Awesome Review by Tampaflatsguy

Tampaflatsguy 9/17/2015

I bought this to use as a wade pack on the flats, and it's been amazing. Great craftsmanship, flexible enough to use in salt or fresh water. No grips here, one of the best packs I've seen!

Best Seller Review by WyoCaster

WyoCaster 9/5/2015

I bought one at the beginning of the summer, and love it still. It carries exactly what I need it to with a great deal of comfort. It sits perfectly on my back with no strain at the end of the day. It has held up extremely well, and does not interfere with my casts at all.

When doing wade trips it feels like I can move my arms more freely to get rid of tangles, carries all the gear I could need for a client, and they want to know where to buy one.

My shop has a hard time keeping these on the shelves. My friend bought one while we were in Montana and he likes it as much as I do. This is a great product.

Inconvenient and awkward. Left hand? Review by Chris

Chris 8/17/2015

After researching this bag and reading many great reviews I purchased one from my local fly shop. At the shop it felt very comfortable and very convenient....on the water, not so much. Maybe I'm missing something, but I truly feel like this bag was designed for left handers. The pack rests on my right shoulder, my casting shoulder, and when you swing the pack around all of the tools are stored on the left hand side. I found myself fumbling around more then fishing. The floatant holder ishorrible, I lost a brand new bottle of gink and shake on my first day with the pack. I really wanted to love this pack, but I did not. The craftsmanship is great, it looks very nice, but it just did not perform for me. I will be returning/selling this pack and going back to my fishpond guide pack.

If you are interested in this pack please go to your local shop and load it up with gear and test it out.

Great design but only on the right Review by Paul

Paul 7/20/2015

I love almost everything about this pack. It's got a multitude of spots to store pretty much everything you need for a day's fishing, including your DSLR if you're so inclined. The only weakness it has - which is significant - is that it only slings over your right shoulder. I didn't know until after a few trips that my own comfort zone is the left shoulder. As a result, I can't pack as much as I want to, if I also want to avoid a nagging ache in my right shoulder. If you think about it, your rod arm and shoulder shouldn't be the pressure point for the weight of the bag AND the weight of casting & pulling in fish all day.

Great, but some downfall. Review by Matt

Matt 5/25/2015

I love the bag except for one thing. When I slide the bag around to access the main pack, I unzip from bottle side to top with my left hand. I noticed that if I unzip all the way to the top I cannot one hand zip the pack close. I have to anchor the pack with my rod hand to get the zipper around the corner in order to one hand zip. It's not a deal breaker, but it is annoying. The pack is new so maybe with time it will break in so to speak. If not I'll still use it. I like get my gear up out of the water and out of the way. This style pack just makes sense for me. I may end up getting the large as well for winter/cold weather fishing.

Great way to down size Review by The big Skinny

The big Skinny 4/30/2015

Overall the pack is what I wanted. I was a guide for several years and got accustom to carry a heavy vest, but was looking to down size. I was scared that it would not hold all my gear I would want to take, but I reminded myself that is the point. It easily holds 4 large CF waterproof boxes a couple of cliff bars, keys, phone, and terminal tackle, and water bottle Takes a little while to get adjust to sliding the pack around, but it works great for me. The only concern I have is with where the cushion and strap meet. I had to make a wrap so the tab would get caught on buttons.

good overall Review by blake

blake 4/20/2015

I was skeptical at first when I saw the 89$ price tag but I decided to go for it, I defenately made the right choice. The first time you get your hands on it you can immediately feel the quality and craftsmanship and thought that went into making this item. The only drawback being that if you want to have good retractors that fit snugly you will need to spend an extra 30$. Overall a good pack. Just wish it came with retractors.

Just right Review by Joel

Joel 12/18/2014

Call me "Goldilocks". I've tried different hip bags (fancy fanny packs), full backpacks, and bulky vests. This bag is just right. Perfect size for 3 of my fly boxes, a bead box, extra rolls of leader and tippet, a spare reel spool, a handful of thingamabobbers, my keys and wallet, gloves, a stocking cap, snacks, and a small thermos for my dawn patrol coffee.

This is the style of pack that I should have started out with. Wife has a sling bag and giggled when I ordered one for fishing, but I'm sold. Perfect size for a light day trip, or fishing when you don't need extra layers and other bulky stuff.

I love that I can just undo the sternum strap and swing it around for a solid workspace. Tools at the ready, and it's got plenty of options for retractors and spare forceps. Interior space is clean, spacious, and well set up. It never got in the way of stripping and swinging, and I love that it sits high and tight.
This is my new go-to, and I'd highly recommend it.

Got this for fishing small creeks. Just the right size for a day-rip.
Completely replaces the vest.
