Cozy Fleece Crew - Porcupine

Owners report James Perse's numeric sizing (0=XS up to 5=XXL) runs true to size, with a deliberately relaxed, California-casual cut rather than a slim one.

Reviewers and sizing guides agree the numbered sizing maps predictably to standard sizes and stays consistent across tees, tanks, long sleeves, and sweats — one long-term owner wears the same size 1 across every James Perse product she owns. The caveat owners flag is that the house cut is intentionally roomy: tees and sweats read slightly relaxed at your true size, so people wanting a trim fit sometimes size down, while button-ups and polos can wear looser than the marked size suggests. On the women's side, fitted jersey pieces are the exception — reviewers note the skinny and fitted styles run small, and pants are cut long.

Sizing advice: Take your usual size converted to the number scale (0=XS, 2=M, 3=L); size down only if you want a trim fit in the relaxed tees and sweats, and size up in fitted jersey styles.

Third-party coverage of the sweats line specifically is thin — most owner reports concern the brand's tees and jersey basics, and the same themes recur across them. Owners like how the pieces look and sit on the body but repeatedly question durability: one owner reported a sweatshirt developing a hole after 40 days, others describe shrinkage after a single wash and holes appearing within months. Long-time buyers on Styleforum add that fabric weight shifts between production runs, so thinner batches wear out faster. A common refrain is to buy on sale rather than at full price.

Strengths

Owners consistently praise the softness and the way pieces look and sit on the body when new.

Watch out for

Fabric fragility is the recurring complaint — holes within weeks to months, shrinkage after washing, and batch-to-batch variation in fabric weight.

Sizing

Owners report shrinkage after machine washing the lightweight cotton, so wash cold and air-dry rather than counting on the bought size staying put.
