Icebreaker 200 Oasis Leggings Men's
I hated wool until I got Icebreaker merino garments. They're awfully close to cotton in comfort and I totally forget I'm wearing wool base layers. I got the thickest ones I could find: Anatomica T-shirt plus 260gm Tech long sleeve on top, 260gm Tech pants, all under my Fusion undergarment. I think the Oasis is just the thinner version (200gm). The long sleeve shirt is my favourite.
The 260gm pants feel like thinner material than the 260gm top, which seems odd. They can also snag and get holes if you're not careful. But they are nice and warm, don't smell, and dry pretty quickly. They are meant to be worn under something, but often I'll drive out to the dive site and dive shop in them. They've gone probably 200 dives and have lasted well, with just a small hole from snagging on my twinset bolts while lifting.
