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 to you.
At this time, I know of no sleeping bag manufacturer that would even consider such a guarantee. The reason is simple: they already know the insulation they use will deteriorate. If you have ever compared information from the different sleeping bag manufacturers, you will see that they have never guaranteed the insulation they use, nor do they now.
