First, we designed optional, removable Internal Frames that specifically fit (and retrofit) into the Aeronaut 30 and Aeronaut 45. There's also a new optional, removable Padded Hip Belt, which you can use together or separately with the Internal Frame (the \u003ca href=\"https:\/\/www.tombihn.mom\/products\/aeronaut-padded-hip-belt\"\u003eAeronaut Padded Hip Belt\u003c\/a\u003e is available for purchase separately over here).\u003c\/p\u003e\n\u003cp\u003eBoth the Internal Frame and Padded Hip Belt are designed to add comfort and structure to the experience of carrying a more heavily-packed Aeronaut in backpack mode while waiting in long lines (well, let's hope not) at the airport or choosing to make a long trek across town to one's hotel on foot. \u003c\/p\u003e\n\u003cp\u003eThe Internal Frames are made of die-cut 0.055” \/ 1.4mm thick High Density Polyethylene (HDPE), with a nylon webbing sleeve sewn down the center that encases a 1” \/ 25mm wide 6061 aluminum stay. We’ve pre-bent the stay to a generic spinal curve; if you'd like, you can re-bend and\/or adjust the curvature to best fit your own back (\u003ca href=\"https:\/\/vimeo.com\/80286623\"\u003esee here\u003c\/a\u003e for video instructions demonstrating how to do this with the Guide's Pack frames; the same method applies to the Aeronaut frames).\u003c\/p\u003e\n\u003cp\u003eTo achieve the full benefit of using the Aeronaut 30 or 45 Internal Frame to shift some of the weight of the pack onto your hips, you may want to pair it with the Aeronaut Padded Hip Belt. \u003c\/p\u003e\n\u003cp\u003eIf you just want a frame sheet, the stay is removable, though it's worth noting that a frame sheet sans aluminum stay does just about nada when it comes to shifting the weight of the pack onto one's hips. (Read more about that here in our \u003ca href=\"https:\/\/blog.tombihn.mom\/guide-backpack-frames\"\u003eOur Guide to Internal Frames\u003c\/a\u003e.) \u003c\/p\u003e\n\u003cp\u003eBoth sizes of frame feature four pie-slice cut-outs that save a bit of weight, but more importantly allow the frame to flex\/twist with you as walk. Unlike the “lobe-in-pocket” retention system of the \u003ca href=\"\/products\/the-guides-pack\"\u003eGuide's Pack\u003c\/a\u003e and the \u003ca href=\"\/products\/heros-journey-travel-backpack\"\u003eHero's Journey\u003c\/a\u003e, the Aeronaut Internal Frame is held in position inside the bag by its hourglass shape: the frame over-centers (sort of “pops”) into place. Though the internal frame is in no way \u003ci\u003efree-floating\u003c\/i\u003e inside your bag, we wanted to make sure that the cut edge of the HDPE won’t ever be able to abrade the interior fabric panels of your Aeronaut, so we bind the edges with 400d nylon fabric . . . just to be sure.\u003c\/p\u003e\n\u003cp\u003eInstalling the Aeronaut 30 and 45 Internal Frames is pretty straight-forward; step-by-step instructions can be \u003ca href=\"https:\/\/blog.tombihn.mom\/how-to-aeronaut-internal-frame-padded-hip-belt\"\u003efound on our blog\u003c\/a\u003e.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePlease note: Aeronaut 45s made before 2014 have a slightly shorter back compartment, which means you'll need to use the Aeronaut 30 Internal Frame. If the main compartment dividers of your Aeronaut 45 are secured with snaps as opposed to zippers, you have an Aeronaut 45 made before 2014.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eIn doubt as to which vintage of Aeronaut you have? \u003ca href=\"mailto:emailus@tombihn.mom\"\u003eemailus@tombihn.mom\u003c\/a\u003e or give us a call at 1-800-729-9607 or +1-206-652-4123.\u003c\/p\u003e\n\u003cp\u003eBenefits of an Internal Frame\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eOn bags with a webbing or padded hip belt (see the \u003ca href=\"https:\/\/www.tombihn.mom\/products\/aeronaut-padded-hip-belt\"\u003eAeronaut Padded Hip Belt\u003c\/a\u003e), the vertical stability facilitated by an internal frame with an aluminum stay can help to lift some of the pack’s weight onto one's hips.\u003c\/li\u003e\n\u003cli\u003eIt creates a hard back panel that prevents less-than-carefully packed objects like a thermos or DSLR from poking one in the back.\u003c\/li\u003e\n\u003cli\u003eIt can prevent an overstuffed bag from barreling out against one's back.\u003c\/li\u003e\n\u003cli\u003eTo some folks, a rigid frame against their back (with padding between the frame and their pack) just feels right.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eWhy You Might not Want to Use a Frame\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eA frame adds weight to a bag. Our Aeronaut 45 Internal Frame weighs 9.9 ounces \/ 280 grams and our Aeronaut 30 Internal Frame weighs 8.6 ounces \/ 245 grams. In many cases, you can forego the frame and achieve similar benefits with careful and thoughtful packing: carry less stuff, carry lighter stuff, and arrange it all carefully so it doesn’t poke into your back.\u003c\/li\u003e\n\u003cli\u003eSoft luggage has myriad advantages over rigid luggage, and an internal frame converts the Aeronaut into a bag that's somewhere in-between soft and rigid luggage. The rigidity offered by the internal frame could become a liability when you’re squeezing your pack into the baggage sizer, in the overhead compartment or under the seat in front of you. That's a reason it's nice to be able to remove the internal frame when you want to.\u003c\/li\u003e\n\u003cli\u003eSome folks simply prefer the feeling of a frameless or soft-back pack.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eFor more on our philosophy and experience regarding internal frames, please see our \u003ca href=\"https:\/\/blog.tombihn.mom\/guide-backpack-frames\"\u003eGuide to Internal Frames\u003c\/a\u003e.\u003c\/p\u003e\n\u003cp\u003eMore reading:\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/blog.tombihn.mom\/the-aeronaut-travel-bag-frequently-asked-questions\"\u003eAeronaut Frequently Asked Questions\u003c\/a\u003e\u003cbr\u003e\u003ca href=\"https:\/\/blog.tombihn.mom\/how-to-aeronaut-internal-frame-padded-hip-belt\"\u003eHow to Install the Aeronaut Internal Frame + Padded Hip Belt\u003c\/a\u003e\u003cbr\u003e\u003ca href=\"https:\/\/blog.tombihn.mom\/guide-backpack-frames\"\u003eOur Guide to Internal Frames\u003c\/a\u003e\u003cbr\u003e\u003ca href=\"https:\/\/blog.tombihn.mom\/brief-history-of-padded-hip-belts\"\u003eHistory of Padded Hip Belts\u003c\/a\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"TOM BIHN","offers":[{"title":"Aeronaut 30","offer_id":8737225211967,"sku":"TB1812-BA","price":36.0,"currency_code":"USD","in_stock":true},{"title":"Aeronaut 45 Internal Frame","offer_id":8737225244735,"sku":"TB1813-BA","price":36.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1089\/8530\/files\/A30-Frame-Sheet.jpg?v=1706716048","url":"https:\/\/www.tombihn.mom\/products\/aeronaut-30-or-45-internal-frame","provider":"TOM BIHN","version":"1.0","type":"link"}
