It’s not every day that you can go back and make something great even better, especially a product recently released and still enjoying immense popularity. Aer surprised us with a surprise release of one their most beloved bags-in one the most sought-after materials for a bag: X-Pac. This bag is now available as an addition to your EDC.

If you’re unfamiliar with X-Pac, it’s a a highly durable and waterproof layered laminate material designed to withstand the harshest conditions built by Dimension-Polyant, a company that builds racing sailcloths by trade and figured they’d make an excellent product fabric as well. This new first featured VX-42 material was used in the collection that celebrated its 5th anniversary.

But Aer didn’t fix what isn’t broken, so you still get an everyday/tech backpack loaded with features. The main compartments include the front and rear for admin organization, and the rear which can hold a laptop up to 15 inches and other flat items such as tablets. There is also space for organizing pouches. The bag also features a grab handle at the top, an expandable side water bottle pouch, and a luggage pass-through for when you fly again.

Altogether it comes with 14.8L of storage in a structured design that lets the bag stay upright when placed on a surface, with all the accoutrements you’ve come to expect from Aer bags, including YKK zippers, Duraflex hardware, a sternum strap, and comfortable straps paired with a padded mesh back panel for comfort and airflow for breathability. The zipper pulls of the X-Pac model have reflective details for greater visibility. This matches well with the bag’s eye-catching interior.

The is an EDC crowd favorite, with this X-Pac edition dialing everything to 11 while still keeping the bag surprisingly affordable and attainable. You don’t have to wait for special drops. Get it now.
