While I was in Special Forces and Emily was in the CIA, we started GORUCK out of her house in war-torn West Africa. The goal was pretty simple: build a rucksack with life-or-death quality standards that would thrive in Baghdad and NYC. What makes our products unique? The GORUCK Challenge was born in 2010. 1,000 Events/year, 175,000+ participants and 200+ Special Forces Cadre later, the gear is battle tested. Why do we love what we do? Service is a way of life and that’s our northern star and we’re grateful to the community for the support. We would not exist without you. How did we get our start?

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. Compatible with our hip belt (sold separately). - 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. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0DDZPCXZD | | Age Range Description | Adult | | Apparel Closure Type | Zipper | | Apparel Fabric Stretch | No Stretch | | Apparel Fabric Weight Class | Medium Weight | | Backpack Design | Daypack Backpack | | Backpack Harness Type | Shoulder Harness | | Best Sellers Rank | #14,183 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #36 in Tactical Backpacks | | Brand Name | GORUCK | | Collection Name | Rucker | | Color | Black With Black Embroidery | | Customer Reviews | 4.7 out of 5 stars 229 Reviews | | Fit Type | Standard | | Fit to Size Sentiment | Positive | | Global Trade Identification Number | 00840360215153 | | Item Dimensions D x W x H | 5.5"D x 4.53"W x 18"H | | Item Shape | Rectangular | | Item Weight | 1.72 Kilograms | | Lining Description | Water-resistant lining | | Manufacturer | GORUCK | | Manufacturer Part Number | R420-0101EOB | | Material Type | Nylon | | Maximum Weight Recommendation | 75 Pounds | | Number Of Pockets | 3 | | Number of Compartments | 2 | | Number of Items | 1 | | Occasion Type | Exercise | | Other Special Features of the Product | Water Resistant | | Outer Material | Nylon | | Pattern | Solid | | Pocket Description | 11"W x 6.5"H | | Product Care Instructions | Machine Wash | | Product Style | Fitness Ruck Pack | | Recommended Uses For Product | Outdoor | | Shell Type | Soft Shell | | Size | 20L | | Sport Type | Rucking | | Storage Volume | 20 Liters | | Strap Type | Padded Strap | | Style Number | c9693391-cc55-4757-a411-f34795c097bc | | Theme | Military | | UPC | 840360215153 | | Unit Count | 1 Count | | Water Resistance Level | Water Resistant | ## Images ![Rucker 4.0 20L Rucking Backpack Black Rucksack - Image 1](https://m.media-amazon.com/images/I/51TF0JNzZYL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by A***Y on March 26, 2025* ### ⭐⭐⭐⭐⭐ Review *by C***3 on July 8, 2025* ### ⭐⭐⭐⭐⭐ Review *by K***E on February 12, 2026* ## Frequently Bought Together - GORUCK Rucker 4.0 20L Black - Purpose Built Rucking Backpack, Military Weight Training Rucksack w/Ruck Plate Pocket and Extra Padded Straps - Yes4All Cast Iron Ruck Weight, Weighted Plate for Rucking, Swings, Squat, Strength Training - Multiple Weights: 10LB to 45LB - GORUCK Padded Hip Belt - Adjustable Weight Lifting Belt for Enhanced Comfort & Stability, Ideal for Long Rucking & Heavy Lifting Work, Compatible w/Side MOLLE Webbing on GR1, GR2, & Rucker - Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/657216503-rucker-4-0-20l-rucking-backpack-black-rucksack](https://www.desertcart.jp/products/657216503-rucker-4-0-20l-rucking-backpack-black-rucksack) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-05-05*
