Worth spending that bit extra
I love being outside to meditate; however, I don't like the cold. These bad boys add an extra layer of warmth that I really appreciate. Definitely worth spending that bit more.

Guarded score of 5 stars if these will last 10 years othewise 4 stars.
Nogood telling the reader how good this is without referencing to others for comparison so here goes :- In the 1970's to 1980's I used long johns bought from high street stores and also Damart (thermal underwear). These may have been satisfactory for warmth but terrible for dealing with sweat. Since 1979 I have been using Helly Hensen (HH) Lifa (not Lifa Merino (not available then) interspersed with Damart. Lifa is great in handling sweating but didn't provide the warmth of Damart. Around 2010 spent two winters using HH Merino (not Lifa Merino). These gave a good compromise in handlign warmth and sweat. But HH Merino disappeared off the market; guess replaced by HH Lifa Merino. These are great and have been using them for the past 10 years. However, the HH pricing has gone strastospheric. Found anohter brand on Amazon offering merino (only, not like Lifa Merino with synthetic). However, these were very thin and thus disappointed. So came towards end of winter 2024/25 decided to continue searching - realised Merino.tech market 3 different thicknesses of merino base layers. Am happy to report that these 320 gsm (grammes per square metre) ones are the thickest pair of long johns I have tried for couple of decades. They are warm. However, don't reckon they deal with sweat as well as HH Lifa Merino - but then you have to consider the price, which is not £80 for the HH Lifa Merino. In summary, if these Merino.tech long johns lasts as long as those from HH, then these deserve 5 stars but it is too soon to tell. (I have had the HH Lifa Merino for 10 years and I also have HH Lifa (not Lifa Merino) for 20 years ..... so it maybe that spending more will mean longer lasting product. Time will tell but early sign is not comforting because the Merino.tech leaflet says hand wash only for their "Lifetime Warranty". Get Real! I won't have time to hand wash ! No, I will wash as per the way I do with the HH brand, 30 degrees on the wool cycle in a washing machine using non-bio detergent.) I am not born yesterday and I am not going to fall for that "Lifetime" nonsense because "Lifetime" means what ever the manufacturer wants it to mean and it's never as long as the customer expects.

Matière très agréable, chaude, confortable. C'est une laine très fine et délicate. Je l'utilise surtout comme pyjama, occasionnellement comme sous-vêtement. Se lave sous programme laine délicat à 30°C et petite dose lessive extra-douce (Mir Laine) (j'utilise un filet). Essorage à petite vitesse (600t/min) pendant une dizaine de minutes. Suspendre pendant 30 à 40 minutes et il est prêt à lemploi. Attention : pas de séchage à chaud ! Toujours impeccable après une vingtaine de lavages

Questi pantaloni termici sono una calda carezza sulla pelle. Morbidissimi. In lana merino al cento per cento, si possono usare tranquillamente tutto il giorno perché attivano un calore naturale, piacevole e duraturo. Sono anche certificati oeko-tex il che significa che sono senza sostanze cancerogene o pericolose. In omaggio c'è un paio di calzini in lana merino di ottima fattura dello stesso colore del pantalone che completano questo eccellente intimo da uomo. Ne ho già comprati due. Consigliatissimo.

Ich habe die Merino‑Baselayer Hose (Herren) über mehrere Abende auf verschiedenen Weihnachtsmärkten getragen – bei Wind, Nieselregen und Temperaturen knapp über 0 °C. Mein Eindruck: angenehm warm, spürbar trocken und kein Kratzen. Genau das, was man sich unter Jeans oder Thermohose wünscht, wenn man stundenlang draußen steht. Praxiseindruck (real getestet) Wärmeleistung: Hält die Beine konstant warm, auch im Stand – perfekt für Glühwein‑Schlangen und bummelnde Runden. Feuchtigkeitsmanagement: Unter der Winterjacke wird’s schnell warm; an den Beinen blieb es trocken. Schweiß wurde gut abtransportiert, ohne feuchtes Kältegefühl. Tragegefühl: Weich, elastisch und kein Jucken. Sitzt körpernah, ohne einzuengen – unter Jeans unauffällig. Geruch: Nach mehreren Stunden draußen neutral geblieben; ideal für mehrtägige Märkte oder Reisen. Pflege: Nach der Wäsche Form stabil, kein Verziehen; Trocknet vergleichsweise schnell. Verarbeitung & Passform Elastischer Bund und flache Nähte – bequem, kein Scheuern. Länge fällt leicht sportlich aus (bei mir bis knapp über den Knöchel) und passt gut in Stiefel oder hohe Sneaker. Stoff fühlt sich dichter an als klassische Funktionswäsche, bleibt aber beweglich – gut für längere Wege zwischen Buden. Für wen passt das? Pendler & Marktgänger, die viel stehen und frieren vermeiden wollen. Reisende oder Festival‑Besucher, die geruchsarme und schnell trocknende Unterzieher bevorzugen. Kleiner Hinweis (authentisch) Wenn du zwischen zwei Größen liegst, eher die größere wählen – der sportliche Schnitt sitzt körpernah. Für extrem windige Tage empfehle ich zusätzlich eine Windtight oder eine gefütterte Außenhose. Warum ich die Merino‑Baselayer Hose empfehle: Warm & atmungsaktiv für kalte Outdoor‑Events Weich & kratzfrei – angenehmes Hautgefühl über Stunden Geruchsarm, ideal für mehrtägige Nutzung Unter Jeans kaum sichtbar, alltagstauglich Pflegeleicht & formstabil nach der Wäsche Fazit: Für lange Abende auf dem Weihnachtsmarkt und kalte Outdoor‑Tage ist diese Merino‑Baselayer Hose eine sehr überzeugende Wahl. Sie kombiniert Wärme, Komfort und Alltagspraktikabilität – genau das, was man in der Winterzeit braucht.
