ENJOY CYCLING ENJOY ROCKBROS！ NEW ARRIVALS Review: Great build quality. Great functionality and very practicle for sport bike riding. - Very impressed with this bag for the price, better than my Alpinestars leg bag which was double the cost. Has a retractable key chain hook in the main pocket which is awesome, is expandable which it nice in the event emergency you need to carry more stuff and don’t have room but the bag sticks out quite far if you have it extended. Waterproof is very nice for riding in the rain and peace of mind. Lots of storage and separate compartments for insurance/registration and stuff. Would recommend, nice build quality and lots of adjustability with straps to fit. Quick release waist strap is very nice too. Also used it skiing and held up perfect Review: Top tier for Daily and Motorcycles - Ahh where to begin. I get so many complements on this. It’s very comfortable and not too big. Rests very well on my side and is durable. The bag can also extend which is nice when needed for extra room. The clips are also amazing and sturdy. I use it when I ride my motorcycle and has become my daily go to. There is also an extension clip which is great for keys and recoils well. Honestly recently the side of the zipper breaking but I just need to sow it back on. Highly recommend! ## Features - Multi-functional magnetic motorcycle tank bag converts to thigh bag, waist pack, shoulder bag, or crossbody bag with 5 adjustable straps - Waterproof hard shell design made of durable Polyurethane material protects contents from rain and scratches - Large main compartment expands from 8.5 x 5.31 x 6.7 in to 13.5 x 5.31 x 6.7 in to fit phones, wallets, tools, and more - Removable magnets allow secure attachment as motorcycle tank bag; protective layer prevents scratches - Fits men and women for activities like motorcycling, cycling, hiking, running, camping, traveling, and outdoor sports ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0B8VLQ8CJ | | Best Sellers Rank | #4,465 in Sporting Goods ( See Top 100 in Sporting Goods ) #13 in Hiking Waist Packs | | Brand Name | ROCKBROS | | Closure Type | Magnetic, Zipper | | Color | BLACK | | Customer Reviews | 4.5 out of 5 stars 541 Reviews | | Item Dimensions L x W x H | 17L x 13.5W x 21.1H centimeters | | Item Type Name | Luggage- Messenger Bag | | Item Weight | 450 g | | Manufacturer | ROCKBROS | | Material Type | Polyurethane, Toner+210D lining | | Number Of Pockets | 1 | | Product Care Instructions | Clean with damp cloth and mild soap, avoid harsh chemicals. | | Size | 21 * 17 8.5cm (expand to 13.5cm) | | Strap Length | 36 Inches | | Water Resistance Level | Waterproof | ## Images ![Drop Leg Bag 3 IN 1 Motorcycle Waist Pack Thigh Bag 10L Black - Image 1](https://m.media-amazon.com/images/I/81jSxl6UMpL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great build quality.
