I'm going to be taking a very long trip on my r3 the last week of August into Labor Day weekend and had a question for any of you guys local or experienced in riding the Rockies. I'm going to be riding through Colorado on roads that go up to 10kft, at that time of year do you think id need a heated vest or will I be alright with standard ballistic removable liner textiles? I will be at altitude for a few days, camping etc. I've looked at climate charts but the deviations are huge so it's hard to say from them. I'm a lifetime 800fter, so any guidance will be appreciated. Thanks.
