Simms waders have been discussed several times. Here's some feedback.
My G3 waders are several years old now. During this spring's Yakutat trip I noticed I had a small pinhole leak at a seam intersection where the vertical and horizontal seam tapes met. Nothing that ruined the day, just a gray spot when I took them off. I made contact and returned the waders. Simms replaced both booties and gravel guards, re-taped two worn areas, one of which was the leak source, replaced the wading belt, and replaced the suspender clips. Nothing was their fault. These waders are well worn. I had washed them prior to returning them but when I got them back they looked absolutely brand new. I had to inspect them pretty hard to find that they were indeed mine and not a new pair. Pretty good service. Total cost for the repairs and shipping? $47.00. And all I returned them for was a pinhole leak at a wear point. Once again, Simms has impressed me. And I was already a fan.
