Big Mouth Leather Duffle Bag

Product Overview

The Big Mouth Duffle is a smaller version of the Doctor's Leather Duffle Bag to be a simple overnight bag. It was engineered with no breakable parts, like magnets, zippers, snaps or buttons and all stress points are reinforced with rivets and hidden polyester straps. The main body is built with one solid piece of leather to reduce seams and one piece on each end. And we sew at only 5 stitches per inch so there is more leather between the needle holes and therefore fewer holes to start tearing. Some leather bags are sewn with thinner thread to save money and so sew with the holes closer together, but then they start tearing like perforated paper.

Our leather is only the full-grain stuff, and it's thick. The interior has two large pigskin pockets and three additional divided pigskin pockets, which is stronger than the cow skin. One of the coolest materials we use is our custom 316 Stainless Steel. It's a fun one to research up on. It can hold up to 750 lbs. If your life is depending on something, you're going to want it to depend on this metal. Our thick thread is a very strong industrial marine-grade and UV resistant polyester. It doesn't deteriorate when the sun hits it, more designers should use it.

The mid-18th century Gladstone Bag closure goes right along with our design philosophy of building it for life. This was at the time when zippers weren't a thing yet and they needed to keep your leather duffle bag closed for travel. It doesn't need to be buckled, but you can. I use it as my camera bag and it is loved. I put an old Maasai blanket I picked up in Kenya along the bottom for padding and then my camera lenses and gear on top of that.

    Love this bag

    A great addition to the new "big mouth" line of Saddleback bags. I also have the Doctors bag which I love. This one is a bit smaller and I love the single strap entry. A great addition for anyone's collection!

    Amazingly professional

    Recently received countless compliments on this bag. While I’m grateful that others appreciate it, I love its functionality, durability, and timelessness.

    As Expected, Best of Things

    I am a fanboy. I admit it. However, let's give credit, where credit it due. SBL makes the best stuff. I own a backpack, briefcase, and now this, all great.

    This particular bag will be used for range outings, already got my compliments, as with all other products, highly recommend.

    Perfect size for gym or work bag

    This bag is right in between the size of the Dr bag and Tool bag. It worked great for a gym bag when you don't need to load up alot of items. It worked great for work and fits my 14 inch laptop perfect with addictional accessories. The gladstone closure very convenient when you need to get in and out of the bag quickly compared to a buckle style. This is also very lightweight compared to the Dr bag. Highly recommend getting one for yourself. I own most of SBL design and this one is a nice size for someone looking for a lightweight yet has enough space for work or gym.
