What a Gi! The Aerolight jacket is a very breathable and comfortable gold weave. Just the right blend of durable and lightweight. Always innovating, Reevo has added vented panels to the underarm... helping to keep you comfortable and dry. White contrast stitching is used sparingly, not everywhere, adding a subtle touch to this patchless jacket. Instead of patches, there are high quality hold embroideries carefully placed (Kanji on the lapel, Reevo logo around the left side vent). Seams are covered, which helps prevent loosening and fraying after repeated use.
