Can’t decide between a traditional fishing vest and sling pack? We couldn’t either. So we combined the two for a best-of-both-worlds solution. Our 8-liter Vest Front Sling features our vertical-pocket vest configuration on one side, with a larger storage pack (like our Stealth Atom Sling) on the other. Access to either is simple; just swing the side you want around to the front without having to take it off. External nylon utility keeper provides secure attachment point for zingers, while a selection of easy-access pockets keeps the stuff you need handy. Inside, there’s a range of organizing pockets; a 100% waterproof, welded security pouch; and enough room for lunch, jacket and extra fly boxes.
  • Vertical pocket vest front with sling back combines the best of both worlds. Pack size is 8L
  • Rear pod can swing around to front without removing garment for easy gear access
  • Nylon utility keeper provides secure point to attach zinger, nippers, etc.
  • Internal quick-access pockets for tippet spools; organizational pockets with hook-and-loop closures; internal, 100% waterproof welded security pouch
  • Zippered back pocket provides plenty of storage for lunch, jacket and fly boxes

Vest Front Sling is rated 4.0 out of 5 by 24.
Rated 2 out of 5 by from Front Sling Vest I bought this vest last year for my annual Colorado trip. It has good storage and even a mesh pocket for a water bottle. However, the weight of my tackle, net & water pulled the back down so much that the front of the vest was around my throat. I had to use carabiners clipped to my belt to secure the vest from pulling down in the back. Very uncomfortable.

Rated 2 out of 5 by from Not very comfortable The sling has some nice features adapted to fly fishing but it falls short for wearability. The sling style wears out your shoulder when you wear it over your right like intended. After a couple hours your arm is worn out from casting and supporting the sling. Also needs constant readjustment like stated in other reviews. I'm returning mine to get the classic lumbar style because I hate vests

Rated 5 out of 5 by from Great Combo Sling and Light pack I am chest pack guy. I like having everything right in front of me, yet I like having everything I need, but no more. The Vest Front Sling allows me to pack what I want with the flexibility of having it where I want it. The only drawback is that there are no attachment points inside the chest pockets. I use these to secure my fly boxes and water filter. Overall, a great pack for the price!

Rated 3 out of 5 by from Could be great, Should be great...not quite there To vest or sling, that is the question. This pack has the potential to be everything to everyone, but ended up being less than what I hoped for or found useful. Clearly designed to appeal to those of us who log a lot of river miles and still see vests as the default option but want to roll a little lighter and cut back on what we tote streamside. In theory this sling does that but in practice I found it just annoying enough to take out of regular rotation while I rethink how to best use it. Ups: Logged about 25-30 days with this pack over two seasons of on-again/off-again use. Construction and quality of materials is rock solid and what you expect from Patagonia. Pack section is spacious...swallowed my normal fly boxes, headlamp, bug dope, sunglasses, phone, keys, and when needed, shirt or light rain jacket with ease. Front strap vest section held a decent sized fly box and was well thought out in terms of tool placement and attachments points. Downs: No way around it, the way the vest strap is designed just doesn’t work for me. Unlike other slings where the primary strap actually crosses diagonally across your body, this pack relies on a different configuration of straps to keep things in place and even with the back pack portion only moderately filled, the vest area kept slipping up my shoulder or needed regular adjustment. Keep trying to tweak this but still haven’t got it right. Might be a sizing issue, I am 6’2”, broad shoulders, and it just doesn’t stay in place like I need it to. Sideways: This pack holds a lot of promise and I haven’t quite given up on it yet. Highly recommend trying it on in a shop first with some items you would regularly carry on the stream to get a feel for it. I have found that all slings take getting used to and each have their quirks. After solid use over two seasons, however, the quirks still get in the way of what is an otherwise smart concept and great idea.

Rated 5 out of 5 by from Amazing versatile vest! An outstanding vest for fishing. Pockets are well designed, intrinsic, and well organized with locations to make managing flies and tippit in the water easy without the bulk of a vest.

Rated 3 out of 5 by from Do some research first Great idea, but has some issues. When using it in the summer, I didn't notice it as much, yet would still have to periodically adjust after a handful of casts. Just a week ago fishing the Jan thaw in WI, wearing a Primloft jacket layer, the shoulder would not stay on. The pack around the waist would ride up, due to the lack of friction, causing the shoulder to slip off. After 2 hrs of this I called it a day. From a storage standpoint the pack does great. The external water bottle holder is nice, as are the straps for either a 2nd rod or rain gear. Able to hold the need I need and some I don't in a very organized manner. Easily swings around for quick access when changing flies, grabbing a drink, or doctoring your line. Look at the pack, but also think about how you fish and do the research on other options ( This may work for some people. I personally, with the slicker layers, experienced the frustration of constant adjusting instead of fishing.

Rated 4 out of 5 by from Almost perfect. Almost. I've been using this for a few months now, and I've been putting it through its paces. I've been fishing with this on day trips through short punchy sessions after work. Having used it for quite some time, I can safely say that the sling vest is almost perfect. Everything about the design is pretty much spot on in terms of functionality save for one glaring problem: weight distribution. The issue arises when wearing a net and a water bottle. Minus the weight of a full bottle and net, the sling vest works very well - nearly perfectly. The issue with the weight distribution, unfortunately, causes even the most snugly cinched sling vest to have close to 3-4" of vertical play. This causes the front portion to ride almost over the right shoulder - a pretty annoying issue if you are wading and casting frequently. The constant readjustment is terribly annoying. Even taking down to the water causes the pack to shift enough to require adjustment every 5 minutes or so. If the overall weight isn't terribly disparate, the pack doesn't shift appreciably - however the times that this is the case is fairly minimal. Even for short sessions I try to keep a water bottle on hand to avoid heat stroke or dehydration. Even the water bottle (24oz) is enough to cause the problem, albeit less severely. Other than the aforementioned issue, the sling vest is basically a perfect functional piece of equipment for any fisherman. All of the pockets and pouches are in the exact place you would want them, and tool tethers are also in the place you instinctively reach when storing them. It is a shame the weight distribution problem is so pronounced - particularly when you consider the sling vest is basically perfect otherwise. If nothing else, it will only highlight and accentuate the problem! I still seriously recommend the sling vest - I've thought of adding a couple of weight vest slugs to try to counterbalance the sling vest to improve the distribution to make it better, since the sling vest is so well thought out otherwise.

Rated 2 out of 5 by from Good effort but poor performance in the field I've had my Vest Front Sling for just over a year now and I've used it (fly fishing) well over 30 times. I purchased it for fly fishing only. On paper, it's a great idea and you gave it a good effort but the actual use of this sling in the field is far from ideal. The foam fly patch totally fails to hold larger flies such as a sunken stones or a hoppers....the flies fall off (foam is inferior to sheepskin fly patches). The sling isn't great for accessing key items: having to swing it around is a hassle and having some items on the front and some on the back is impractical. Finally - most of us are right handed so having this sling setup to ride on the right shoulder is horrible for long days on the river. The sling (including the Atom sling) needs to be setup to ride on the left shoulder for the right handed fly fishing people which is about 80% of the market. I'll be going back to my Orvis vest for full day action on the river and back to my old Atom sling for the shorter trips.
