Best Bibs I own

The butt is very well insulated and getting in and out of bibs with boots on is no problem at all with the zipper design running all the way through the legs. Great design.

mediocre product, would not buy again

Honestly I think that this product is over-hyped by the reviews on first lite's website. I like the Sanctuary Insulated jacket (bought it last year), just not the bibs. I thought they would be warmer than they were, (I can only compare them to the Cabelas MT050, dry plus, Carhartt bibs, Berne bibs, and Nomad bibs) These bibs are not that warm for me. They need some type of wind barrier in them and possible more insulation for a person's rear (or a reflective liner in the rear).
I put on my layers under these bibs which work well for me with Carhartt artic bibs (carhartt bibs I have found are little too noisy for bow hunting on calm days, but warmer than these bibs). My bottom layers consists of EWCS polar weight bottoms, wader liners, dickies work pants and then these bibs. I tried out these bibs before I took them hunting cause I don't like to freeze in the tree stand. The temp outside was 22 degrees fahrenheit, the wind 5-15 mph crosswind, I sat for only an hour and froze. For the first 20 mins my rear got cold, then my legs, hands and feet, and then my core started getting cold.
I don't have this problem with the Carhartt Artic bibs, I was looking for something that was quieter though. Since I got them during the Gravy boat sale, I am unable to return them. The body was huge for me, the legs fit right for layering, but the leg length was not long enough, (I can adjust the bibs once I get in the tree stand so my legs are completely covered, but I can't climb in and out of a tree stand.
. I am 6' 1", 145 lbs, with a 33.5" inseam. I wish they made a medium Tall. The pocket layout sucks, and it would be nice if there were pockets for a person to put his/her hands that had a berber fleece liner on the inside.

Great Bibs

Bibs are extremely warm with minimal layering. Have work in -5 temps as well as all day snow/sleet conditions and never wetted out.

I had to size up one size for appropriate fit.

Primary Use: Treestand hunting

I have worn these on approximately 20 hunts. I have previously bought and own a lot of parkas and bibs from other companies, always searching for lighter, and warmer. These are similar in weight or lighter and as warm or warmer than some of my other quality bibs. I did still get cold one hunt with temps around 12-15 and a fairly high steady wind. I like these better for a few reasons and not as much for others.

What I like. Warmth is very good. Weight seems lighter than average. The zippers all the way up each leg are great. The two sets of pockets are functional and placed well. The fusion pattern is great where I hunt.

What needs improvement? In my opinion the zippers are very loud. And have small gauge teeth which makes for a long agonizingly loud pull. The material does not fare well with briars and gets pulls fairly easily. This one needs attention- It is near impossible to get something out of a pair of pants worn under these bibs. There should be a zipper that allows access to interior pants pockets.
