From his Testimonial page on hs website...
As you know from recent email conversations, I have been using your sleeping bags since the mid 90's. I have used the Ultima Thule/Overbag combination on countless trips from mountaineering to hunting in all temperatures. I mostly used the overbag alone - it has been my favorite bag for backpacking and river trips. I finally had a problem with my overbag after about 15 years and contacted Wiggy's to see about repair or replacement. I was expecting the company to replace the bag for a cost and I would have had no problem purchasing a full price replacement. The problem with the bag was most likely my fault.
Mr. Wigutow replied to my email and said to please send the bag in and he would take care of me - and he did by replacing the bag at no cost to me. Wiggy's has the best customer service of any company I've used - hands down. I very much recommend the bags for all use and especially for people who use their gear regularly and want a product they can use for many years. I also like the fact that Wiggy's is an American company and an American manufacturer. Hats off to Wiggy's.
