"What Our Gearhead® Experts Are Saying: ""This is the jacket I grab when the weather can’t make up its mind. It’s warm without being bulky, blocks wind really well, and the fleece lining makes it super comfortable to wear over just a tee. The shell shrugs off light rain, and the cuff and hem knit trim really help lock in heat. Great everyday layer for shoulder seasons."" We count on the L. L. Bean Warm-Up Regular Jacket for reliable comfort through shifting shoulder-season weather. Built with a durable nylon shell treated to resist wind and light rain, this jacket keeps us protected on commutes, weekend walks, and cool-weather travel. Inside, the soft fleece lining in the body and collar adds instant warmth without the heaviness of a full winter coat. For added comfort in chilly conditions, the sleeves are lined with smooth taffeta and insulated with 3M Thinsulate to hold in heat while maintaining easy mobility. Zippered hand pockets keep our hands warm and essentials secure, and the rib-knit hem and cuffs help seal out drafts. From mild spring outings to crisp late-fall days, this versatile jacket becomes an essential layer we reach for again and again."
