ELEVATED RUCK PLATE POCKETS

The elevated plate pocket keeps the weight high and secure on your back, which is the preferred method for Rucking. This will help prevent any injuries or friction on your back.

Both 20L and 25L Ruckers feature 2 elevated plate pockets, one that holds 20LB or 30LB (Standard) Ruck Plates and one that holds a 45LB Plate, 20LB (Long), or 30LB (Long). This means your rucker can hold up to 75 lbs of weight.

The 15L Rucker has one plate pocket that fits a 10LB, 20LB, or 30 LB Ruck plate.

ZERO IRRITATION WHEN RUCKING

Say goodbye to friction burn. 210D HT (High Tenacity) CORDURA® on the back panel and underside of the shoulder straps is less abrasive and doesn't irritate skin or chew up delicate apparel.

ERGONOMIC LUMBAR SUPPORT

An extra 10mm of EVA foam padding at the bottom of the back panel supports your spine’s natural curve. It’s raised to reduce friction from seams, and even if it’s against bare skin, it won’t rub you the wrong way.

EXTRA PADDED STRAPS

The shoulder straps and top handle are extra padded so you can carry the weight more comfortably. Our dual-density foam will not collapse under the pressure.

OVERBUILT CONSTRUCTION

Overbuilt with military-grade materials like 1000D Cordura® and YKK zippers, reinforced at every stress point, and field-tested in the harshest conditions.

OPTIMIZED FOR HYDRATION

Love long, hot rucks on the beach? Us too. Clip your hydration bladder to the interior D-ring with a carabiner and run the hose through the exit port right under the top handle — stay fueled, stay moving.

HIP BELT COMPATIBLE

Complete with side MOLLE to integrate perfectly with the padded hip belt. The hip belt allows you to distribute heavy loads to your hips over long periods of time (think the GORUCK Challenge or Star Course), plus keeps the ruck stable during Ruck PT.

TESTED + PROVEN

​​The GORUCK Challenge was born in 2010 to serve as proving grounds for our gear before it went to war. 1,000 Events/year, 175,000+ participants and 200+ Special Forces Cadre later (with no end in sight), the Challenge is the only quality control program of its kind. No other gear is consistently put through more abuse, and The Rucker® thrives.

SCARS LIFETIME GUARANTEE

The only ruck plate carrier you will ever need. Buy GORUCK gear once, and you’re set for life. It’s built with military-grade materials so it can take a beating — and if it ever fails, we’ll fix it right here in the USA at our Jacksonville Beach Headquarters. No fine print, no BS. That’s the GORUCK Scars Lifetime Guarantee.

One ruck, built to last forever.
