DRIFIRE CAT1 Ultra-Lightweight Long Sleeve Baselayer | Flame-Resistant, Rapid Moisture-Wicking, Odor Control | Arc Protection

Very comfortable and good fitting. Definitely buying more from them. Haven’t had to use the fire retardant abilities yet, so that’s nice

Compared to Carhartt and Ariat, this FR shirt is lighter weight and more desirable to wear in 100 degree weather. Very much recommend this shirt!

These shirts are not cheap in terms of cost or quality. I hesitated at first to spend $70+ for a T-shirt. However, as they are American made, I took a chance and bought one. Since then I’ve bought 3 more. At 6’2”, 170 lbs, size large is a near perfect fit. Sleeve length could be an inch longer but its still very acceptable. I might try an extra large next as I’m trying to put on a few lbs. I do like the fact that they are made in USA. I recommend this shirt.

A little large in size but great in every other area

*Just got it out of the bag* Feels good but for a 6'3" guy, it fits a bit small. The sleeves go back when I fully extend my arm (doesn't happen often with other L sizes) it's definitely light weight but just from feeling it, I think it's going to tear easily.Also, it does have the FR rating in case you saw that other review that said it didn't. Maybe Drifire should make these a bit longer, specially the sleeves.

Excellent FR base layer for under outer FR. My work requires two layers and this is the perfect weight for summer months.

The quality of this shirt is junk!!! The very first day I wore it the cuff started coming unsewn from the sleeve on both arms. I new new FR clothing for the job I was on so I had to sew the cuffs back on that night. The next day the armpits started coming unsewn and the seams on the sleeves started to come unseen. So that night I got the sewing machine out and basically resewed every seam on the shirt. I would have sent it back right away but I NEEDED some sort of FR shirt for work. I highly do not recommend this junk!

Love the color and felt good on skin, used for wrk
