I discovered Sling Packs while searching for the ideal bag to take on the river for salmon fishing back in 2021. I liked the idea that by letting go one strap you can sling the bag over your shoulder to access the large rear compartment without having to take off the pack. This I presumed would be very convenient especially while stood up in the middle of a river with nowhere to lay a bag down.

I looked at a lot before I found the Patagonia Vest Front Sling pack at Outdoor Pros which offered another step forward in the convenience factor. Different from all the rest I looked at, this sling pack has two immediately accessible decent size pockets on the front strap. They easily hold a fly case, my phone, clamp etc., and has hanging points for tippet, Gink, nippers and more.

The main compartment has two zippered pouches, additionally two adjustable straps for tying something long or bulky on the outside of the main compartment. I used this to hold one of my rolled up Loop jackets in preparation for changing ever conditions, either my bug jacket or rain jacket. This proved valuable on the Lomond in 2021 as it began to pour rain while we were a long way's downriver. Having my Loop rain jacket immediately available made for a comfortable rest of the day.

Finally the main compartment has a water bottle holder on the bottom of the bag, and a fully waterproof ziplock pouch in which to safely store dry items such as your paper salmon license.

• I absolutely recommend a sling pack. If you travel light most sling packs will hold everything you need for a day on the river. I've worn this bag comfortably every single day both trouting and salmon fishing since 2021. All my gear is with me regardless of whatever other clothes I'm wearing, I don't have to swap equipment or licenses between different jackets or sweaters. 

• Always wearing my sling pack ensures that I won't forget anything especially my salmon license.

• It would be acceptable if this pack had a larger rear compartment. I can make do with it as is but I could fit a better lunch with little more space. Unfortunately this is the only model from any manufacturer I can find with the vest front pockets on the main strap and that's a feature I will not sacrifice now, it's awesome!
