Women's Furnace Long Jane



In Stock & Ready to Ship

Whether you drew a late-season elk hunt or are down to the closing bell in the treestand, First Lite's Merino-X Furnace series is the perfect tool for punching tags late in the season. Built with 350g EXP Merino-X weight fabric, the women's Long Jane is constructed for the coldest temperatures. Featuring flatlock seams and an articulated fit, they are ideal for layering over our other lightweight, next-to-skin styles. Our Furnace Merino-X fabric incorporates a brushed fleeced backside to our high loft, interlock knits to provide super-charged insulation without added weight. Adding this to the silent, odor-free benefits of merino wool, the Furnace merino is the hands-down choice for female hunters on cold weather hunts.

Favorite base layer!

My absolute favorite base layer pant! Great quality but I’ve found their base layers are extremely small. I’m typically size 2/4 and have everything in size Sm from here with exception of base layer gear. Ordered Sm and sent back for Lg. Did the same for the quarter zip, kiln set and furnace.

Small and poor quality

Purchased my size, small, my catalyst pants are small and give a little wiggle room. These arrived and looked like they were sized for a child small. I took one look at them and new they were not going to fit. Paid to exchange them for a medium. Still pretty snug. They are made for women who have absolutely no shape to them. They ended ripping in the crotch area after the fist use. Unable to exchange for a new pair and refunded me the money. It is what it is I guess.

Perfect base layer!

I am 5’2 and 125lbs. I bought a small and they fit perfectly. I do have shorter legs, so if you have longer legs expect them to be above your ankles. Warmest leggings/base layer I’ve ever tried. I like to wear them on there own after a hunt or fish, and my outer layer is wet, but I wish they had more color options. Perfect for keeping you warm on those late winter hunts and ice fishing.

Great product but size was way off

I have purchased a lot of Firstlite for myself and my hunting buddies as gifts... awesome quality that does the job of keeping you concealed or protected from the various weather conditions... So this time I decided to buy my wife the Furnace long Jane's for a xmas gift. The quality of the product is awesome but the medium I bought for my wife was way too small and she is only a size 6. I have to return them for the next size but these seem to run small...

These were gifted to me and I normally wear a medium in every other clothing item. The leggings I received are an XL and fit like a small. Not sure if I’ll actually be able to wear them for outdoor activities due to the size not being comfortable.

Excellent base layer

Worn these on a 10 day hunt in Colorado. Temps ranges from 15 to 46 degrees and these were a perfect addition to my layering system. I slept in them at night and wore them when temps were colder and when glassing....kept me very comfortable. Also, was really surprised how well they handled not being washed for that long. They didn't even stink!! Definitely recommend!
