Every piece is built in our own shop.
Built once. Used for decades.
One insulation. Everything we make.
Most bags stitch right through their insulation. Every seam is a cold spot. Wiggy's Lamilite is one continuous layer with nothing stitched through it. It breathes, keeps working when it gets damp, and dries fast.
- For families: no cold spots, so everyone sleeps warm.
- In the field: keeps insulating when it's wet.
- For programs: in service for decades, not seasons.
- At the edge of the map: rated to -60°F.
