Men's Thorpe Baselayer

Regular price £69.99
/

Trail-Ready Comfort. All-Day Performance.

Pre-Order the Thorpe Ultra-Fine Merino Baselayer

It's built for trail runners who demand comfort, performance, and versatility in all conditions. Crafted from a premium blend of 68% superfine Merino wool (17.5 microns) and 32% TENCEL™ Lyocell, this lightweight layer delivers exceptional softness, breathability, and durability.

Whether you're climbing, descending, or spending long days in the hills, the Thorpe regulates temperature and wicks moisture to keep you dry and comfortable. Merino wool stays warm even when wet and naturally resists odour. TENCEL™ enhances cooling and quick-drying properties, making this baselayer ideal for both warm and cold-weather running.

Pre-Order Info - The baselayers are due to arrive with us wc 3rd November. You will be notified with your Royal Mail tracking number by email as soon as your order is dispatched during that week. See full pre order details further down the page.

Key Features

  • YKK® half zip for adjustable ventilation
  • Flatlocked seams for chafe-free comfort
  • Thumb loops with cosy fold-over mitts
  • Lightweight: approx. 199g (men’s medium)
  • Versatile: wear solo or layer under waterproof shells

Why It Matters

“A lot of people assume baselayers are just for warmth. But almost anything will keep you warm. The real test comes when you’re working hard and sweating. Because sweat is inevitable. What matters is how your kit handles it.”

- Dan Summers, Harrier Technical Advisor

Picture the classic trail scenario: you're grinding up a climb, building heat. Then you stop. You take a drink. Suddenly you're freezing. Your baselayer is damp, clinging to your skin, and pulling the warmth out of you.

The Thorpe blend is engineered to:

  • Wick moisture fast
  • Stay warm when wet
  • Breathe and dump excess heat
  • Feel soft and natural against your skin—all day long

Good kit is for everyone, and you deserve it for your trail running. A quality baselayer means fewer layers to swap, fewer stops, and more time moving well on the trail.

FAQs

How much does it weigh?

Approx. 200g for a men’s medium (weight varies slightly by size).

What is it made from?

68% superfine Merino wool (17.5 microns) and 32% TENCEL™ Lyocell, made in the EU.

How do I wash it?

Machine Wash: Use a delicate or wool cycle.
Temperature: Wash cool, ideally at 30°C.
Detergent: Use a mild, neutral-pH detergent made for wool (we recommend Grangers Merino Wash). Avoid enzymes, bleach, and harsh chemicals.
Wash Separately: Wash inside out and separate from dark or rough fabrics.
Avoid: Do not use fabric softeners.

Drying & Care:
Air Dry: Lay flat on a towel or drying rack, in a shaded and ventilated area.
Tumble Dry: Not recommended. If the garment label allows, tumble dry on low heat only.
Prevent Pilling: Washing inside out helps reduce friction.
Stains: Rinse promptly with cold or lukewarm water.
Storage: Store in a cool, dry place away from sunlight.

What size should I choose?

Choose your usual running top size for a close, next-to-skin fit. If you prefer a looser fit or want extra room for layering, consider sizing up.

If you need something sooner, please place two separate orders.
