The Sierra Designs DT Tech Jacket is a stylish, athletically cut rain jacket. It is built with Entrant DT - one of the more breathable of the lightweight waterproof PU-coated fabrics on the market. This fabric is textured on the interior face for improved comfort against bare skin. For times when the fabric cannot breathe sufficiently for the workout, the Tempest has a variety of easy-to-use ventilation options to keep air circulating. This jacket has a simple, usable hood and one-handed cordlocks at the neck and waist. The downfall of the DT Tech Jacket, however, is in its waterproof zippers; after a short period of time, the polyurethane coating began to delaminate and peel, allowing water to enter the jacket and making the jacket appear worn out before its time. A poor DWR finish appears to inhibit breathability in wet conditions.
