Splash jacket does help a lot. I wear a farmer John wet suit under dry pants and dry top for winter boating in WV. Lochsa is melted snow, going to be cold even in june. And you can buy a set of neoprene fleece lined gloves from Bass pro shop. They are for fishing, have excellent grip for paddling. They are called glacier gloves. Less than 20 bucks. Have a great trip.
