crowded around the carousel; you're already outside, bag in hand, in the cab. No fee, no bag-drop line, no lost-luggage dread.

Love your cubes? Keep them - sort your clothes inside the bag if you like. But a zipper squeeze doesn't remove air, so the suitcase ends up neat and just as full. Stuff 3 pairs of pants, 8 shirts, 2 sweaters and sundries into the Pro, pump the air out, and it squeezes to a brick 3× tighter. Structurally, a cube can't do that.

This isn't a hopeful new gadget. Ekster's vacuum kits hold a 4.8-star average across 50,000+ reviews, ride in more than 2 million travelers' bags, and are made by a certified B Corp from recycled materials. For the Pro, Steven Bartlett folded dozens of his 1% improvements into the most advanced version yet - the kind of proof a $12 mystery bag will never have.
