Do \u003cstrong\u003enot\u003c\/strong\u003e dry clean (solvents destroy the DWR, the GORE-TEX membrane, and the 9% elastane in the upper bib).\u003c\/div\u003e\u003c\/div\u003e\u003cdiv class=\"key-section\"\u003e\u003cdiv class=\"key-title\"\u003eDrying\u003c\/div\u003e\u003cdiv class=\"key-desc\"\u003eTumble dry on \u003cstrong\u003elow to medium\u003c\/strong\u003e for 20–30 minutes after washing — the gentle heat reactivates the non-PFC DWR finish on the main body, upper bib, and kickpatches, restoring water beading. \u003cstrong\u003eHigher heat reactivates DWR better but don’t overdo it\u003c\/strong\u003e — sustained high heat can damage the Spectra® ripstop, the 9% elastane in the upper bib, the PU coating on the YKK® AquaGuard® zippers, and the gripper elastic on the hem gaiters. Hang dry is also fine if you tumble briefly afterward to restore water beading.\u003c\/div\u003e\u003c\/div\u003e\u003cdiv class=\"key-section\"\u003e\u003cdiv class=\"key-title\"\u003eDWR Re-Proofing\u003c\/div\u003e\u003cdiv class=\"key-desc\"\u003eWhen water stops beading on the 75D × 75D 134 g\/m² GORE-TEX Pro body, the 75D × 150D 242 g\/m² upper bib, or the 420D × 500D 250 g\/m² DRYVENT™ 2L kickpatches, re-treat with a \u003cstrong\u003espray-on DWR\u003c\/strong\u003e rated for GORE-TEX — Nikwax TX Direct or Granger’s Performance Repel are the right products. Apply to the clean, damp bib, paying extra attention to the shoulders, upper bib (most exposed to snow on chest-deep days), and the kickpatches (most abrasion from ski edges + crampon straps). A short low-heat tumble helps set the finish.\u003c\/div\u003e\u003c\/div\u003e\u003cdiv class=\"key-section\"\u003e\u003cdiv class=\"key-title\"\u003eGORE-TEX® Pro Membrane Care\u003c\/div\u003e\u003cdiv class=\"key-desc\"\u003eGORE-TEX Pro 3L is the most durable GORE-TEX tier — built for the most demanding conditions. Avoid folding or compressing the bibs tightly for long periods, which can crack the membrane. Store hanging or loosely folded. Don’t store wet, and don’t use harsh solvents, which destroy the membrane. With proper care, GORE-TEX Pro bibs last 5–10 years of regular backcountry use.\u003c\/div\u003e\u003c\/div\u003e\u003cdiv class=\"key-section\"\u003e\u003cdiv class=\"key-title\"\u003eSpectra® Ripstop Care\u003c\/div\u003e\u003cdiv class=\"key-desc\"\u003eSpectra® is one of the strongest commercial fibers in the world but isn’t indestructible. If a tear or hole appears (typical in extreme terrain), patch with a Spectra®-compatible adhesive patch (Tenacious Tape with Spectra® reinforcement works) or take to a professional repair service. Avoid grinding the bibs against sharp rock, ski edges, or crampon points — Spectra® is strong against tearing but not against abrasion over time.\u003c\/div\u003e\u003c\/div\u003e\u003cdiv class=\"key-section\"\u003e\u003cdiv class=\"key-title\"\u003eSuspender + Drop-Seat Hardware\u003c\/div\u003e\u003cdiv class=\"key-desc\"\u003eThe spring-loaded locking cam on the suspenders is durable but mechanical — keep it clear of ice and snow buildup, which can jam the locking mechanism. If it stops self-equalizing, a quick rinse with warm water and a light silicone lubricant restores function. The two-way side zips provide drop-seat functionality; the #5 YKK® VISLON® AquaGuard® zippers take a lot of use — lubricate sparingly with a silicone-based zipper lubricant (Nikwax, GE Silicone II) if they start sticking, and \u003cstrong\u003enever force a stuck zipper\u003c\/strong\u003e — back it off and clear debris.\u003c\/div\u003e\u003c\/div\u003e\u003cdiv class=\"key-section\"\u003e\u003cdiv class=\"key-title\"\u003eKickpatch Inspection\u003c\/div\u003e\u003cdiv class=\"key-desc\"\u003eThe 420D × 500D 250 g\/m² DRYVENT™ 2L kickpatches are designed to take abuse from ski edges + crampon straps, but they’re the highest-wear zone on the bibs. Check the kickpatch stitching and seam-seal adhesion periodically — if the kickpatch seam starts to lift (a common wear point), re-seal with seam-seal adhesive before it becomes a leak path.\u003c\/div\u003e\u003c\/div\u003e\u003cdiv class=\"key-section\"\u003e\u003cdiv class=\"key-title\"\u003eJacket-to-Pant Integration\u003c\/div\u003e\u003cdiv class=\"key-desc\"\u003eThe jacket-to-pant integration point at the back waist creates a one-piece seal with the compatible Men’s Summit Tsirku GORE-TEX® Pro Jacket — when paired, the two pieces connect and prevent snow from entering up the back. This integration is built to be unobtrusive; you don’t need to disconnect it to use the drop-seat zips, but be aware that the two pieces move as one when fully integrated. If you don’t have the matching jacket, the integration point folds flat and is unnoticeable.\u003c\/div\u003e\u003c\/div\u003e\u003cdiv class=\"key-section\"\u003e\u003cdiv class=\"key-title\"\u003eStorage (Off-Season)\u003c\/div\u003e\u003cdiv class=\"key-desc\"\u003eStore \u003cstrong\u003eclean, dry, and uncompressed\u003c\/strong\u003e in a cool, dark, dry place — hang on a wide hanger or fold loosely. Never store the bibs in a compression stuff sack for long periods (the Tsirku doesn’t have one, but if you do) — extended compression cracks the GORE-TEX Pro membrane and degrades the non-PFC DWR. Keep out of direct sunlight (UV degrades the GORE-TEX Pro membrane, the Spectra® ripstop, and fades the recycled polyester over time). Hang the suspenders over the hanger to keep the elastic spring-loaded cam from deforming.\u003c\/div\u003e\u003c\/div\u003e\u003c\/div\u003e\u003c\/div\u003e\u003c\/div\u003e\u003cdiv id=\"torrent-scanner-popup\" style=\"display: none;\"\u003e\u003c\/div\u003e\u003c\/body\u003e\u003c\/script\u003e\n\u003c\/body\u003e","brand":"my shop","offers":[{"title":"Bark Mist\/TNF Black \/ XS - Regular","offer_id":54371530146139,"sku":"NF0A8C9DD0L10XSREG","price":392.0,"currency_code":"GBP","in_stock":true},{"title":"Bark Mist\/TNF Black \/ XS - Short","offer_id":54371530178907,"sku":"NF0A8C9DD0L10XSSHT","price":392.0,"currency_code":"GBP","in_stock":true},{"title":"Bark Mist\/TNF Black \/ XS - Long","offer_id":54371530211675,"sku":"NF0A8C9DD0L10XSLNG","price":392.0,"currency_code":"GBP","in_stock":true},{"title":"Bark Mist\/TNF Black \/ S - Regular","offer_id":54371530244443,"sku":"NF0A8C9DD0L100SREG","price":392.0,"currency_code":"GBP","in_stock":true},{"title":"Bark Mist\/TNF Black \/ S - Short","offer_id":54371530277211,"sku":"NF0A8C9DD0L100SSHT","price":392.0,"currency_code":"GBP","in_stock":true},{"title":"Bark Mist\/TNF Black \/ S - Long","offer_id":54371530309979,"sku":"NF0A8C9DD0L100SLNG","price":392.0,"currency_code":"GBP","in_stock":true},{"title":"Bark Mist\/TNF Black \/ M - Regular","offer_id":54371530342747,"sku":"NF0A8C9DD0L100MREG","price":392.0,"currency_code":"GBP","in_stock":true},{"title":"Bark Mist\/TNF Black \/ M - Short","offer_id":54371530375515,"sku":"NF0A8C9DD0L100MSHT","price":392.0,"currency_code":"GBP","in_stock":true},{"title":"Bark Mist\/TNF Black \/ M - Long","offer_id":54371530408283,"sku":"NF0A8C9DD0L100MLNG","price":392.0,"currency_code":"GBP","in_stock":true},{"title":"Bark Mist\/TNF Black \/ L - Regular","offer_id":54371530441051,"sku":"NF0A8C9DD0L100LREG","price":392.0,"currency_code":"GBP","in_stock":true},{"title":"Bark Mist\/TNF Black \/ L - Short","offer_id":54371530473819,"sku":"NF0A8C9DD0L100LSHT","price":392.0,"currency_code":"GBP","in_stock":true},{"title":"Bark Mist\/TNF Black \/ L - Long","offer_id":54371530506587,"sku":"NF0A8C9DD0L100LLNG","price":392.0,"currency_code":"GBP","in_stock":true},{"title":"Bark Mist\/TNF Black \/ XL - Regular","offer_id":54371530539355,"sku":"NF0A8C9DD0L10XLREG","price":392.0,"currency_code":"GBP","in_stock":true},{"title":"Bark Mist\/TNF Black \/ XL - Short","offer_id":54371530572123,"sku":"NF0A8C9DD0L10XLSHT","price":392.0,"currency_code":"GBP","in_stock":true},{"title":"Bark Mist\/TNF Black \/ XL - Long","offer_id":54371530604891,"sku":"NF0A8C9DD0L10XLLNG","price":392.0,"currency_code":"GBP","in_stock":true},{"title":"Bark Mist\/TNF Black \/ XXL - Regular","offer_id":54371530637659,"sku":"NF0A8C9DD0L1XXLREG","price":392.0,"currency_code":"GBP","in_stock":true},{"title":"Bark Mist\/TNF Black \/ XXL - Short","offer_id":54371530670427,"sku":"NF0A8C9DD0L1XXLSHT","price":392.0,"currency_code":"GBP","in_stock":true},{"title":"Bark Mist\/TNF Black \/ XXL - Long","offer_id":54371530703195,"sku":"NF0A8C9DD0L1XXLLNG","price":392.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1029\/1724\/3227\/files\/NF0A8C9DD0L-HERO.jpg?v=1792089280","url":"https:\/\/hmpa.shop\/products\/the-north-face-mens-summit-series-tsirku-gtx-pro-bib","provider":"Josselyn Bach","version":"1.0","type":"link"}
