Just got done with my new ones on a hunt this weekend and they leaked through first day. I agree screen door material.I'm on my 3rd set of timberlines in 4 years. They've all be replaced due to leaking. I spent around 3 hours yesterday tromping around in the rain and they're leaking again.....the right one much worse than the left. I feel like their customer service has been top notch, but their membrane material should probably be relegated for use in screen doors.
They fit me really well and I want to like the boot, but at this point I wouldn't trust them to go on a long hunt and potentially have wet feet for a week because it rained on the first day.
They are definitely great boots, just not waterproof. Keeping them treated helps, but thick underbrush has a way of removing that stuff pretty quick I have noticedI have used Obenaufs on them to keep the leather conditioned and that has worked really well. That my help with the waterproofness as well. I cannot say enough about my boots, I think they may be my most comfy footwear.
