Base Layer Heaven

    Built-in bra is a must for me. This long bra/tank is the perfect base layer. The material is sweat wicking and quick drying. Super comfortable for all day wear.

    Excited for the long version

    • Familiarity: I've used it once or twice and have initial impressions
    • Fit: True to size
    • Size Bought: Small

    I have several PhD seamless strappy bras and adore them. I just found this long version and am totally stoked. It fits the same and is the same material. It will be perfect for layering this winter and I can also see wearing it to yoga or as a stand alone in the summer.

    Perfect everyday baselayer

    • Familiarity: I've put it through the wringer
    • Fit: True to size
    • Size Bought: medium

    I wear this daily under lightweight to heavy tops for horseback riding in an indoor arena when the temps dip below 50°F. It provides enough light support for my D cups for light riding and afterwards I can continue wearing it alone or layered under a shirt at home. Same goes for skiing or, really, any sport or non-sport activity when the temperature falls below 50.

    The wool keeps me perfectly comfortable in a wide range of temps and I've never ever felt sweaty, even while participating in stop & go activities. It's very soft, stretchy, and comfie and I'm here to stock up on a couple more. Highly recommended base layer that doesn't take up extra room under other garments. True to size chart.

    Long Bra Nirvana Attained

    • Familiarity: I've used it several times
    • Fit: True to size
    • Size Bought: XS

    My life will never be the same. I like the feel of natural fabrics (or natural blends) against my skin and the fact they don't stink like the synthetics. But in the winter cotton blend cami's can be too cool, living in a stone house without central heating. Enter this wool long bra. Most of the time it's buried under layers but if I'm sitting by the fire and get hot I can strip down. It's warm and comfortable. Fits great and looks great. I prefer wearing cami bras and this is the best one I've ever had.

    How to Measure:
    For best results, take measurements over your underwear.
    Measure under your arms, around fullest part of chest and back circumference.
    Measure around your natural waistline, keeping the tape a bit loose.
    High Hip:
    Measure around high hip circumference approximately 3-inch below natural waistline.
    Stand with feet together and measure around the fullest part of the hip.
    Arm Length:
    With elbow bent slightly, measure from center back of neck, across top of shoulder, to elbow and down to wrist bone.
    Measure along inside leg from crotch to ankle bone. Or using pants that fit well, measure the crotch seam to the bottom of the leg.
