Bien mais jambe large
Review by Sonia C. on 22 Feb 2024 review stating Bien mais jambe large
J’ai acheté ce modèle à mon conjoint. Le tissus est d’une excellente qualité mais il le trouve trop large à la jambe et l’élastique à la taille est aussi trop large à son goût. J’ai dû le garder car par de retour possible pour cet achat.

Great fit
Review by Derek R. on 20 Feb 2024 review stating Great fit
I really like the way these fit - they're not too tight but aren't loose like some merino boxer briefs are. Plus all the benefits you get with merino wool.

My husband says these are amazing. They don’t ride up. They wash well. They breathe.

Great merino boxers

I've been purchasing these boxers for a few years now. They are very comfortable and have been holding up well after many washes.

Very Comfortable
Review by Edmund M. on 30 Jan 2025 review stating Very Comfortable
I was worried about the fit, and I was surprised at how comfortable this was. I purchased the long tights along with these boxers, for long thu hikes. Lightweight, dries fast when washed and air dried, and pretty much odourless when worn for multi day hikes.

Luxurious Tights
Review by Zachary K. on 27 Jan 2025 review stating Luxurious Tights
While these do cost a pretty penny, they certainly provide a top tier product. I can't speak to their longevity, but the comfort, fit, skin feel, and odour-fighting qualities are like manna from heaven.
