Buy the Large for your Model 639 →Why inflatable instead of foam?
- No foam core — it can never absorb water or grow mold, so it stays 35–40 lb for life
- Welded drop-stitch construction, the same build as inflatable paddleboards
- Insulates with trapped still air that can't lose R-value to moisture
- Includes the pump, three ZipTech™ skirt depths and four keyed locking tie-down straps
