Product Insights
Responsible Merino Wool Mock-Neck Sweater Regular, close-fitting fine-gauge cut; take your normal size for solo wear, or size up to layer over a collared shirt. Breathable fine-gauge merino that regulates body heat via crimp-trapped air and moisture buffering. Light-but-warm fine-gauge weight suited to wearing alone in a heated office or under a coat, not as a sole winter layer. Flat 99 CAD across all 29 variants, with no colour or size premium. Thin fine-gauge knit is not a standalone winter sweater; best as a layering piece under outerwear.
Verified claims
- fit
- Regular, close-fitting fine-gauge cut; take your normal size for solo wear, or size up to layer over a collared shirt.
- sizing
- Medium is cut for a 38–40 in chest, large for 41–42 in; the brand publishes body measurements rather than garment measurements.
- comfort
- Ultra-soft 100% merino against skin; fine fibre diameter is the main reason it feels soft rather than prickly.
- material
- Breathable fine-gauge merino that regulates body heat via crimp-trapped air and moisture buffering.
- layering
- Light-but-warm fine-gauge weight suited to wearing alone in a heated office or under a coat, not as a sole winter layer.
- neckline
- Short stand-up mock collar gives turtleneck-like coverage with less bulk and easier layering.
- construction
- Finely ribbed collar, cuffs and hem; set-in shoulders and a smooth fine-gauge stockinette body.
- styling
- Minimal, logo-free mock-neck silhouette; dark neutrals read business-casual, while earth tones and baby blue lean more casual.
- colour
- Six colourways: Black, Slate Grey, Brown, Mossy Green, Navy/Midnight Blue, Baby Blue.
- sizing
- S–XXL across most colours; Baby Blue stops at XL, so XXL buyers choose from five colourways.
- value
- Flat 99 CAD across all 29 variants, with no colour or size premium.
- care
- Machine wash inside out cold delicate, ideally in a mesh bag; lay flat to dry, do not bleach, low iron inside out if needed.
- durability
- Fine-gauge merino can pill at friction points like underarms over time; a fabric shaver clears it in a couple of minutes.
- care
- Reshape while damp and dry flat; never hang a wet fine knit.
- material
- Merino manages moisture and odour, and its moisture absorption helps reduce static cling.
- composition
- 100% merino wool knit sourced from certified responsible farms.
- sustainability
- Part of a responsible wool collection; wool sourced from certified responsible farms.
- tradeoff
- Thin fine-gauge knit is not a standalone winter sweater; best as a layering piece under outerwear.

Product comparison
Compared within this brand.
| Responsible Merino Wool Mock-Neck Sweater: Choose this if you seek an exclusive, Canadian-designed sweater crafted from ultra-soft, 100% merino wool sourced from certified responsible farms. This fitted, long-sleeved piece features a short mock-neck with fine ribbing and a smooth, fine-gauge knit that regulates body heat and offers a tailored appearance. While ideal for fine wear, remember to care for it by machine washing inside out on a delicate cycle and laying it flat to dry.[1,2] | Tencel™ Modal And Organic Cotton Mock-Neck Sweater: Choose this if you want a lightweight, soft knit in a blend of 60% organic cotton and 40% TENCEL modal with a ribbed mock neck and slim profile for layering under blazers or jackets—reviewers report it works well for office and smart-casual wear without bulk. Fit is described as true to size and comfortable, with a non-sagging collar and colors reported to match the online photos. Note that sizing can be inconsistent across colors and batches—some reviewers found sleeves and body too short on taller frames—and pilling plus seam damage are reported with regular machine washing, so delicate or hand washing and air drying are advised.[3,4,5] | Muted Ribbed Sweater: Choose this if you want a textured, chunky crewneck sweater with a muted two-tone charcoal melange look from vertical ribbing. It is made of 100% reprocessed cotton, offers a shallow crew neck with a narrow ribbed collar, and has a straight torso fit with ribbed cuffs and hem. It comes only in Black and in Small and Medium sizes, so it will not work if you need other colors or sizes.[6,7,8,9] |
