The combination of underarm and back ventilation zips with that high breathability rating helps prevent the clammy build-up common in lower-spec waterproofs during physical work.\u003c\/p\u003e\n\u003ch2\u003eAlso Known As\u003c\/h2\u003e\n\u003cp\u003eAlso searched for as: SIP Keiu jacket, hi-vis waterproof jacket, EN 343 rain jacket, arborist rain jacket.\u003c\/p\u003e\n\u003ch2\u003eFAQs\u003c\/h2\u003e\n\u003cdetails\u003e\u003csummary\u003eHow waterproof is this jacket?\u003c\/summary\u003e\u003cp\u003eIt's certified to EN 343 Class 4-4-X, the highest rating for both water penetration resistance and breathability under the standard.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eDoes it have ventilation?\u003c\/summary\u003e\u003cp\u003eYes, ventilation zippers under the arms and on the back help regulate temperature during physical work.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eIs the hood detachable?\u003c\/summary\u003e\u003cp\u003eThe hood is foldaway and stores neatly in the collar rather than detaching.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eHow many pockets does it have?\u003c\/summary\u003e\u003cp\u003eTwo chest pockets and one internal pocket.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eIs it suitable for tree surgery and climbing work?\u003c\/summary\u003e\u003cp\u003eYes, the relaxed ergonomic fit allows full range of motion, making it suitable for tree surgery, climbing and other outdoor work.\u003c\/p\u003e\u003c\/details\u003e","brand":"SIP Protection","offers":[{"title":"S","offer_id":45718512009460,"sku":"SI-1SMR-570-S","price":220.0,"currency_code":"USD","in_stock":true},{"title":"M","offer_id":45718512042228,"sku":"SI-1SMR-570-M","price":220.0,"currency_code":"USD","in_stock":true},{"title":"L","offer_id":45718512074996,"sku":"SI-1SMR-570-L","price":220.0,"currency_code":"USD","in_stock":true},{"title":"XL","offer_id":45718512107764,"sku":"SI-1SMR-570-XL","price":220.0,"currency_code":"USD","in_stock":true},{"title":"XXL","offer_id":45718512140532,"sku":"SI-1SMR-570-2XL","price":220.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0690\/6603\/1348\/files\/SIP_PROTECTION_Keiu_Hi-Vis_Rain_Jacket.jpg?v=1756826609","url":"https:\/\/www.gustharts.com\/en-us\/products\/sip-protection-keiu-hi-vis-rain-jacket","provider":"Gustharts","version":"1.0","type":"link"}
