Weighing just over 50 grams, it feels barely there but still delivers full coverage, thanks to a wide, structured brim that holds firm in blustery conditions. As someone who wears glasses, I appreciate how the brim keeps rain off my lenses without needing a hoodespecially during light showers where a jacket would be overkill.The waterproof fabric has easily handled steady drizzle and sharp downpours, and the fully taped seams have kept the interior bone dry. Despite the protection, its breathable enough to wear while on the move without stewing inside. The adjustable rear cinch gave it a secure, dialled-in fit, and it packs down to the size of a buff, making it a no-brainer to carry.- Reviewed by Ultralight Outdoor GearFeaturesBreathableFully Seam TapedLightweightMovement Mirroring StretchWaterproofWindproofAdjustable Back CinchFloating Foam-Stiffened BrimPackableSpecificationsSmall Weighs: 49gMedium Weighs: 52gLarge Weighs: 58gXLarge Weighs: 62gMaterial & Constructionbluesign approved Ventia 2.5L 100%Recycled Polyester 50D Mechanical Stretch Plain WeaveHelp & advice:Recycled Content in Outdoor GearThe Bluesign System
