Great mid and late season hunting bibs!

I purchased the sanctuary bibs size large and they fit and perform amazing. I wore them from 40 degrees with one light baselayer in Michigan to 6 degrees bow hunting in Missouri. 100 percent worth the money!!

Excellent Bibs

These bibs are warm and quiet. Used them in northern MN for whitetail. Temps were varying from 10-25 degree and wind was 10 mph. These bibs kept me toasty and out in the stand longer. The exterior leg pockets with elastic are great for shoving anything into them and not making noise with a zipper or fumbling a bunch. The fit worked great for me, however I bought these a size up assuming I'll get a bit bigger in the midsection. I typically wear 34x32 pants and if I ordered a large, it may have been a bit tight. Getting an XL was great for the fit. Very happy with the purchase and can't wait to get the sanctuary jacket for next year.

Very nice

Fit for me at least is true to form. I have now worn this bib and the matching coat in temps as low as in the teens. I think the outfit is very light weight, I'm surprised they keep one as warm as they do. That being said I think maybe a quality quilted woolen bib and coat would be warmer. Heavier, but warmer. I can't say they have ever heated me out. One issue would be pockets. I think the bibs could stand a utility pocket and the matching coat definitely could.

Close, but not perfect

I love my Sanctuary bib/coat set, they are absolutely the warmest set of extreme cold clothes I have ever owned. My only complaints are how heavy they are, the zippers are loud, and they are not the toughest material. They are incredibly warm and I know that usually means heavy, but I also think some competitors have similar products that are a pound or so lighter (don't quote me). And when you're hiking back a mile or so on public land to your stand, an extra few pounds makes a difference. I think there is some improvement to be made in the outer material with it's ability to take on briars, and I'm starting to see some wear on the crotch and inside of the thighs on the bibs, and the cuffs and armpits on the jacket, more than I would like during my 2nd season with them. I do walk a lot when I hunt out of state, but I would like to not replace my clothes every other year since First Lite would be considered an "investment" hunting clothing line. I think the zippers may be the biggest downfall, they are incredibly loud when you're sitting in the stand on a quiet, still day. I have to constantly remind myself to leave all pocket zippers open since my natural instinct is to close them. I've used all first light everything for 2 years now, and I am satisfied but I'm trying to be honest so that hopefully they will take into consideration these things and improve on the next gen set.
