Not Durable!!! Needs Ripstop Material

Extremely warm, lightweight, and packable. DO NOT WEAR AS AN EXTERIOR LAYER!!!! Rubbed my back on a mahogany branch and ripped it to shreds! Totally unacceptable for the cost of the jacket and something that is supposed to be used in the outdoors. If you only pack this in or wear something over the top it will do fine, but don't wear it where it can rub on anything! Dissappointed!

Way too delicate for actual field use!

I purchased this jacket for a Wyoming Elk hunt. First time I wore it, the zipper ripped the shell in the pocket. They covered that under warranty. Got the replacement, wore it once in a tree stand in PA. Walked out of the woods and the sleeve caught on a thorn. Most fabrics would break the thorn off and maybe leave a small pin hole. This ripped two 4-5” slices through the outer shell and down went flying. If you want a $360 camouflage jacket for fashion, go ahead and buy it, but if you plan on hunting with it, buy from another company. They won’t warranty this damage and now I’m stuck with an expensive piece of crap I can’t do anything with. I asked to exchange it for a cheaper, less fragile jacket, but they refuse to work with me. I even offered to eat the difference in cost! Frankly I will not be buying anything from this company again.

Warmest puffy on the market!

I’ve tried multiple puffy jackets from different brands. This Chamberlin puffy insulation jacket is by far the warmest one I’ve ever worn. This jacket along with a couple base layers kept me warm in 0* November Montana weather. If you’re looking for THE warmest most comfortable puffy jacket on the market, this it it! Instant warmth when putting this on!

Warm SOB

I have both the Brooks Down Sweater and the Chamberlain. Both are warm SOBs. The Brooks is a little more versatile, ie more packable, better for layering but the Chamberlain blows the Brooks away in terms of warmth. That warmth comes at a price of packability. Just think about how cold you get and what you are using it for. For my backcountry Idaho rifle elk hunt this year, Brooks was the way to go. For my upcoming Minnesota late season whitetail, bet your ass I’m wearing the Chamberlain.

BE FOREWARNED - pattern does not match other products!

The Chamberlin is a very warm jacket, well cut for shooting and somewhat packable.

However, the First Lite Fusion pattern of this jacket does not match other First Lite Fusion fabrics. The lightest parts of the camo pattern are a very light blue in color; almost a very light Robin's egg blue.

I did contact customer service to see if it was a defect in the fabric or a bad batch of fabric. I was told that the different color variations in the Fusion camo pattern was due to the type of fabric that was used to construct the jacket.

I have not experienced this problem with other First Lite Fusion products such as the 5 Panel Tech Cap, the Grizzly 2.0 Trigger Mitt, the Uncompahgre Puffy Insulated Jacket, nor any of my wool First Lite products.

To me, this unacceptable for a company that purports to be the best in their field. Every effort should be made to ensure that different fabrics match a standard pattern. This one isn't even close.

Considering that deer are red - green color blind and can distinguish the color blue from other colors, I'm not sure how effective this jacket will be at concealment.

I live in Canada. Ordering and returning First lite products is a hassle so I'm stuck with this one. But you don't have to be.
