Product Size: XL

Location: Tree stand
Primary Use: Late season

Very warm for all day sits in mid to late season hunts. Only need one base-layer with these on. Full zipper all the way around from one leg to the other makes it easy to dump heat on the walk in. Only reason I gave it four stars is they are a little short on me but minimal and I want them to have the built in gater like the north branch bibs

Just Received, No Field Experience

Just received the pants last night and was happy when I upped the size. I typically wear a pair of BDU pants under my bibs and when trying these on with a pair of pants the fit on the legs was excellent and there was a bit of room in the stomach but I am 26 and have plenty of time to fill out that section. I wear a large in everything else from pants to shirts. Make the decision on what you think but giving you the best info I can to make an educated guess. My one surprise was that the material was a little softer than I expected. It will certainly be quiet but we will see how the durability is with them. Will update the review after the deer season here in MN.

Amazingly warm and silent bibs

I wrote a similar review for the Uncompaghre jacket--I hate to compare across companies, as I am a fan of First Lite, Sitka, Skre and others. But when I got these bibs, I put my fanatic bibs on Ebay. And I really really loved those bibs. But these are as warm as the fanatic, as quiet as the fanatic, but they are lighter and don't pick up the same burrs that the fanatic will. They are similar in that you really cannot move around in them--stand hunting only from my perspective. I carry them with me and put them on when I get in the stand and get settled. But once you get there, they are magic. Great pockets--much better than the fanatic, and the zip up legs are also an improvement on the fanatic. Not to mention the full zip rear, which I haven yet to use yet, but which will almost inevitably come in handy why I need to ditch a Mitch in the woods . So warm that with merino base layers I was unzipping the legs in the low teens to not overheat. I imagine you could pretty much survive anything in these bibs, particularly when combined with the Uncompaghre.

Primary Use: Tree Stand
Fit Comments: Medium fits me great. I'm on the lanky side and wear 31x34 pants and medium shirts. I was worried that the bibs might not be long enough but they fit great. I wear a wool base layer and hiking pants under the bibs and a couple of wool layers and a polartec fleece under the jacket and don't feel constricted at all.
Great Treestand System

Every year I tell myself I'm going to invest in some warmer treestand hunting clothes but by the time the end of the season rolls around I put it off until the next year. I'm so glad that I finally took the plunge and bought this jacket and bibs. I've always worn a bunch of layers to try to stay warm but with all of the bulk it gets difficult to move around and draw a bow. This system is warm and easy to move around in, the slimmer fitting shooters cut sleeves are great. This is strictly an ambush hunting system, I pack the bibs and jacket in and put them on before I climb up into a tree. The fabric is not what I was expecting but it is nice, it's kind of a spandex feeling fabric on the outside which makes it very quiet. I have have been warm in them so far although the coldest I've used it in so far is probably around 20. The hood on the jacket is nice in that it adjusts snug and is not too bulky. The thigh pockets on the bibs are really handy, there's a zipper pocket with an elastic closed pocket on top which is nice for sticking gloves in.

Primary Use: Tree Stand
Fit Comments: Fit is very small for an XL and being 6'2&quote; and 222 lbs. If I get XL in other clothes I am usually swimming in them. I would advise to measure and adjust sizes accordingly.
Run small but very warm.

I read the reviews and it appeared most individuals were stating these ran perfect or close to it. I ordered the XL and found that they are short in length in the leg pretty bad. I had a very difficult time zipping up the front zipper even after letting the adjustable straps out and wearing a long sleeve short underneath. I am going to need an XXL and see how those fit.
