Sawtooth Hybrid Jacket

300g Merino-X with DWR Nylon

$210.00 USD

Color/PatternFirst Lite Cipher
Add to Wishlist

The Sawtooth Hybrid Jacket sets a new standard in versatility for western and treestand hunters alike. 20.5 micron, 300g Merino-X wool provides the extreme odor resistance and breathable warmth you've come to expect from First Lite Merino, while DWR coated nylon panels provide critical durability and water resistance where you need it most--the chest and shoulders. Body-mapped to preserve core body temperature, we've added 60g 37.5 synthetic insulation behind the durable nylon panels in the chest for added insulation and wind resistance. The merino back allows for greater airflow in the mid and lower back where packs and trees trunks typically cause heat and moisture to build. Worn as a light outer layer for brisk early season days or worn in conjunction with other outwear for added warmth on winter days, the Sawtooth Hybrid defines versatility in a cornerstone of the First Lite layering system.

Fit Comments: I bought as a jacket and planned on layering under, wouldn't wear this as a jacket so the extra room is wasted.
Location: Mid layer
Primary Use: Midwest treestand hunting
Should be advertised as a base or mid layer not jacket

This "jacket" is very thin. I would consider this as more of a mid layer, or second layer than a jacket. I had this on over top of a FL crew baselayer, and was cold in 60 degrees with winds at 6mph. I expected this to be more of a hoodie or jacket than it is. The forearms are to tight to layer anything under than something skin tight. I do not like how long the sleeves are or how tight they are. If I could return this product I would. I have yet to make it into late season to try as a mid layer, but definitely wont count on it as a jacket anymore. Over the past few months I have swapped out my early season and mid season for all First Lite gear. If I could snap my fingers and do over again, I believe I would have went with all UA gear instead. Nothing against First Lite, I just feel like the gear it better utilized while moving than midwest treestand hunting. I hope that over time, the investment that I made in FL will pay off, and I hope that it all lasts as long as all my friend's Sitka gear does. I do doubt that the warranty/customer service will be as good as Sitka with how they stand behind their gear after field use.

Fit Comments: I like how the back extends down low onto my buttocks
Location: Idaho- hunting late October and late November
Primary Use: Keeping me warm
Love the concept, but...

Great as a mid-layer when temps are low and would be great in September hunting archery elk as an outer-layer.
The stitching on the cuffs was faulty on mine creating more than one thumb-hole. Nothing that cannot be fixed here at home, but at $200+ I do not think a garment should need to be mended after one 8 day elk hunt.

Primary Use: Treestand

I come at this review strictly as a PA whitetail treestand hunter. This piece is the only FL piece I've bought so far Im not the biggest fan of. 1. I've found consistently that Merino wool makes a fabulous wicking base layer, but it's awful as a mid layer insulator. Compared to Merino fleece is much warmer as a insulator. 2. and this is personal preference I suppose, the forearms are tight. Doesn't ruin the piece but wish they were looser. 3. It doesn't make a great outer layer piece either. For you Western guys it would be awesome considering there's insulation in the front, and breathability in the back for when you have your pack back there. But for the treestand Hunter having the open back on a chilly day this piece is simply too lightly insulated for even some milder days with brisk winds.

If the front matched the back...

Length (overall & sleeves)
front & shoulder insulation

No insulation on the back significantly decreases the temperatures you can use this in if you're saddle hunting since your back is completely exposed. I understand not having the insulation there for wearing a pack, but if there was an option to have it that would by the ticket.
shoulder/upper sleeve fit is very tight. i have an XL and tried my buddie's XXL and it feels the same. I am not a very large dude, but do ahve broad shoulders and this is tight under the arms and throughout the shoulders.

It's a decent piece and is fairly comfortable. i can wear it with a layer or two down to about 45-ish so long as there's no wind. If there's wind, that exposed back really gets you and can make for some pretty chilly mornings.

Product Size: XL
Fit Comments: Jacket size runs a little small so may want to go up one size, especially if you are between sizes like me.
My go-to jacket

If I had to pick my favorite piece, the sawtooth jacket is right there at the top of my list. I’m primarily a NE tree stand hunter for white tail and this is my go-to piece when walking to my stand on those cold mornings. This Jacket layers well under outerwear and over base layers. Sleeves are form fitting, not tight, and I’ve worn it over my heavy wool sweater comfortably. I’ve never been a “hood” guy and actually avoided them until this jacket won me over and now have my fare share. For me this jacket is the perfect balance of breathability and warmth where you need it.
