Mountains Walking Brewery's Damsel Fly is a West Coast-style India Pale Ale brewed in Bozeman, Montana, sold as a 4-pack of 16 oz cans. The beer is hopped with Strata and Idaho 7 hops, delivering bright notes of orange and melon layered over crackery malts with a subtle undercurrent of grassy dankness. It finishes clean and refreshing, making it a standout example of a hoppy, sessionable IPA from the Northern Rockies.

Mountains Walking Brewery is a locally owned craft brewery and pub rooted in the terroir of Bozeman—its altitude, climate, and native wild yeasts all shaping the character of each beer. Damsel Fly is one of their flagship canned offerings and earned a Bronze Medal at the 2022 World Beer Cup in the International IPA category. The brewery donates a portion of Damsel Fly can sales to Warriors and Quiet Waters, a nonprofit supporting veterans through fly fishing therapy in Montana.

The beer has an ABV of 5.3%.
