Frogg Toggs - company report/comment.
The zipper on my HB is a tad tough to start after a few trips (I may even be the culprit.....), so I emailed them and asked how much to replace. They quickly replied back that they would warranty it (although it's slightly out of warranty period and I don't know where my receipt is anyway). I asked if there was anyway to upgrade to their new jackets - sure say they, $40 upgrade fee and I'm good to go! Since I'm in Canada, no need to send the old jacket back, just cut the tags off and send them in with the return authorization (so the cost of a stamp vs. the cost of courier/package to return).
I was already sold on the quality/price of their products - THAT warranty offer and quick, friendly correspondence sealed the deal - can't say enough good things about Frogg Toggs!!
Based upon the comments in this thread, last November I bought a Froggs Toggs Hellbender wading jacket. It got use in the light rain a few times in the past year, but in early November of this year I was fishing in a solid heavy rain for 2-3 hours. I had the hood up, the neoprene cuffs cinched tight, but both sleeves of my sweater were soaked from armpit to wrist.
I emailed Froggs Toggs, explained the circumstances and expressed my disappointment with the product. I got an immediate reply and was asked to ship the jacket back for a warranty inspection. Then a couple of days later I got a second email saying that they were just going to replace the jacket and send me a new one. They wouldn't have my size available until Spring, 2017 and would ship it out then, and was I OK with that? I was/am.
Now, we'll see what happens in the spring, but I was very impressed with the offer to replace the jacket sight unseen, and based upon my word. Heck, I even think they are going ship it to my home and save me a trip to a US freight forwarder.
Very satisfied with the unexpected level of service.
