The JHFLYCO 20L Waterproof Sling Pack is built for anglers who don't back down from weather, water, or tough terrain. Whether you're hiking through rain or wading deep, this fully submersible pack keeps your gear bone dry and right where you need it.
Crafted from rugged 500D PVC with seam-welded construction and sealed tight with a TIZIP® waterproof zipper, it's built to handle whatever the day throws at you. The padded, adjustable shoulder strap is designed for all-day comfort and can be worn left or right, while a stabilizing waist strap keeps the pack secure during high movement or deep wades.
Inside, the 20L capacity offers generous storage for fly boxes, layers, tools, and more—without adding bulk. An internal mesh pocket keeps tippet, leaders, and small essentials visible and organized, while an integrated Velcro fly patch gives you a dedicated spot to dry and stage your flies between fish. A dedicated landing net sleeve fits the JHFLYCO 37" Landing Net perfectly, and the external D-rings, gear anchors, and water bottle holder ensure everything else has its place. Sturdy, reinforced attachment points stand up to hard use, so you can rig on tools, nets, and accessories with total confidence.

Perfect design for my purpose. I'm taking it to carry my belongings to work and fish in my property in Patagonia. Most of our days are in a boat and under heavy rain.
I'll send photos soon!!
Thanks
I bought this for wade fishing in Montana, where bear spray , side arm, and a packable wind breaker are edc. It carries all your gear for a day comfortably and keeps it dry, and in a pinch will serve as an emergency float to hang on to if you fall. Everything I hoped for and more.
Great size wading bag for my two boys who love to fly fish the Manistee and Au Sable rivers in Michigan. I love the material. These bags will see lots of action. I’m so glad that I found this company on a Google search! Fast shipping as well!! Thank you so much!
At first I thought this was a bit small, but I needed this for a saltwater fishing trip. Small enough to pack all the things needed for a day on the flats!
I purchased the JHFLYCO Waterproof Sling Pack for my son which is active-duty military and when on leave, he loves to fly fish! I received the sling pack and gift cards in time to wrap and place under the Christmas tree! He loves that it is waterproof and large enough to hold not only his fly boxes but other items he typically has to leave on the stream bank.
This is a great pack. Good size for including lunch and layers with your flyfishing gear. I wish the strap attachment had a different quick release, but that's just a nitpick.
I purchased the aluminum fly box and the waterproof sling pack. Both items were delivered quickly and the quality looks great. The sling pack is big and I've loaded it up with some gear and it is comfortable. It is one big compartment with an exterior pocket and that is fine. I'll probably get some bigger fly boxes to maximize the storage dimensions and implement a diy divider system of some sort which is fine, not worried about it. External hoops and straps allow for more gear and customization. very good price and the quality looks great.
My new JH Fly Co waterproof sling pack made it through its first test. A week on the Delaware River system with inclement weather confirmed the weatherproofing of this bag. It held up well and kept my gear dry! My only recommendation would be adding a removable divider for the interior of the bag. Can be frustrating digging through the large 20L pack in pouring rain, trying to find that extra fly box or leader wallet…. Overall, a great bag for keeping everything dry!
Simple and looks well built. I have not yet used it in rainy/wet conditions , but it looks like it will do well.Has enough places to add zingers on the outside. Some suggestions : the main compartment is very large, an internal sleeve divider can help to separate fly boxes from other fishing gear without adding bulk or weight.
Love this product !
Does exactly what i wanted. Plenty of room to store multiple boxes and gear. Its very comfortable to wear while fishing and easy to swing around to change flies. Price is perfect .
This sling pack has quickly become my go-to for all of my fly fishing adventures. The waterproof construction gives me peace of mind, especially when wading through streams. The size is just right � not too bulky, yet roomie enough to fit all my gear comfortably. The adjustable strap is a game-changer, allowing me to turn it easily to grab my fly box and change flies. The quality and attention to detail are evident in every aspect of the pack. It's a must-have for any angler who wants both functionality and durability.
I picked up the JHFLYCO Waterproof Sling Pack with the thought I'd just use it for trout and bass fishing here in Washington State. It has worked out great for that. Plenty of room, comfortable and of course its water proof! I've also brought it with me on my Mexico saltwater flats trips and its been awesome for that. I'm often wading into some pretty deep water and the pack keeps everything nice and dry. Of course, room for flys and extra rain jacket, water bottle, etc. Love this pack!
The JHFLYCO Waterproof Sling Pack has exceeded all my expectations. It's perfectly designed for my fishing needs. The waterproof material that is is made out of effectively protect my gear from any moisture and the layout of the pockets are super intuitive, ensuring quick access to my fly boxes or other gear. The overall comfort during extended wear is impressive. This pack has become a crucial part of my fishing gear for its functionality and attention to detail.
I've been using the JHFLYCO Waterproof Sling Pack for a while now, and it has become my favorite fishing pack. The waterproof material that the pack is made of truly works � my gear stays totally dry even in unexpected downpours or when I accidentally dropped it in the creek. The pack's organization is genius � I can fit everything I need without feeling weighed down. The padded strap is a game-changer for comfort, and the sleek design is a nice touch. This pack has added convenience and style to my fishing trips.
