Description
Warmth is crucial in cool weather – make the fun last longer with these breathable, insulating baselayers. They have a unique mesh structure on the reverse of the fabric that moves moisture to the outside for super efficient moisture management.
- Made of 100% recycled polyester.
- Super stretchy for added comfort and easy on/off.
- Flat seams don't chafe or add bulk, so they're good for layering.
- Classic pull-on design with an elastic waist.
- Gussetted crotch for ease of movement.
- Heat transferred label is comfortable against skin.
Fit guide
Technical garments, designed for specific activities have features that aren’t always adaptable to general use. For example, cycling clothing is longer in the back and arms. Activity aside, the fit of MEC clothing falls into these categories:
Tight, with no room to spare.
Very close fit, with a bit of room.
Generous, but not oversized.
Oversized with lots of room for layers.
All MEC men’s and boy’s pants are regular rise.
