Sean: I hiked the WRR in 2014, the last 10 days of August. Route: entry at Upper Green River Lakes and exit at Big Sandy River TH. About 82 miles on the Highline trail + Fremont tail + many miles off trail, travelling generally southerly and easterly.
The above replies by BPL members provide you with good answers and explanations.
Definitely ditch the bear can and crocs. If you HAVE to have camp shoes, then take a pair of Adidas Supercloud flip flops (4oz). Airing out your feet is a very good idea. Take your shoes off at lunch, too. Even 15 mins of fresh air is a good thing.
Gloves are a good idea, especially with the constant wind: polartec powerstretch fabric weighs less than 2oz.
Salomon Windstopper Running Tights are great. I hike and sleep in them. 6oz. REI has them. Much better than hiking pants (comfort, compression, lighter, zippered ankle – easy to get on/off). Try them on to make sure they are not too tight.
My group experienced two nights of snow. Night time temps dropped to 10 degrees plus the constant wind = very cold. But that’s what happens at elevation in the WRR. Just put on all your clothes and sleep like a hobo. If you sleep cold, then take a 20 degree sleeping bag or quilt rather than a 30 degree. The wind creates convective heat loss which can be miserable is you’re not prepared.
Good luck.
BTW: I am hiking in the WRR the first 10 days of September 2016, so we can compare trips afterwards. my email = todd@360water.com
