Size Guide

Pinnacle is defined as the most successful point or the culmination. The Diamondback Pinnacle Pant is the culmination of years of research and development. The four-way stretch fabric in these pants was developed for elite alpine military units. Wind, freezing temperatures and driving snow are no problem, and you won't slow down climbing around scaffolds, rooflines or crawlspaces. Just for good measure we added Dyneema-reinforced panels on the knees, pockets and cuffs so these pants could become family heirlooms. The Pinnacle Pant is designed with a meticulous eye toward movement and utility. We know we have succeeded in creating the most ergonomically designed, durable utility work pant in the industry.

Pants tear at seems after few weeks. Even with light use! Very disappointed

Great pants

Overall love my diamondback pants. This is the second pair I purchased and the only problem I have had is the second pair my left pocket was stitched together at one spot in the center.

Great pants

Extremely comfortable, they are stretchy, they move with you and they are very durable. I highly recommend these pants for people that move lots, crouch and stretch. There is tons of room for tools and accessories in your pockets and the adjustable waistband is great. Haven’t found anything bad about these pants yet. I will be buying another pair in the future.

Preferred pants

Excellent pair of work pants. Durable, and great fit. They stay up all day and I rarely need to adjust them during work. Even if I wear them multiple days in a row, they don’t stretch out or lose their shape. They have become my favorite pants and I find myself looking for them first after laundry day. Would recommend and would buy again.

New DB Pinnacle Pant!!!!

I have been wearing another brand high performance work pants for a couple years now and I have been happy with them. When I found out Diamondback was making high performance work pants I was super stoked. They make great tool belts,pouches,vests and accessories. So I expected them to knock these out of the park. I was not disappointed. The new Pinnacle pants are awesome. Super comfortable, Stretchy. Adjustable belt built in without a buckle to rub your stomach. I hate wearing belts so this is huge for me. They have pockets everywhere to meet your EDC needs and whatever hand tools you may want to carry. I will be buying more of these pants in the future. Great job Diamondback team.

Thanks for leaving this kicka** review, Luke!!
