Alpha Shell Jacket - Lunar Grey

Alo Yoga has no single fit: loungewear (hoodies, sweatshirts, sweatpants) runs deliberately oversized, leggings sit roughly true to size with style-by-style swings, and compressive pieces feel snug.

Owners consistently describe the sweats side of the line as roomy by design — one try-on reviewer notes "many of their clothes are oversized" and kept her usual medium sweatpants for the baggy look while an XS gave a fitted one, and a shopper quoted in a sizing roundup said "i would def go smaller in the bottoms i have found them to run a little big." Leggings are the steadier part of the catalog: multiple reviewers call the Airlift true to size, though a retailer's fit guide advises sizing down in most other legging styles because they cut generous and long. Compressive styles pull the other way — reviewers report snug waistbands and bras, with size-ups common in tight shorts and mesh bras. The recurring owner refrain is that sizing is inconsistent enough across pieces that per-item fit notes matter more than a house rule.

Sizing advice: Take your usual size in Airlift leggings, size down in hoodies/sweatpants unless you want the full oversized look, and size up in compressive shorts and bras if you're between sizes.

What's my size at Alo Yoga?

Reviewers describe Alo's jackets as athleisure outerwear first and technical gear second — warm and light enough for everyday wear and travel, but not built for harsh weather. Recurring owner complaints across the range are pilling after repeated wear or washing, occasional loose stitching, and inconsistent quality control. Fit is intentionally oversized on most styles, and reviewers with smaller frames found the heavier sherpa-lined pieces bulky and restricting.

Strengths

Reviewers consistently praise warmth without much weight — one try-on reviewer's favorite puffer was singled out as warm yet light enough to layer over thick sweaters.

Watch out for

Pilling after repeated wear or washing is the most-reported failure, followed by inconsistent quality control and limited weather protection relative to technical outerwear.

Sizing

Most styles run intentionally oversized for layering — reviewers on smaller frames wished for smaller sizes, and owners commonly suggest sizing down if you don't plan to layer.
