FirstSpear Line One Belt - BioThane®

Borrowing its name from an old NSW term for first level of clothing or gear, the Line One Belt has amazing tactical performance that maintains the high level of comfort and mobility usually associated with leather. Urethane covered Nylon provides superior strength and weather-resistance - this belt won’t crack, peel, or become stiff in frigid temperatures.

Specially tempered, non-slip coating eliminates “break-in” time and allows for flex like leather, yet it is impervious to sweat and water and will not stretch or lose its original shape. An excellent platform for concealed carry or for just keeping your pants up with style!

Small: 30" - 34" (39.5" Tip to Tip)
Med: 34" - 38" (43.25" Tip to Tip)
Large: 38" - 42" (47.5" Tip to Tip)
X-Large" 42" - 46" (51.25" Tip to Tip)

    Nice Belt

    Posted by Justin D. on 19th Jun 2020

    This is a very nice belt that seems to be made of great quality. The only issue I have is I wear a size 32 pant and the small is a little small for my comfort. I might try a medium and see how that fits.

    Great for women too

    Posted by Unknown on 19th Dec 2019

    I struggled to find a low pro, sturdy gun belt in a petite woman's size, especially with a front buckle area that didn't protrude out a ton. This works perfectly, and after a year of using nearly every day, it still looks brand new.

    Buy This Belt

    Posted by JZ on 21st Oct 2019

    I waited 2 and a half years to write this, but I feel compelled to because this is truly the best belt that I've ever purchased. 2.5 years of daily use both as an on-duty platform and off-duty for concealed carry and casual wear. I've used and abused this thing to the point that most belts would be shredded by now, but this barely shows any signs of use. There is zero wear on the areas my gear sits, and the only way to tell that it isn't brand new is some minor bending near the buckle from cinching it tight. It's definitely well made, and you can probably slap the damn thing against the wall for an hour and you're more likely to damage the wall than the belt. Zero issues with flexibility or staying up, rigid enough to support holsters, comfortable. Seriously, if you're still reading, just buy it. You won't regret it.

    My favorite carry belt.

    Posted by T B on 7th Sep 2019

    I have been using the black version of this belt for 2 years now. It is an outstanding carry belt. I disagree with one of the other reviewers who said this can’t support a CCW. I have run a Glock 19, 2 G17 mags, 1 Motorola radio, handcuffs (LEO), a baton, a tourniquet, my badge, and a flashlight with this belt for extended periods of time. I have a 30 inch waist, so that is pretty much everything that I can get. I also ran this belt at times in Afghanistan, when I needed a low-profile setup, but needed to remain armed. It is durable, doesn’t deform, but has a reasonable amount of flex to it, and isn’t bulky.

    All around excellent belt

    Posted by Hut on 27th Jul 2018

    The First Spear Line One belt is just a great all around belt. They are incredibly durable, stiff enough to support a full size IWB or a compact/subcompact OWB rig, and good looking enough to wear with dress wear or jeans. I've owned the khaki belt for a couple of years now, and like it so much that I came back to buy the black and mahogany colors as well to round out my selection. **Be sure to visit the First Spear website to get the proper sizing guide. The image in the description is misleading and could likely end up with the belt purchased being on the small side for some.**

    Very well made

    Excellent belt I love the material and cerakote belt buckles is a huge plus. Sizing on this sight is different than what's advertised on First Spear. Check the sizing on First Spear first to make sure you get the right size.

    FirstSpear Belt

    Posted by Bill Black on 27th Feb 2017

    Good looking belts I ordered a black and brown. I should have known better when ordering a small. The sizing chart states a S fit a 32-34 I wear a 32 but I am unable to use the belts due to the length being too short. I should have ordered a M....

    First Spear Belt

    Posted by Stacy Little on 10th Jan 2017

    This is my first item from First Spear. I am pretty hard on belts, especially during the summer I can sweat through a leather belt pretty quick. I am looking forward to testing it out. For the last week or so it is holding up well, keeps its shape, sturdy, and looks good too.

    Tough gun belt

    Posted by PS on 4th Jul 2016

    I bought this belt to replace a leather one. I like the rubberized material used, belt is stiff and sturdy but mailable enough. The buckle is low profile and the coating is durable which is what I wanted. I use this to carry every day IWB and appendix carry a Glock 27 and spare magazines. I've also used it to carry an Glock 22 in a level 2 holster and it was very secure. It definitely feels like it will last a long time.
