Lightweight Waterproof 28L & 34L Travel Backpack | The Island Hopper 2.0

COR Surf Island Hopper 2.0 Waterproof Travel Backpack

The travel backpack that actually thought things through.

The Island Hopper 2.0 is what happens when you take an already-great pack and fix everything that bugged you about it. Waterproof ripstop exterior. Luggage-style opening. Hidden security pockets. Redesigned shoulder straps. And at 2.0–2.5 lbs, it's nearly half the weight of comparable travel packs — which matters a lot when you're moving through airports, hopping boats, or grinding out a long travel day.

Both sizes open flat like a suitcase, giving you full access to the main compartment without digging. There's room for shoes, multiple days of clothes, and still enough organization pockets for sunglasses, chargers, snacks, and the stuff you're grabbing constantly. The new front-access water-resistant zip pocket puts your phone and cables within reach without opening the whole bag. Gear loops at the top handle a hat or neck pillow, and a free YKK S-Clip is included so you can clip accessories on without digging through the main compartment.

Two hidden back-panel pockets keep travel documents and valuables out of sight — one is tucked under the luggage handle wrap and completely invisible. Smart.

28L — The Carry-On Killer At 19" × 11" × 9.25" and just 2.0 lbs, the 28L fits under the seat on most airlines, making it the go-to for carry-on-only travelers. It skips the waist belt in favor of an adjustable chest clip to keep the profile slim. Water bottle holder fits up to a 24 oz slim bottle.

34L — The Overachiever At 19.15" × 11.25" × 9.75" and 2.5 lbs, the 34L adds a hide-away waist belt for days when you need the extra support — and tucks it out of sight when you don't. Water bottle holder fits up to a 34 oz bottle. More volume, same no-nonsense build.

Both sizes available in Black/Green Zipper and Black/Black Zipper.
