what rain pants am I describing?

While I believe “soft shell” is a typo, how about this?

https://www.ebay.com/itm/NEW-Patagonia-PCU-Level-6-Gore-Tex-Pants-Mens-XL-L-long-waterproof-trouser-bibs-/132787691286?oid=132710716755

of course they are probably more than 1lb, but are rather durable.

On the Ebay thread, the Dead Bird Stinger is likely to be quite the durable pair of outerwear, and is close to a pound. Hear’s a link to an inexpensive, yet rather “GREEN” pair in a size Large: https://www.ebay.com/itm/Arcteryx-Stinger-Mens-Ski-Pant-Large/113268428066?hash=item1a5f530d22:g:~K0AAOSw8MJbqDZq

If for hunting, have you checked out KUIU?

Chugach rain pants, full zip, 15.5 oz.

n/m. Doug beat me to it.

Thanks

the Kuiu’s would fit the bill if fit works

I looked at the Level 6 pants, I believe they are two layer Pac Lite; being military pants they might be durable enough for my use- price is right on them

I couldn’t pass up a pair (Patagonia Level 6) for $70, will let you know what I think
