Nothing like jeans, but still awesome
I recently discovered Kuhl pants, and so far every pair I've tried on have looked and felt awesome. Amazing, because I rarely get that excited about clothes.
The "Jean Pant" is nothing like a pair of denim jeans, so I don't understand the name. The fabric is a nylon mix that is very lightweight but still feels tough. Nice and breathable and doesn't absorb much water. Cut is generous, without looking baggy, and allows great range of motion without binding.
Overall, a great looking casual pant that would also work well for bouldering. Or pretty much anything else I can think of.
