Description
Two-Layer Wool Long Johns with Elastic Waist, Anti-Microbial
Product Overview
A two-layer union suit covers waist to wrist, but workers layering under bibs need insulation below the belt only. The Stanfield's 8812 Two-Layer Merino Wool Blend Long Johns deliver trapped-air warmth in a bottom-only cut. These wool blend thermal long johns pair a cotton-poly inner with a merino-poly outer. Anti-microbial treated, elastic waistband, roomy seat. Sizes S through 3XL. Made in Canada.
Key Features
- Elastic waistband, plush back, roomy seat for all-day comfort under work pants. The waistband sits flat under bibs and the roomy seat gives full range of motion, so these two-layer wool long johns move with the body during squatting, climbing, and kneeling.
- Two-layer jersey knit, trapped-air insulation, lighter than single-layer wool. A pocket of still air between the two fabrics insulates body heat, and this two-layer merino long johns design delivers that warmth at lower fabric weight.
- Merino-poly outer layer, 50/50 blend, natural temperature regulation. The merino releases heat during movement and holds it during rest while polyester adds durability, so this merino wool blend long underwear manages both warmth and moisture across shifting temperatures.
- Cotton-poly inner layer, 50/50 blend, soft against skin. The inner fabric feels like a cotton base layer but wicks moisture toward the merino, so buyers stepping up from cotton thermals to wool blend thermal long johns keep the comfort they know with improved heat retention.
- Anti-microbial treatment, extended freshness between washes. Agents in the fabric limit odour-causing bacteria, so workers on consecutive shifts or multi-day assignments keep anti-microbial long underwear in rotation longer than untreated alternatives.
- Made in Canada, Truro, Nova Scotia, sizes S through 3XL. Every 8812 is knitted in the same mill that produces the 8800 and 1300, and this range of Canadian made wool long johns extends to 3XL, one size beyond the 8800's 2XL limit.

Sizing & Care
Sizes run S through 3XL in Charcoal Mix. The 8812 extends one size beyond the 8800 union suit, fitting frames up to 3XL. Order your regular size.
Turn the garment inside out before washing. Machine wash cool with similar colours. Do not use bleach or fabric softener. Tumble dry on low. Iron on low only if needed. These steps protect the merino outer layer and preserve the anti-microbial treatment.
For full-body coverage in the same two-layer fabric, the 8800 Two-Layer Union Suit covers waist to wrist with a full button front and trap door, in sizes S to 2XL.
For 100% merino in a long-john cut, the 8312 Pure Merino Wool Long Johns use single-layer merino for buyers who want all-wool next to skin, in sizes S to XL.
Applications

Frequently Asked Questions
What is two-layer long underwear and how does it insulate?
Two-layer long underwear uses two separate fabrics with an air pocket between them. The trapped air insulates, holding body heat the way a thermos holds temperature. Still air between an inner and outer layer does the insulation work, not fabric thickness.
What is the difference between two-layer long johns and a two-layer union suit?
Coverage area. In a two-layer long johns vs union suit comparison, Stanfield's two-layer long johns cover the waist and legs only. The 8800 Two-Layer Union Suit covers waist to wrist as a one-piece garment with button front and trap door. Long johns pair with a separate top for layering flexibility.
How do you wash merino wool long johns?
Turn the garment inside out before washing. Machine washes cool with similar colours and avoids bleach and fabric softener. Tumble dry on low. Knowing how to wash merino wool long johns correctly preserves the anti-microbial treatment and extends the life of the merino outer layer.
What are the best two-layer long johns for cold weather work?
Two-layer wool long johns with a merino outer layer balance warmth, moisture management, and odour control for cold weather work. The 8812 adds anti-microbial treatment and an elastic waistband for all-day comfort under coveralls. These are Canadian made wool long johns from Truro, Nova Scotia.
How do merino wool long johns compare to synthetic base layers?
Warmth source and odour control. In a merino wool long johns vs synthetic base layer comparison, merino fibre regulates temperature naturally and resists odour between washes. Synthetic base layers dry faster but hold smell and need more frequent laundering. Stanfield's two-layer long johns add anti-microbial treatment for extended wear.
