How to Choose the Best Fly Fishing Sling Packs

Choosing the best fly fishing sling pack can be a challenge as there are lots to choose from.

One of the first things to think about is whether your chosen sling pack is waterproof or not. This can make a big difference to your fishing trips as you may not be able to wear it in the water if it can’t handle getting wet very well.

The brand of your sling pack is also something to consider. Your fishing gear needs to be made to a high standard, reliable, and work as it is supposed to – you can only feel confident all of this will happen if you buy from a reputable brand that has good levels of customer service and satisfaction.

You need to have a budget in mind and stick to it. Some fly fishing sling packs might have all the features you want but is too expensive at the time of buying. Others might be cheaper than you would expect but fall down when it comes to useful and worthwhile features. You should always try to choose the best pack available at your chosen price point to give yourself the best chance of owning a good quality sling pack.

Cost is something that, unfortunately, tends to be the deciding factor for most purchases. As mentioned above, you need to be able to stick to your budget. That does mean that you may not get exactly what you want but this article can help you find a suitable alternative that is still awesome but meets your budget needs better.

Before deciding on your sling pack, have a clear idea about what features you want it to have. Some sling packs on this list will likely have features you hadn’t even thought of which is an added bonus but you still need to make sure the features you definitely want are included in the design too.

Fly Fishing Sling Pack Buyers Guide: What to Look For

There are a wide variety of fly fishing sling packs available so finding the best one can seem like quite a challenge.

Here are some things to look for when shopping for fly fishing packs.

Comfort and design

When you are out fly fishing, you will need to move around freely and you will likely be on your feet for long periods of time during the day.

Fly fishing packs need to be comfortable to wear and designed in such a way that they actually help you enjoy your trip.

Design features such as a padded sling strap, mesh fabric, and alike all help keep you comfortable and are things to look out for when shopping for fishing sling packs.

Storage Space

Sling packs are ultimately used to carry your fishing gear with you on your adventures.

Making sure you choose one of the correct size to give you the amount of storage space you need will be an important part of your decision-making process.

From fly boxes and rods to lunch boxes and a water bottle holder – you will need to check that your shoulder bag has sufficient space for all of your fishing essentials.

Pockets and Compartments

In addition to storage space, great sling packs need multiple pockets and compartments to help keep your gear organized and easy to find.

Having multiple storage compartments will allow you to separate your kit into different sections of your pack. This will make sure that you can get your hands on the exact piece of kit you need exactly when you need it without having to search your entire pack for it.

Sling packs with things like a net sleeve, space for rod tubes, and a water bottle pocket are also useful features to consider to keep useful items close to hand at all times.

Attachments

As sling packs come in different shapes and sizes, you may want to have the option to attach accessories and extra tools to the outside of your pack if there isn’t enough room inside.

Some packs have attachments where your fly rod can be attached and carried, others have MOLLE attachment stations where extra kit can be attached.

A fly patch, integrated net sleeve, and cord loops are all features that can help you carry more kit without having to increase the size of your sling shoulder bag.

Fabric and Denier

Sling packs need to be long-lasting and reliable throughout your fishing trips.

Choosing the best sling pack for you will involve a good amount of thinking about the material your pack is made from.

Most sling packs are made from nylon and polyester with each one having different strengths and weaknesses. Some sling packs are made from canvas but these packs are not likely to last as long as nylon or polyester ones.

High-quality materials need to be used in the making of your pack to give you peace of mind that it will be able to withstand the rigors of outdoor life on the water.

Denier ratings define how thick the individual threads that are used to make your pack are.

To be confident that the sling packs you are considering are of a high quality, a denier rating of between 600 and 700 should be expected.

Strength and Durability

Your fly fishing pack will likely take a bit of a beating from time to time so it needs to be tough and durable enough to cope with this.

High-quality materials, top-level manufacturing, and brand reputation will give you a good idea of how durable your pack will be before you try it for yourself for the first time.

Many great sling packs are quite expensive so you want them to last and perform exactly as you expect them to.

Water Resistance

Waterproof packs seem like an obvious choice seeing how fishing is a water-based activity.

That being said, a fully waterproof sling pack isn’t always the best option. For example, if you know you will be carrying wet kit with you at some point on your trip, you need to be aware that it isn’t likely to dry out inside a waterproof pack.

This might not be a big deal for you but it could be an issue if you are on a multi-day adventure and don’t want wet gear in your bag for the majority of that time.

If you are one of the fly fishermen who enjoy fishing in the rain though, then a waterproof sling pack is a great choice as it will keep all your essential gear dry while you enjoy your time on the water.

Some of the packs on this list aren’t fully waterproof but have a waterproof pocket where you can secure gear that you don’t want to get wet. This is usually a zippered pocket that keeps any water out even during heavy rain.

Price

As previously mentioned, the price of your pack will probably be the biggest factor in which one you ultimately choose.

Some high-quality packs can be expensive so a mid-range pack might be better suited to your budget.

Something to bear in mind though is that a cheaper price doesn’t always equate to better value as some of the cheaper options out there may not last very long meaning you will have to replace it after a short period of time. If this happens, it might actually be better value to buy a more expensive pack in the first place knowing you won’t need to replace it any time soon.

Fly Fishing Sling Pack FAQs

Fly fishing vest vs sling pack – what is the best?

Simms Guide vest product

Both have their merits and we certainly use a vest some days and a sling pack on other days.

Fishing vests are good for when you need a wide range of fly boxes and other gear at your disposal as there is a bit more carrying capacity and more pockets to keep everything organised.
But you’d be surprised how the weight mounts up with a vest – all those little things add up.

So we tend to favour the sling pack for fishing – say – a mountain stream in summer where you only need a handful of flies. Wheareas for a session on a technical river with a range of hatches and fussy fish we really want the full range of fly boxes and other options so a vest is better.

Fly fishing backpack vs sling pack – what is the best?

Simms dry-creek-z-sling-pack riparian-camo

We prefer a sling pack if you can get away with it because it is much more convenient from the point of view of accessing it easily and taking stuff our and putting it back in. A backpack stores more gear, and is definitely better if you are taking a lot of food, water and things like camera gear and safety equipment and fly boxes, but for ease of use on shorter trips a sling pack is ideal.

What should you pack into the fishing sling pack?

orvis sling-pack fishewear product

That depends on the trip, but for a simple outing you should pack: fly boxes, sunscreen, your car keys (ideally in an internal pocket) and food/snacks. We prefer to carry tools such as forceps, tippet, nippers etc on a landyard for convenience.

What should you pack into a fishing backpack?

Simms freestone-backpack-shadow-green_f20

All of the above plus a Camelbak or other hydration bladder, your lunch, a personal locator beacon if you are going into remove territory and a camera if you want to take some nice shots. Of course you can use your phone camera, but do so at your peril when you are wading as it is easy to drop if it is not on a strap.
