    • Max comfort, high quality, great design/features
Size: Large
The Exofit NEX is hands down worth every penny. Your safety is paramount when working at heights and your level of comfort with comparability of loading your tools on the harness go hand and hand. If you are uncomfortable it distracts you from your primary focus on performing your job... there's simply none of that here. The ease of being able to quickly put on the harness and exit it is a nice feature with the locking quick connect buckles. Quick and easy adjustment is a savior when working in different weather as well, cool spring morning with a hoodie tends to be a bit more bulky and a quick turn of a dial gives you the extra room you need to be snug yet not constricted in your own device. I am a Union Ironworker and highly recommend the NEX over the Exo Ironworkers make. This harness has more padding and more features to assist to make a change to our ever changing environments. Definitely worth every penny to invest in something that we put our lives on the line with. Not a single complaint here. Great work DBI/Sala on another outstanding safety product. ... show more

    • perfect for commercial construction!
Size: Small
The manufacturing date for the harness was only 18 DAYS prior to receiving it in the mail. That to me was amazing. As far as fit, comfort, and quality, its the best harness I've ever worn. I'm 5'8" and weigh 160 and a size small fit great, although I may need to get a larger belt to go around the waist when I have winter gear on underneath. I work in commercial construction as a union carpenter and I need to tie off with a harness on a daily basis. I like to wear my Occidental tool bags on my harness and these were perfect for that. Bags don't sag on the belt one bit. ... show more

    • This harness is costly and is considerably more comfortable than the other low end harness' however
Size: Medium
Wearing a harness is one of the most irritating things to me; It's uncomfortable and moves when you are tied off. This harness is costly and is considerably more comfortable than the other low end harness' however, It's still irritating to me and the leg straps bother without a doubt, like any harness. The positive thing about this harness is also a negative; the hip pad, because when it moves up to your stomach while tied off the leg straps take your crotch with it. All and all it's a higher quality then normal fall protection but all the same B.S. with it running up. ... show more

I am 5’9 34” waist and this belt fits me perfectly, leaving room for extra layers in the winter. This belt measures 36” from the buckle to the first hole and 46” to the last hole. I hope this review will help someone find the perfect size for them! I promise you won’t regret it.
