I'm needing some advise. I'm leaving for the North Slope out of Happy Valley for a Caribou drop hunt in 4 weeks. I'm really limited on weight and am wondering if I can get away with using my Kenetreks with gators and a pair of Wiggy's slip over waders for stream crossings. I've never been on tundra and am not sure if I have to have hip waders just to walk around in. Any advise is welcome.
