Three is a good number. You’d wear these jackets on a casual outing, stroll around the park, or on the plane as a cover-up layer. The jackets I’ve curated are fairly lightweight, but also versatile and subtle.
- The olive-green technical jacket – rainproof and indestructible. This is my go-to throw on jacket when I need something feather-light and low maintenance. Could be vintage or a brand such as a Barbour or Purdey.
- Harrington jacket – the Baracuta G9 is classically predictable. It’s waterproof, yet stylishly warmer than the technical jacket. I prefer neutral as a color (as below). Neutral provides contrast to your dark olive jacket and the third jacket.

3. Suede jacket – slightly shaped like the Harrington jacket, but attracts a different look with the suede leather. Chocolate-brown suede looks textured and rich, yet subtly relaxed.

As a continuation, I also like corduroy, safari, and Lazyman jackets; many brands such as The Anthology (below) offer a wide range of casual jackets. These are more unusual, however, and I would stick to the basics first before plunging into other styles.
