Not For Tea Pots

I've worn these snowshoeing in the 30's and thought I was going to pass out from how warm they are. I've worn them ice fishing when the temp was just about zero and was perfectly comfortable. I plan on packing these to my MN treestand and I know they will keep me nice and warm deer hunting. I bought a large that barely gets around my midsection but has way too much length in the legs. I'm short and a bit stocky; my bmi is 25.6, but I'm surprised at how these fit.

Great...until the wind blows

This series would be great if FL would incorporate Windstopper or something equivalent into their outer layers. Works well in a box blind but in a tree stand it fails when there's a steady wind. This seems like a no brainer. Fit is pretty tight around the abdomen so if you have any gut at all size up.

The Sanctuary Bibs are hands down the best set of bibs I have ever used for hunting. From the intricate pattern, to the efficiently designed pockets, to the vented leg system, to the incredible warmth... This was the best purchase I have ever made for hunting gear. I will be a FL customer for life!

Best Piece of Clothing I Have

I have had these bibs for just over a month and I can honestly say this is truly a quality garment and glad I went this route when I replaced my late season kit. I hunt around 40-45 days each fall from Oct 1 to Dec 31st in Ontario Canada and usually switch from to my cold weather set around 5-6 degrees Celsius (41 F) and anything below, which is about 2/3rd of the archery season.

Fit: I'm 5'11"and 195-200lb and wear a 42 regular suit jacket, mostly L fitting T-shirts, and 34x32 jeans and I bought a Large sanctuary bib and they fit perfectly. I really like the the waist adjustment so you can bring them in or out depending on layering underneath and to keep them fitted. I would say I'm just under halfway on the suspenders so I would say they would work for anyone within 3-4" of my height either way. I have to be more careful buying pants and need to stay away from anything labelled "skinny' jeans as my thighs and seat are on the larger side. The bibs are great in this regard as I don't feel like I'm wearing compression shorts like I do with some other hunting brands (UA) but they still have a good close cut.

Construction: Right out of the box the feel of the material is awesome. It has a soft synthetic feel to it but not like rubbery or plastic like some Goretex items have. They will shed water but I haven't worn them in an all out downpour either so can't comment on that. The zipper layout on the bibs is awesome as well. You might think its overkill to go from one side to the other but it allows for flexibility in having airflow for the walk in. I walk up to a km to some stands and usually have the zipper open about 12" or more around the knee but it doesn't feel like they are flapping around or falling off in anyway. Pocket layout is well thought out and like the outer pocket on top of the zippered pocket design.

The weather/temps starts to have zero effect on if you are heading to the truck or if you are waiting out a couple more hours in the stand.

Super warm

Warm, quiet and did I say warm already? Man, these bibs are outstanding. A little tight in the torso, but plenty of room in the legs for more layers. Now I can stay out longer than I thought was possible on those bitter cold days. Only complaint is that the suspenders don’t seem like they will stand the test of time. Overall, I’m glad I made the investment.
