Bulk-free warmth for the coldest days.
When it''s bitingly cold outside, layer up with the Under Armour Women''s Base 4.0 Crew. Made with thermal grid fleece, this low-bulk top provides huge warmth without weighing you down. Anti-odor technology fends off funky odors, and flatlocked seams provide a comfortable fit. The fitted design keeps it tight enough pull moisture away from your body, but loose enough that you don''t get the uncomfortable squeeze of a compressive layer. Built-in thumbholes keep the sleeves from bunching when you layer over this top.
