Broken Zinger Review by Bob

Bob 5/31/2014

I purchased the vest and within four months the Zinger that is built into the vest broke off and was told to send it in and wait for it to be repaired. I ended up continuing to use it and put a temporary zinger on to hold me over until the season was finished which is very soon for trout. However, Bass season is starting up and so now I have to be without the vest until its repaired and since I am not permitted to repair it myself, I will most likely have to go out and purchase another vest to hold me over until the repair is made. So the final question is do I purchase another Simms that is really good except for the zinger that broke off or do I purchase another brand to hold me over until my Simms comes back.

Top Drawer Review by Piano Man

Piano Man 4/29/2014

In an economy where I've noticed a lot of company's product quality slipping, Simms products have not followed suit. From design through to the finished product I am actually proud to wear your name. The sizing is perfect. The placement of pockets and zingers are perfect. I anticipate wearing this vest forever. Or until my sons find it. Thank you Simms for keeping quality as your primary objective.

Simms Best Choice Review by Wolf

Wolf 4/14/2014

Have been looking to replace my vest for a few years now. Didn't have the heart to throw it out. Has faithfully served me for 20+ years.
Hoping for another winner. Much nicer than my previous vest.

longchuck 4/1/2014

the g3 guide vest is simply the best vest on the planet.
i thought my older simms guide vest was the best ever,how wrong i was,the g3 vest will carry all you need for a days fishing.
i fish all the major rivers in scotland and ghillie on a sw scotland river,this is to me the most important item of equipment i need apart from rod and reel.
pockets for everything from fly boxes to camera and phone etc,
another winner from the simms stable

Excellent for the fly-fisherman who loves and has a lot of gear. Review by Jesse

Jesse 3/13/2014

I received this vest as a Christmas present, and WOW!!! The vest is extremely comfortable to wear, as their is added padding around the collar to support your neck. The vest is lightweight and has more than enough pockets to store gear. I am very adamant on taking a lot of gear out on the water, and this vest is perfect because of the large amount of pockets located across the vest. The back of the vest even has a storage area where you can carry even more gear, or pack a coat or light sweater if the weather gets cold. The retractable components of the vest are extremely efficient and allow me to hold spools of tippet, as well as other tools that you will use numerous times while fly-fishing on the river. If you want a high quality vest with lots of storage that will make you feel like you are wearing almost nothing, buy this vest!!!

Slightly overall better than my 10 year old Guide vest except no rings on the sides below the arm holes Review by jimshorts

jimshorts 6/26/2013

My first impression without even looking at the neck tag was "Made in China". The "D" rings are small,cheap and in weird places. Where I really need one to attach my Gear Keeper for my staff isn't there(below the arm holes). The fabric isn't nearly the quality of my old Simms vest. Hard to say why but it's thinner and just not the same hand.The zippers are decent. And there are lots of pockets. The rigid reinforcement helps for access without the pocket collapsing and moving as you try to put something back or take it out. The sticthing is wider spaced at the seams and there is a lack of reinforcement fabric in critical areas. Time will tell if it holds up. I was expecting better. I bought site unseen due to my local fly shop not having any in the store to look at and try on. Simms has a terrific warranty and service department. I know they will stand behind this product even if it isn't of the quality I was expecting.

So much room! Review by Andrew Malek

Andrew Malek 11/8/2012

So I got this vest at the start of the summer fishing season this year and let me tell you it is by far the best vest i have ever owned. With all my other vests I always had problems with storage, either they didnt have enough pockets, not big enough pockets, or just bad location of pockets. With this vest I never had any problems, it was almost hard to fill up all of the pockets. The big seller for me was the fact that I can keep a light jacket on the back pocket for the chilly montana mornings. Buy this vest!
