Gates at the Austin City Limits Music Festival open at 11 a.m. Friday-Sunday this weekend and next. Speed up by your time getting in by packing only approved items in an approved bag.

The bag policy has been updated: Backpacks and bags with multiple pockets are not allowed, and bags must be 14-by-11-by-5-inches or smaller.

• DON'T DRIVE: Here's how to get to ACL Fest

Small is a key word: You can bring small, single-pocket drawstring bags; small, empty hydration packs; and small purses or fanny packs. According to organizers, some bag exceptions might be made for parents of babies or toddlers with diapers bags, or those with documented medical needs. Go to the Family Friendly Entrance, which is to the right of the Barton Springs East entrance, if you fall into those categories.

• MORE: All our ACL Fest coverage

All bags will be searched; there will be bag-free lines for quicker entry if you don't have one.

Also new this year: No full water bottles, even factory sealed, are allowed. You can bring in an empty bottle (no glass) and fill up at the fest's hydration stations.
