If you’re on Oʻahu, REI is probably your best bet for a merino wool base layer. They currently have a large selection from Smartwool, Icebreaker, REI Co-op, Arc’teryx, and others.
REI Co-op Merino 185 — excellent value; lightweight, good for travel/hiking. There are currently sale prices around $40 on some versions.
Smartwool Classic Thermal Merino — my pick if you want a warmer, traditional base layer. REI currently has men's and women's versions, with some on sale.
Icebreaker Merino 200 Oasis — another excellent option, especially for colder-weather travel.

REI — probably the best one-stop shop. They carry Smartwool, Icebreaker, and REI Co-op merino layers, with 242 merino base-layer options currently listed.

Icebreaker — one of the original merino specialists. The 200 Oasis is a great all-around choice.

For general cold-weather layering, I'd look for 175–200 gsm merino. It's versatile without being excessively thick.
For skiing / very cold weather, go 250–260 gsm. Icebreaker's 260 line and Smartwool's Thermal Merino are good choices.
And there's a particularly good deal at REI right now: some Smartwool and REI merino base layers are marked down substantially as part of the current Labor Day sale.
