 Warranty Information

The Wiggy's sleeping bag guarantee is for a lifetime of use. If a seam opens or the Lamilite insulation deteriorates (such as losing its loft or separating, clumping in one place or another), Wiggy’s will repair or replace your bag at no charge. However, we reserve the right to examine any returned sleeping bag and will make the decision whether the return is justified depending on the appearance of the bag, demonstrating whether it has been properly cared for or shows signs of abuse.

 Product Description

The Ultima Thule is a -20º F (-30º C) rated mummy style bag. It is available in our four standard sizes, though I recommend the wide width due to the fact that there is double the insulation on the top half of the bag.

When the Overbag is added to the Ultima Thule, the temperature rating becomes -60º F or C. When both bags are combined, you have the Ultima Thule FTRSS.

Product Testimonials

  1. Simply the best!!!

    I have been a faithful Wiggy's customer for going on 30 years. Back in the 90's I ordered an Ultralight and a Ultima Thule and was far beyond pleased with both of them. Still have the Ultralight but sold the Ultima Thule because of the spare tire I have acquired over the years. 3 weeks ago I ordered another Ultima Thule in a regular/wide body and couldn't be happier with my purchase! Have you noticed the decline in sleeping bag manufacturers over the years? Have you noticed that Wiggy's is still around and still going strong? The reason is consistency and quality! Save yourself the trouble and disappointment of purchasing from another maker and buy a Wiggy's bag!!!

  2. awesome sleeping bag...

    I bought this bag with the intention on using it on the Appalachian Trail. I was on the Trail March2nd, 2018 and this bag was a life saver. Granted it’s a heavy bag and that is something I was ok with. We had 40mph winds and temperatures below 20 degrees. Before the wind chill was included.

    I saw so many hikers beyond cold. Not me...I stayed toasty warm. I’m not a tall guy at 5’10” and weigh about 260 lbs. I was doing a night hike where it was so cold the water bottles froze. I was close to hypothermia from all the sweating I did and this bag saved my bacon. Best bag I’ve ever had.

  3. great bag

    I have had this bag over 2 years and sleep in it often. Well made, super warm, have yet to need the over bag (already purchased) during my overnights in the PNW. I use the overbag for summer nights. Saving money for the Ducksback products and the freedom shelter.
