What Gear Do You Actually Need for Wild Swimming and Cold Plunges?

One of wild swimming's greatest appeals is how little you need. A swimsuit and a towel, and you're in. But as you progress into colder water and longer sessions, the right gear dramatically improves both safety and enjoyment. Here's what actually matters — and what's marketing fluff.

Essential Gear for Every Wild Swimmer

Changing Robe / Dry Robe

This is the single most impactful piece of kit you can own. A well-insulated changing robe lets you strip out of a wet swimsuit and into warm layers without exposing yourself to cold wind — a major hypothermia risk after a cold plunge.

Top picks: Dryrobe Advance (£185 / $230) remains the market leader for warmth. For budget options, the Decathlon Nabaiji Changing Poncho (£40) does the job. The key spec: fleece lining weight. Look for at least 300 g/m².

Tow Float

A tow float is a non-negotiable safety item in open water. It keeps you visible to boat traffic and gives you something to rest on if you tire. In the UK, the Outdoor Swimming Society recommends one for all open-water swimming. Costs from £15 — there is no good reason not to own one.

Neoprene Swim Cap

Up to 40% of body heat is lost through the head in cold water. A standard latex swim cap does almost nothing against 10 °C water. A 3 mm neoprene cap extends your safe immersion time meaningfully and reduces the headache-inducing shock of cold water on your scalp. Budget around £15–30.

Intermediate Gear (Once You're Going Regularly)

Wetsuit vs. Skins

This is the great wild swimming debate. Skins swimmers (no wetsuit) argue you lose the full cold-water stimulus and skin sensation. Wetsuit swimmers argue you can swim longer, safer, and explore more spots year-round.

The pragmatic answer: use a 3:2 mm wetsuit (3 mm torso, 2 mm limbs) for water below 12 °C if you want to swim for longer than 15 minutes. For cold plunges under 5 minutes, skins is fine and arguably more effective. A mid-range open-water wetsuit from Zone3 or Orca runs £120–200.

Neoprene Gloves and Booties

Hands and feet lose sensation fastest in cold water. Below 10 °C, neoprene gloves (1.5 mm) extend your safe window considerably and make the after-experience far more pleasant. Booties also protect feet on rocky entries — a practical safety item as much as a warmth tool.

What You Don't Need

• Expensive waterproof headphones — you're in cold water for 3–15 minutes; you don't need a soundtrack
• Hydrodynamic racing wetsuits — designed for triathlons, not cold plunges; they lack thermal insulation
• A fitness tracker for your swim — useful eventually, but zero impact on safety or experience when starting out

The Gear That Costs Nothing: Good Information

The most underrated part of any wild swim kit is knowing what you're getting into before you arrive. Water temperature, current speed, water quality reports, and notes from swimmers who were there yesterday are worth more than any piece of neoprene. Our app gives you all of that for every spot in our database — so you can pack the right gear for the actual conditions, not your best guess.
