ZERO IRRITATION WHEN RUCKING

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

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

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.

Training Sternum Strap (Removable + Adjustable)

Training Sternum Strap (Removable + Adjustable)

Keeps the Rucker™ secure without constricting breath or movement and is adjustable by the MOLLE on the straps.

Bottom Drain Holes

Bottom Drain Holes

2 grommets on the bottom of the ruck to drain water for when you find yourself doing hydro burpees in the ocean, lake, or fountain.

Hip Belt Compatible

Hip Belt Compatible

Complete with side MOLLE to integrate perfectly with the Padded Hip Belt. A 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.

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.

Developing Rucker 4.0

The problem we’ve run into is happening on our own driveways. After you do your buy-in ruck, then push-ups, it’s time to take your ruck off and do flutter kicks. My friends lack discipline to control their gear (Chris, Matt — looking at you). You slam your Rucker on the concrete, and there’s a Ruck Plate in it. Of course you set it down, front panel first because that’s easier, and it’s concrete. So you have three zippers that will eventually get crushed, over time. Gravity + USA Cast Iron Ruck Plate + Concrete >> we can’t build better zippers to withstand this. Nobody can. Then you grab it again, and push it above your head and do your flutter kicks. With the Rucker 4.0, we’ve kept the main zip because it’s not under threat from the concrete, but we removed those internal zippers so there’s less to go wrong, or to fail. We put enormous pull tabs on the Velcro-closure interior pockets so you can work them even with gloves on, even when it’s cold out.

And we took a lesson from the Ruck Plate Carrier and beefed up the top padding of the interior Ruck Plate Pocket for when it’s time to do bear crawls or burpees and the ruck will naturally slide forward a bit on your back. More padding is a better solution.

We hope you enjoy the comfort this extra padding provides so you can find discomfort in other ways. And we hope the added resilience to your Rucker 4.0 by making it even more of a purpose-built tool keeps you in the fight for all the days, weeks, and months of every year for the rest of your life.
