- + Optional 3mm boots
Surf & watersports
Cool water — the classic UK/Atlantic spring or Pacific Northwest summer range. A 4/3mm sealed-seam suit keeps you in the water for 90+ minutes. Boots prevent foot pain on rocky entries and extend session length.
Open-water swimming
Acclimatised swimmers manage 30 minutes; a thicker swim wetsuit (3/2) helps.
Recommendation tuned for Keem Bay's current water temperature. Individual tolerance, wind chill, and session length all matter — when in doubt, size up.
