The very best dry top IR has to offer, and perhaps the driest top on the market today. The X-Jacket is based on the same platform as the Comp LX, but all of the major body seams are glued and taped instead of stitched. This allows for zero seam bulk under the seam tape (especially at cross-seams), thereby creating 100% contact between seam tape and garment. As of yet Immersion Research is the only paddlesports company offering this very special construction in a dry top, and the 2011 version is the best yet- the result of over 5 years of refinement.
