Modal Long Sleeve Baselayer
Lightweight, warm, long sleeve baselayer for spring and autumn riding.
Super lightweight knit with open perforated structure for efficient moisture wicking and high breathability. Modal, originally developed in Japan as a substitute for silk, is extremely comfortable, soft and retains its elasticity even after repeated washings. Micromodal beech cellulose fibers are compostable and biodegradable. Polyamide increases the strength of the fabric and improves its durability despite its light weight. Flat seams for maximum comfort in contact with the skin.

Effective for deep winter ride
I ran for two hours in -2°C with strong winds wearing a combination of a modal base layer, an alternative winter long-sleeve shirt, and a softshell jacket. Despite being incredibly warm, I barely broke a sweat. With other base layers, after just an hour, sweat that doesn't dry completely causes localized chills. Modal seems to offer high breathability and insulation, leaving no sweat on the skin.Show full review -

Just what you need
I’ve been using the merino 250g base layer but I’ve noticed it’s been a bit too warm more often than not when it is not cold enough outside, so I realized I needed a thinner base layer piece, and where to get it from if not from isadore. Never been disappointed with their products, they same a friendly customer service and Designs are timeless. For 1.85m and 82kg I went for an L because I like my lower back to be well covered but M would fit excellent as well if you’re wonderingShow full review -
