Wedgie Bag Expander

About this find

Sleeping bags can feel snug across the shoulders, and that is exactly where the Wedgie Bag Expander from Big Agnes helps. It zips into your existing sleeping bag and adds 7 inches of shoulder girth. Instead of replacing a bag you already like, you simply give it more room across the upper body.

This expander is built to pair with the bag you own, rather than being a single size for everyone. It is available in a variety of lengths and zipper sizes, so you can choose the combination that lines up with your sleeping bag. That range of options is what makes a proper match possible.

Because the expander zips directly into your bag, the zipper is the detail to get right. Look at the zipper size on your sleeping bag, then note the length of the bag itself. Choose the expander version that corresponds to both, so the two pieces are made to work together.

If your bag suits you in every way except the tight shoulders, this is a practical way to fix that one issue. Check your bag's zipper size before you order, since that is the detail most easily overlooked. You keep the sleeping bag you know and add just one extra piece to your pack.
