icebreaker Men's Base Layer

icebreaker Men's Base Layer — X-Boundaries Singapore

Nature's Answer to High Performance.

Born in New Zealand, icebreaker pioneered Merino wool as the ultimate performance fabric — and their men's base layer collection is where that philosophy shines brightest. Naturally temperature-regulating, moisture-wicking, and odour-resistant, icebreaker Merino base layers keep you comfortable whether you're on a mountain trail, a long-haul flight, or a weekend trek.

Choose from a range of fabric weights to match your activity and conditions:

• 150–170 gsm Ultralight — All-season versatility for warm to mild conditions
• 200–230 gsm Lightweight — Ideal for moderate to cool temperatures
• 260–280 gsm Midweight — Best suited for cold conditions and layering
• 320–380 gsm Heavyweight — Maximum warmth for the coldest environments

At X-Boundaries, we carry icebreaker's full range of men's Merino base layers — tops, bottoms, and zip necks — available in Singapore with fast local delivery.

Base layer starts next to the skin. Men's Anatomica Merino boxers and briefs are included in this collection. For the complete range, including women's Siren and Sprite styles, browse our icebreaker underwear collection.
