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.

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.

Warm & Quiet !!!!

I really wanted to order just an XL, but they are out of stock. So I got the XXL and crossed my fingers I wouldn't be swimming in the coat. The sleeves fit perfect! The rest of the coat feels just a little loose and baggy, but I can deal with that. It is by far, hands down, the quietest fabric I have ever had for hunting gear!! I put the coat on to practice with my bow, in 32 degree weather and just a t-shirt on under the coat, and I was starting to sweat.

Stay Warm!

These bibs are amazing! I used them into the single digits tree stand sits during the late season in Minnesota and never got cold with only a base layer underneath. The zippers for venting come in handy when walking in and out to the stand. Quiet, comfortable and so far they seem very durable. Highly recommend these for low activity in temps below freezing. Looking forward to getting the matching jacket!

Fit Comments: Fits two sizes too small.
3 sizes too small?

I got the 3x so I could just get to the stand and slip into these really easily no matter how many layers I had on. Well they will barely fit long johns underneath them? I’m so confused by this. To get this fit I would normally purchase an XL possibly a XXL with suspenders so I can on puffy pants under for super cold days with little movement. This fits like a tight XL which is what I would purchase as a summer pant. In other words I would never put on long johns underneath. The side adjustment velcro straps had to be let all the way out and it’s still pretty tight. This is the first out of a ton of first light products that I have ran into a sizing issue. Super saddened by this, cause I sold my Sitka incinerator bibs in 3xl, that I could swim in to purchase theseI’m 5’11” at a skinny 220lbs. No belly just stocky. So confused by this.
