Outdoor gear is the perfect onramp for sewing, and it's how I got started!

Function is more important than form outdoors, so compared to say your work clothes it's ok if stitching is messy or fabric doesn't match.

Repairs are an easier way to get started than creating something from scratch, and outdoor stuff breaks. I've fixed and patched lots of holes, replaced a few zippers. Most recently mended the strap on my hiking pole that a critter chewed through overnight.

Gear modification is another ease into sewing. Old gear can be modernised, features can be copied from friends' gear, and gear can be customised to your specific needs. I've added ice axe loops and hip pockets to a pack, made a frame bag the exact size of my mountain bike, added elastic to a drawstring bag that wasn't cinching properly.
