Coats and jackets, made for British weather

Theseca is an online shop for outerwear, serving customers across the United Kingdom. We sell one category and we sell it properly: jackets and coats for women and men, built for the winters we actually get.

What we do

British weather is not extreme, it is persistent. Rain that lasts all week, wind that finds every seam, a commute that starts and ends in the dark. That is the brief we buy against.

Our focus is deliberate. Because we stay with outerwear, we can spend our time on fabric, fit and finish instead of stretching across a catalogue that tries to cover everything.

How we choose what we sell

  • 01 — Weather first

    Weather resistance that holds up in rain and wind, taped seams where they belong, and linings that keep warmth in without adding bulk.

  • 02 — Built to hold its shape

    Outerwear is worn hard, day after day, for months at a time. Zips, buttons, cuffs and pockets are the first things to fail, so they are the first things we check.

  • 03 — Still right in three winters

    We stay away from styling that dates in a season. Clean lines, restrained colour, nothing that only makes sense this year.

  • 04 — Honest sizing

    Outerwear is worn over other clothes, and that changes how it should fit. Every product page carries a size guide for that specific cut.

Fabric, fit and the details

Wool blends that hold warmth at a low weight. Wind and water repellent outers for the days that need them. Down that keeps the heat in without the bulk.

Fit varies between cuts and fabrics, so every product page carries its own size guide. If you are between sizes, email us before you order and we will give you a straight answer. If it still is not right when it arrives, our Return and Refund Policy explains exactly how to send it back.

How we work

Delivery is free on every order, anywhere in the United Kingdom, with no minimum spend. Prices are shown in pounds sterling and include UK VAT where VAT applies, so the price on the page is the price you pay.

You can reach a person Monday to Friday, 09:00 to 17:00 (UK time), and we aim to reply within 24 hours on business days. Our full company details are on our Contact page.
