Every serious sailor eventually faces this decision. The three dominant British sailing clothing brands each make offshore-rated foul weather jackets in the £300–600 range. They all look good on a chandlery hanger. But how do they actually perform when you're on the helm at 0200, spray flying, with the French coast somewhere to port?

I wore each jacket for a full season passage — St. Helier to Cherbourg, the Race of Alderney, overnight to Dartmouth — before writing this. That photo is the Musto HPX on the backstay as we came into St. Peter Port. It was raining.

Test Conditions

Channel Islands passages, May–September 2025. Conditions ranged from flat calm to Force 7 gusts on the Race of Alderney. All jackets tested at the helm and below, wet and dry, day and night.

The Verdict

Musto HPX Gore-Tex Jacket
Best waterproofing. After four hours on the helm in breaking seas, the inside was bone dry. Gore-Tex Pro fabric, properly taped seams. The gold standard — and priced accordingly.

Gill OS3 Coastal Jacket
The surprise winner on value. At £320 it's the cheapest of the three, but the fit is excellent, pockets perfectly placed, and it kept me dry in everything the Channel threw at it. Best all-rounder.

Henri Lloyd Fremantle Offshore
The one you'll want to wear into St. Helier for dinner after. Genuinely handsome, performs offshore, and the cut and finish is exceptional. Waterproofing slightly behind Musto but not by much.

The Island Skipper's Pick

If money is no object, the Musto HPX. If you want the best combination of performance and value, the Gill OS3 Coastal is genuinely hard to beat — and the £275 you save buys a lot of diesel.
