KÜHL Men's RYDR™ Pant

Are they actually tough enough for heavy-duty outdoor work?

Yes; they feature reinforced pockets, double-needle bar tacks at critical stress points, and scuff guards at the leg bottoms, all specifically included to withstand high-wear environments and heavy usage.

Do they shrink in the wash?

They are made from high-quality, pre-washed combed cotton twill that is designed to be machine washable and specifically resistant to shrinking, so they hold their shape over time.
