  • PURPOSE BUILT FOR RUCKING: The Rucker revolutionized the fitness category of rucking (carrying weight on your back). These bags are purpose built for rucking with an elevated pocket designed for Ruck Plates, reinforced construction, extra padded straps and multiple handles to make it a versatile training tool. The Rucker helps you to get stronger one rep and one mile at a time.
  • SUPER STRAPS: Thin straps cutting into your neck is the last thing you want while carrying weight. The Rucker straps are wide, reinforced, and extra padded to create the smoothest possible rucking experience. To build the straps, two premium high-density polyethylene foams are heat laminated together to form a permanent bond. The interior foam provides superior cushioning against your shoulder, and the exterior foam provides outstanding durability and impact resistance.
  • HIGH AND STABLE WEIGHT - Keeping the Ruck Plates high on your back, stable, and evenly distributed puts you in the best position to gain strength while rucking. The elevated Ruck Plate pockets keep the weights from bouncing around the bottom of your bag, and lets you scale up to 75LBs of Ruck Plates (we recommend starting 20LB).
  • BACK SUPPORT: Raised padding along the bottom of the Rucker provides ergonomic lumbar support that protects your spine and helps to brace your core. The back panel’s 210D Cordura fabric is smooth and moves with you instead of rubbing against your clothes. Closed-cell foam repels moisture to prevent sweat and rain from damaging your ruck. A built-in frame sheet adds structural integrity to your rucksack, and allows you to carry more weight comfortably.
  • VERSATILE 20L CAPACITY: Compact yet spacious enough to carry essential gear, making it ideal for both fitness and everyday use.
  • PATENTED: GORUCK obsesses over revolutionizing the fitness category of rucking and designing the world’s best, toughest gear for you. As we invent the best products, we protect our inventions with patents. We have one issued patent for the Rucker - US 12053080.



Product Description

GORUCK RUCKER 4.0

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 Rucker 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 SHIRTLESS

Say goodbye to friction burn. 210D HT (High Tenacity) CORDURA on the back panel and underside of the shoulder straps does NOT cause friction burn on your skin and it plays well with less durable fabrics like merino wool.

ERGONOMIC LUMBAR SUPPORT

An additional 10mm of EVA foam padding along the bottom section of the back panel supports the natural curve of your back. It’s raised up, protects you from friction from seams on pants, belts or Tough Leggings or anything back there. And if it’s exposed to your skin, that’s no problem either.

EXTRA PADDED STRAPS

Shoulder straps and top handle are extra padded to carry heavier loads more comfortably. Our dual density foam will not collapse under the pressure.

OPTIMIZED FOR HYDRATION

Clip your hydration bladder into the interior d-ring with a carabiner and feed the hose through the exit port under the top handle of the ruck.

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.

GET STARTED RUCKING

Rucking is the action of walking with weight on your back. Walking with a weighted rucksack (aka backpack) is a low impact exercise based on military training workouts.

SPECIAL FORCES MATERIALS

A simple design, bombproof construction, and the best materials money can buy are trademarks of our brand. The materials we choose thrive in any environment - YKK Zippers (with silent zipper pulls) perform despite Middle East sandstorms, and 1000 denier CORDURA is the preferred material for Special Forces rucks due to its strength to weight ratio and durability.

I usually don’t leave reviews, but I love this thing. I’m around 6”1, 200 pounds and it fits perfectly. Seems very sturdy and high quality. Lifetime guarantee too. If you’re serious about rucking, just go with this. Stick with it and it’s cheaper in the long run.

Up your step game with some weight on your back. I’ve had my GoRuck 25L for over a month and it’s a beast. I use it daily. Supercool veteran owned company, top notch craftsmanship, and excellent customer service. Highly recommended!

Quality and craftsmanship were immediately recognizable. My rucks have been completely improved since I switched from my old backpack. It's better than I expected and I was expecting it to be great. Immediately ordered the hydration bladder, hose clip and s-clip from their website. Would have bought the bag directly from them but I had the points so might as well get it free. I bought the 30# plate with it and it fits great. I used a 5# regular barbell plate to increase the weight and it fit perfectly in the other pocket with zero movement or issues. Looking forward to logging some serious miles with this baby!

Super impressed with the quality of the Rucker. Excellent pack for 20 to 30lbs! 20L is very comfortable for 5’10 person at 160lbs

I don't have a problem with this pack being made in Vietnam. I do have a problem with Goruck obfuscating that fact. They are really playing the veteran owned, USA angle hard. The truth is that only one of their packs, the GR-1 is US made, and it costs $100 more. One star deducted. The strap system on this pack is just terrible. Packs built at this price point generally have smooth adjustable straps at both the waist and the shoulders. Modern straps are designed to cinch in a reverse pull. This allows easy balancing of the load. Adjusting the weigh distribution on the 4.0 on the fly is virtually impossible. I bought the waist belt for heavy rucks, but It is mostly useless because you cannot properly load it. The sternum strap is equally problematic. Many people, including the company owner, do not even use it. Now I see why. The strap system on the 4.0 is typical of a $30 pack. I've been backpacking for over 50 years, so I know what I'm talking about. On the plus side, the pack IS very sturdy. The straps are very wide set, which puts the load on the deltoids, not the traps. The plate storage scheme is very good. The zippers are robust and smooth. The pack should hold up to a lot of daily abuse. Given the price though, I would mark it as a poor value overall. $150 is more in line. I'm going to keep it as a daily beater plate carrier. My rucking sessions are usually an hour or less. I would not carry this pack for hours or days under any circumstance.

This is as good/better than advertised. The materials are really top notch and my only regret is that I didn’t order one earlier.
