Stuff sack

The 3F UL GEAR rain kilt is available for $13 USD delivered on Aliexpress.

Lightweight and waterproof 15D Sil-Nylon rain kilt

Good rain protection and breathability

Velcro wrap, comfortably fits waist sizes 60-100cm

68g + 3g (stuff sack)

This waterproof rain kilt protects the area from the waist down to the shins from rain and scratchy scrub.

It secures around the waist with a velcro attachment.

The benefit over rain pants is that it doesn't require removing your shoes to wear, and is more comfortable on warm days where rain pants would be too sweaty.

The open design also provides good ventilation, comfort and mobility.

Pros

Lightweight
Quick to unpack and use (compared with rain pants)
Loose around your legs - so you can stride freely
Multi-use item: e.g. use as a groundsheet, tablecloth, or to sit on

Cons

Rain pants probably more suitable for freezing rain/snow
One size only: very short people may need to wear it higher up their waist, or fold/modify it
Hem not weighted - in windy weather it could billow? (could rotate it so the wind is not blowing into the flap)
Velcro waistband is not as secure as a drawcord, can catch on some materials, and the hook side can be scratchy on the skin
Velcro only wraps one way and eventually loses its stick
Sil-Nylon can cling to skin when saturated
Still need gaiters for full leg protection
Semi-transparent. Not great as temporary clothing (e.g. while washing pants/shorts)

DIY / MYOG

If you can make your own, you will get a custom fit and the features you desire, but it still probably won't be cheaper.

There are also some ways of making a skirt from material you might already have. e.g.

Convert ripped seam Froggs Toggs pants into a rain kilt
Use a garbage bag with the bottom cut out (drawstring). You probably have one as a pack liner already
Use polycryo e.g Duck window insulation film (Amazon affiliate link)
