Calling all outdoor FTWN (femme/trans/women/nonbinary) enthusiasts! Chain Reaction is hosting an inaugural FTWN Adventure Clothing Swap cohosted by Fearless Women of Dirt Cedar Rapids! Let’s be sustainable and give items a new life.

We’ll be swapping adventure clothing. Think things that to be active in - workout clothes, cycling or running clothes and shoes, outer wear, those hiking pants that don’t quite fit right, etc.

• This is for ‘adventure clothing.’ Yes to work out tops, no to stilettos.

• 1:1 swap - no money will be exchanged! Example: If you bring 5 items, you’re welcome to take home up to 5 items. We’ll be handing out ‘tickets’ that you exchange for items.

• Please bring items in good condition that have lots of life left that someone would be stoked to take home.

• Items not claimed will be donated locally. General items will go to Waypoint Women’s Shelter, bike items to Chain Reaction.

• This is NOT a bike swap or paid swap. CRBH will host a second annual bike swap in late March (!).

Bring some snacks to share as you like.

This evening is FREE and open to FTWN members of the community.

Any questions, please reach out to us at CRBH.Volunteer@gmail.com

Sorry fellas, this event is limited to femme/trans/women/nb volunteers and participants.
